I auditioned about 10 different Chrome/Firefox extensions to send HTTP requests and this was by far the best one. It's clean, simple to use, and handles auth really well.

dfc3• 12 years ago

Do you remember your favorite for firefox? I have never found one that I was very happy with.

aritraghosh007• 12 years ago

I have tried RestEasy with FF and found it to be good.

wickedOne• 12 years ago

you might want to give restclient a go: been using it nearly daily for the last year and am quite happy with it. http://restclient.net/

Osiris• 12 years ago

I've been using Postman for quite a while now and it's really handy. You can save requests in collections so you can rerun the same requests for testing purposes. It's great if you're deving a REST API and need a simple client for basic testing.

jbl2• 12 years ago

It's also great for sharing collections of API calls as a sort of live demo.

theboss• 12 years ago

Super useful for testing web-apps for vulnerabilities

vtempest• 12 years ago

I've been using this for a while. I wish it had the feature of logging the http requests going on currently, similar to other addons or Wireshark.

viig99• 12 years ago

Postman comes with an interceptor which basically saves all the API request to postman while you are browsing through your site, https://chrome.google.com/webstore/detail/postman-intercepto...

How to use it, https://www.youtube.com/watch?v=Dxf-o_DLSLw

deanmoriarty• 12 years ago

And let's not forget is the only one I've seen that automatically remembers cookies, very very handy.

victormx• 12 years ago

the only flaw it's you can't see size of request without using chrome tab

jug6ernaut2• 12 years ago

I know i am missing something here....but how on earth do you launch this?

thematt• 12 years ago

Seriously, it's a pain in the ass. Click the apps launcher in the upper left of the Chrome start page.

jug6ernaut2• 12 years ago

Ah much appreciated, i never would have found that.

ttdmayshark• 12 years ago

I'm glad to know I'm not the only person who struggled with this.

hellbreakslose• 12 years ago

Add it to your favorites bar and then it will be much easier for you to launch it without going to the play store !

stretchwithme2• 12 years ago

Upper left just below the Forward and Back buttons is an Apps button.

Most people don't seem to see it as anything more than a bookmark. I searched the menus for it and did not find it. And it was sitting right there.

somlor• 12 years ago

Postman Launcher is pretty handy: https://chrome.google.com/webstore/detail/postman-launcher/i...

kcorbitt• 12 years ago

Chrome used to take you to the apps page on a new tab by default, which was really convenient. Several releases ago they replaced that default with an utterly redundant search bar on new tab pages for reasons I can't begin to understand. Anyway, you can just go to chrome://apps and bookmark that page.

austinheap• 12 years ago

Chrome's official 'App Launcher' is your friend https://chrome.google.com/webstore/launcher :-)

greenbee• 12 years ago

I've been using Postman for a while. Overall, very impressed as it was intuitive straight from the first use. However, when putting files in a post request, it doesn't remember the files for you. Also, there is no way to stop an ongoing request besides resetting and clearing all the parameters. I really hope they would accommodate these options in the future.

a857• 12 years ago

There is now a new Chrome API which can help remember files. Looking into it right now.

jroseattle• 12 years ago

I use both postman and restconsole alternatively for testing our JSON API. Wrapped in with the console open to the Network, it's indispensable.

ShaneCurran• 12 years ago

I've been using Postman pretty much every day for the past couple of years. It's a really handy tool for testing out APIs in particular which is primarily what I use it for. It's definitely worth upgrading your package and I think the developer well deserves it.

pingburg• 12 years ago

I've used Postman for a while and it is great for those trying to understand integrating with web apis. The ability to save requests in a namespace is invaluable.

stock_toaster• 12 years ago

I prefer cli tools for api driving/testing, and httpie[1] works pretty well for that.

[1] https://github.com/jkbr/httpie

a857• 12 years ago

I like httpie but the app can do a lot more than sending requests now (which you might not be able to do in a CLI tool). You can write tests and run a bunch of requests together to simulate different scenarios: http://www.getpostman.com/docs/jetpacks_writing_tests.

glutamate• 12 years ago

Here's a library in Haskell if you are inclined to do this with an embedded domain-specific language instead:

http://hackage.haskell.org/package/http-test

jjm• 12 years ago

Then throw HTTPie into a bash script.

abritishguy• 12 years ago

There are lots of things that you can do easily with postman but would be difficult with a CLI tool.

SixSigma6• 12 years ago

I doubt that completely, citation needed.

mlni• 12 years ago

Chrome dev tools make testing RESTful backends with curl very easy: right-click on a request in network panel and choose "Copy as curl". Priceless little gem.

malkia• 12 years ago

postman turned real useful for me while getting some jira rest stuff to work

rdvrk• 12 years ago

Super useful. It's nice that you can set auth parameters (basic/digest/oauth1&2) and headers easily.

I use it as a packaged app, so launching it is the same as it is for native stuff.

te_chris• 12 years ago

I use Rested, it's a simple, cheap, mac app and works great. http://www.helloresolven.com/portfolio/rested/

EDIT: Why the hell was I downvoted for suggesting a good app? goddammit...

jonahx• 12 years ago

probably because your suggesting a paid app to solve a problem that is well solved by free ones

LocalPCGuy• 12 years ago

Also a Mac app when the original app works across platforms

dwightgunning• 12 years ago

Not sure but potentially because your comment is a bit tangential.... If you anchor your recommendation to Postman in some way then it may make a stronger statement and/or take the conversation in an interesting direction?

Can you tell us how Rested compares with Postman in terms of features and any pros/cons you found?

dfc3• 12 years ago

In addition to the other suggestions, there is also the usual suspects:

  * fat fingered an upvote
  * vote ring detection evasion bot randomly selected you
    for an upvote

TomAnthony• 12 years ago

This looks great! Thanks a lot for the recommendation, I'm going to buy it now. Postman also looks good so installed that too!

(I think your comment was fine - it serves a similar purpose so if people are interested in this thread there is a good chance [like me] they might be interested in this too.)

konstruktor• 12 years ago

http://ycombinator.com/newsguidelines.html Resist complaining about being downmodded. It never does any good, and it makes boring reading.

karangoeluw• 12 years ago

I'll recommend Postman to anyone any day. I make a ton of API's and it's the best tool for testing them.

nodesocket• 12 years ago

Postman is an awesome tool. If your intereseted in a php library to go a bit further and curl urls and expect certain json response bodies, headers, and status codes, check out https://github.com/commando/dogpatch.

atonse• 12 years ago

I love postman but am not a fan of the just slightly weird behavior of chrome apps.

hdra3• 12 years ago

Would be perfect if it can stop being a chrome packaged app though. The window switching in OS X makes it really hard for me to get to it when I have a chrome window open at the same time.

I wish it could be wrapped in a native app or even just let it run in a chrome tab.

solox3• 12 years ago

Believe it or not, Postman was better (used to run inside a tab instead of its own window)

Edit: here it is, both the extension (tab) and the packaged app (window): https://chrome.google.com/webstore/search/postman?hl=en

hdra3• 12 years ago

Yes, I know about that POSTMAN used to run inside a tab, but it seems to have been abandoned for quite some time. I still have it installed, but it still telling to to 'upgrade' to the packaged app.

That Postman extension that you linked, I actually didn't know about this before, but that doesn't seems like something provided by the original developer. Any idea whats the story behind it? EDIT: Nevermind, just Googled the domain. Its the same developer.

girvo2• 12 years ago

Command + backtick will help in those cases. :)

hdra3• 12 years ago

Yes, but for me, most of the time it's more of a Cmd+Tab to Chrome from my iTerm or ST, and then Cmd+` several times to finally find it.

And when you do it hundreds of times, it gets seriously tedious.

jbl2• 12 years ago

What behavior are you looking for? I noticed that recently (maybe with a Chrome update?) that packaged apps run/show up as independent apps in the OS X task switcher.

a857• 12 years ago

Trying to improve Cmd + Tab behavior on all platforms. This is really a Chrome issue and am waiting for improvements in the platform.

BHSPitMonkey• 12 years ago

Packaged apps can make requests without being subject to the normal XHR security rules (e.g. no Cross-Origin request problems), among other features like native TCP/UDP sockets.

skastel• 12 years ago

If you're looking for something with a lot of great features for in a web app that you can leave running in a tab check out our product: www.runscope.com It's great for recording http calls, editing and retrying and sharing. Plus we've got test suites and can import your Postaman collections to help get you started!

Dobbs• 12 years ago

Slightly off topic but look into witch (http://manytricks.com/witch/) for better OSX window switching. I have alt+tab configured to switch between windows on the current desktop that aren't hidden.

shivaas• 12 years ago

love this tool!! indispensible if you are working with a REST api, or even debugging SOAP responses

lilpirate2• 12 years ago

Postman works great. The only feature I would like to see added is to somehow easilu swap a base URL in requests. So I have to maintain just one collection per API and not multiple collections for multiple API deployments (production, testing, staging).

sqren• 12 years ago

You can do that with environments: http://www.getpostman.com/docs/environments

redwoolf• 12 years ago

You can do this by using the environments feature. Create an environment and add a key to that environment to represent the base URL. Then in the the URL line replace your base URL with the reference to the key. For example http://{{base-url}}/api/

lilpirate2• 12 years ago

Aha. I thought environments could only be used for setting additional HTTP headers! Thanks for this.

threeseed• 12 years ago

Also would take a look at SoapUI if you are dealing with multi step flows:

http://www.soapui.org

sleepyhead2• 12 years ago

Perhaps the worst software I have ever used.

mnkypete2• 12 years ago

maybe for REST, but seriously, if you ever need to test SOAP services - I hope you don't - this is probably the best there is..

haswell• 12 years ago

I regularly use SoapUI for standing up mock services of 3rd party web services and any time a web service needs something WS-Security related. That said, I find it clunkier than I'd prefer and I use https://chrome.google.com/webstore/detail/wizdler/oebpmncolm... any time I just need a quick request envelope for some WSDL.

uuid_to_string• 12 years ago

Our current testing utilities are relatively small and compile with modest amounts of RAM. Hobbit's netcat, WR Stevens' sock, etc.

We have security auditing rules that require us to compile the programs we run from source. We prefer small programs as they are easier to audit.

Does anyone know how much RAM is required to compile Chromium?

Can it be done on a laptop?

dfc3• 12 years ago

Do you have to compile everything from source, e.g. gcc, glibc, etc? There is no need to get into the whole "reflections on trusting trust" spiel, but I imagine at some point you must rely on your distro? Just use the chromium package from your distro. If not why not build on a desktop/server and copy package to laptop?

mnkypete2• 12 years ago

I would not recommend that. I compiled Chromium a few month ago with my i7 desktop with 8gig ram and it took at least an hour to finish, if not longer. I don't think RAM is that much of an issue, but I wouldn't go lower than at least 4gig of RAM.

free• 12 years ago

I switched to Postman because it supports attaching files to make multipart request, which the RestClient does not.

a857• 12 years ago

Thanks for the great comments everyone. Postman developer here. Woke up to find the link at the top of HN. Feels awesome. :)

SimonW432• 12 years ago

Thanks for the great tool.

First I thought "Damn, that's no news. I use it for ages ...", but some things are worth to be reminded of from time to time.

a857• 12 years ago

Haha. You are welcome!

jorde• 12 years ago

It has been part of my developer toolkit for a year and I absolutely love it! I hope we can see OAuth2 auth sometime soon :)

tluyben2• 12 years ago

Thanks for your effort; the tool is fantastic! We use it every day for working with API's.

jabo• 12 years ago

Great job! Really useful tool.

On a side note, it's interesting how, though you posted postman on HN a couple of times before, it hit the front page only now.

n8m• 12 years ago

Thanks for that great tool! You're my firebug for API's.

pascalo• 12 years ago

Thanks for the great tool. I use it daily at the moment. Gotten much better over the last few months as well.

blisterpeanuts• 12 years ago

I love Postman. It came in very handy when I was starting to develop some web apps that use POST JSON packets. Although I've since developed some cURL scripts to do equivalent tasks from the command line, I find Postman's features to still be very handy, especially history, auto-complete, and the handy GUI visual approach. Both Postman and cURL are essential tools to my work. Thanks for providing this great tool!

Ind007• 12 years ago

I find Advanced REST Client is more friendlier

https://chrome.google.com/webstore/detail/advanced-rest-clie...

andeh892• 12 years ago

We've been using Postman for a while now, it's invaluable for testing/validating APIs across our environments. One feature we've been waiting a long time for however is live collection sharing; to have a centralized set of endpoints/etc that's kept updated and synchronized (without needing everyone to export and import JSON files). There's a feature request on GitHub but it's been in stasis for a long time now.

jamra• 12 years ago

why not use something like zookeeper or etcd to sync your config files?

andeh892• 12 years ago

Interesting, I'll have a look into whether that's possible with the current client (my understanding was that Collections don't detect or update changes unless you explicitly make any yourself). Still, ideally this is something that'd be very handy to have as a core feature within the app (author has looked into Google Drive integration in the past)

a857• 12 years ago

Will have something which will solve this and much more very soon. I tried different alternatives (Drive/Dropbox) but none of them fit the amount of flexibility I wanted to have with collections.

lnanek2• 12 years ago

I use Simple REST Client for Chrome. This might have a few extra features, though, so guess I'll try it out. Seems like a common, over served extension idea, though.

forlorn• 12 years ago

for Chrome

Thank you but no.

SimonW432• 12 years ago

While I have issues with a lot of services Google provides I think Chrome is safe to use here. I don't think they're capturing your communication using Chrome (you could easily find out using Wireshark). They do in many other ways, though.

i39d• 12 years ago

Chrome is proprietary, use Chromium instead. If they aren't doing bad stuff today, they might implement bad stuff tomorrow and automatically push that update to you. You can't turn of updates in your browser, you have to edit the configuration file for the autoupdater. I prefer any Firefox or any Mozilla based browser, but that is just personal preference.

sinzone• 12 years ago

http://mashape.com is a proud supporter of Postman

politician• 12 years ago

Postman is an amazingly productive way to test or explore an API. It's a cheap win to export a request collection, and stick it in version control to capture the known state of an API at a point in time.

vitalus• 12 years ago

Our team's been using this for about 6 months as a regular part of our workflow. I now lean on it heavily while developing JSON APIs

jayjohnson• 12 years ago

Great tool we use during development of our REST APIs. Liking the collections for testing regressions too.

tzury• 12 years ago

Great tool, added to toolchain.

If you never came across Firefox Tamper Data Add-on, this might be a great opportunity to mention it.

https://addons.mozilla.org/en-US/firefox/addon/tamper-data/

A different tool, yet targeting similar audience (us).

munimkazia• 12 years ago

This tool is very popular in my place of work and geek circle. We've been using it for quite a while now.

domrdy• 12 years ago

I've been using this the past few days for testing elasticsearch queries, great tool!

"no more fiddling with the command line"

If you have to fiddle with the command line, you're doing it wrong. It drives us nuts in the Plan9 community that Bash history and readline is seen as some sort of productivity tool. We have powerful shell primitives but the command line is seen as the last resort of composing them. Admittedly we have a terminal window with which you can edit text in two dimensions but use a proper set of tools with a bit of forethought and you get much more done.

If you need an oauth client, write one with a few bits of script and use it everywhere. It's the Unix way.

sillysaurus3• 12 years ago

What would you recommend in terms of resources for learning the things you've mentioned?

canadev• 12 years ago

It drives us nuts in the Plan9 community that Bash history and readline is seen as some sort of productivity tool.

I don't understand what this means, can you explain?

I personally have a .bash_profile (more generally, a collection of dot files) in a git repo that I share between machines. I also find myself using Meta-. and CTRL-R quite frequently.

hasancc• 12 years ago

I've been using it for quite a while now. I'm ashamed to say that it's simplistic approach on collections often made me question the urgency of writing API documentation when developing a private API. Why not just send the collection of examples? Well, we all know why but still...

shaneqful• 12 years ago

Or you could just use curl.

digitalpacman• 12 years ago

Been using postman forever. But it needs lots of work.

chandraonline• 12 years ago

POSTman is an awesome testing tool and also a great way to document APIs to share within a team. I wish it had support for storing information in responses as variables for use in later requests. I currently use globals within environments to set things that rarely change like API keys and secret but it doesn't work for things that change in every invocation for eg., it would be nice if I can save the access token of an oath call in $token and then refer only to $token in other protected resources.

Garbage• 12 years ago

I am surprised how many people didn't know about Postman.

It's an amazing tool. I have been using it almost daily since long back.

joshmn• 12 years ago

I love the importing/exporting of collections. Makes sharing with my team so simple.

namigop• 12 years ago

{ Full disclosure, I'm the author of WCFStorm.Rest }

If you're on Windows and is looking for an alternative, check out wcfstorm.rest (http://www.wcfstorm.com/wcf/learn-more-rest.aspx). It has a lot features similar to postman and adds some more, like saving requests and responses into functional test cases which includes a showing a graphical "diff" between the actual and expected responses as well as being to define custom validation rules that is executed against the http response. It can also do a single load test as well a distributed load test using several machines (http://www.wcfstorm.com/wcf/how-to--distributed-performance-...)

WcfStorm.Rest is a paid software but it has a LITE version which is available for free and works well for ad-hoc testing and exploring REST API endpoints.

themez• 12 years ago

What impress me is that far they can go as a chrome app, chrome is turning into a platform like adobe air now. It's amazing.

reinier_s4g• 12 years ago

Postman is a great tool, i cant imagine developing applications nowadays without it.

cl8ton• 12 years ago

Postman is exactly what I have been looking for. I used Fiddler for years and always thought it to be heavy and awkward to use. It's strange I never heard about Postman before this post.

I like working out of the browser and Postman has just the right amount of features I need.

idlemind• 12 years ago

It's a great tool, we use it all the time on our team. It's the easiest way I've found to share a full demonstration of the API all in one go, with documentation. Couldn't live without it now!

ams6110• 12 years ago

Dev Http Client https://chrome.google.com/webstore/detail/dev-http-client/ae...

techaddict0092• 12 years ago

I had tried many other similar tool but all of them started crashing my chrome but Postman didnt cause any issue to performance of the browser.

I will suggest Postman for sure.

alex440• 12 years ago

I tried postman and found it rather weird. What did not suit me: problems with remembering history - i'd expect the much labored-at settings and vars and options to be stored in the cloud and not vanish if I re-install the extension or use other machine. no custom cookies - that's a deal breaker.

I prefer the excellent Fiddler tool for manual fiddling, and yet have to find a good test-suit tool. Or write it myself...

ninjakeyboard• 12 years ago

I've been using this for a while. I usually go to curl if I need to do any really heavy work but it's a handy quick tool.
