OAuth 2 is a standard way for third-party apps to get authorized access to a user's account without needing to copy/paste API keys or ask users for sensitive usernames and passwords.
We've added OAuth 2 directly to 37signals ID, so your apps can authorize a 37signals ID once then access any of its accounts on any product.
OAuth 2 implementation notes: * Start by reading the draft spec at http://tools.ietf.org/html/draft-ietf-oauth-v2 and trying the client libraries at http://wiki.oauth.net/OAuth-2 * We implement draft 5 and will update our implementation as the final spec converges, so be prepared for changes along the way. * We support the web_server and user_agent flows, not the client_credentials or device flows. * We issue refresh tokens. Use them to request a new access token when yours expires (2 week lifetime, currently). * We return more verbose errors than what's given in the spec to help with client development. We'll move these to a separate parameter later.
* We issue refresh tokens. Use them to request a new access token
when yours expires (2 week lifetime, currently).
So once you're authenticated, the token will expire after 2 weeks, and
the application will have to be re-authenticated? That could be a
problem for some applications where you set up a "connection" and
expect that connection to persist (say a web form -> Basecamp
application).
Unless I'm misunderstanding....

When your access token expires you use the refresh token to get a new one without user intervention.

My question concerns the step #3 (We redirect the user back to your app with a time-limited verification code.). How can we (in the third-party side) check that verification code has been generated for the client f...@bar.com.
here is a scenario: - two clients A...@domainA.com and B...@domainB.com try to authorize the same third-party application at the same time. - these clients get redirected to the same callback url (let's say https://server.com/_callback?code=X) where X is different for A and B. - in this case how could the callback server distinguish between the two verification code ? I mean how to be sure that a verification code belongs to a client A or B ?
Before redirecting user to 37signals authorization page I store in user session (in Ruby on Rails application) all necessary information that I need (e.g. is it client A or client B), when user will be redirected back, and when user is redirected back and I get their session (as their browser provide me session cookie with session ID) and I know which client it is.
Can the redirect_uri be different based on our user account information? For example, our customers each have their own custom domains so redirecting them back to a generic url will lose their session information.

We've switched to OAuth 2 exclusively with the new Basecamp API.
Basecamp Classic, Highrise, Backpack, and Campfire will continue to support API token authentication.

Yes. The new Basecamp is an all-new product with its own API, so it has its own Extras.
Thanks for this discussion. OAuth2 in-the-wild implementation details are a scarcity.
How do you authenticate your clients? If instead you consider your clients public, how do you identify them (or do you just tell the user they'll be redirected to so-and-so URL, leaving the client identification to the user)?

Clients register (to get a client_id and client_secret) and must authenticate to request access tokens. Since authorization is initiated from the client and redirects back to them, customers already know the client app.

Effectively, yes.
We have a handful of users who still haven't created a 37signals ID
since we introduced it in December 2009. If they want to use your app,
though, they'll be prompted to create their ID when they try to sign
in. So you can rely on everyone having a 37signals ID in practice.
Yep, just switched to OAuth2 for Highrise and BC Classic the other week,
works fine! Just don't understand why the tokens have to be so long,
sometimes >514bytes. Other services (i.e. Google, Evernote, Huddle, ... use
shorter strings)
Now experimenting with the new API also. In the case when a person has
multiple BC accounts (multiple 37signals ids), is there a way to ensure that
he authorizes to the intended one? For example, for BC Classic before Oauth
we still ask to specify the server name http://<company>.basecamphq.com and
then after the Oauth we compare if the access was given to that exact
server. I don't see a way to do something like that for the new basecamp.
Any suggestions?
Thank you

It's an HMAC-signed token that contains the authorization info, so it
takes a fair bit of space.
Is it causing problems for your client?

The common pattern is to reverse this flow: rather than ask for
http://<company>.basecamphq.com up front, authorize first, then fetch
the list of authorized accounts and ask this user which account to
connect to.

fine tuning now, two things though: the authentication dialog that appears to user does not always show the right products, when I chose Basecamp and Highrise it only shows Highrise, when i selected other products it shows the whole list of products... and so on... I just didnt understand the logic
second thing, when user clicks for a new authentication token, and my application has already gained access before, it still prompts user to give access again, instead of silently redirecting back to redirect_url... very unexpected behavior, is it by design?

A year ago we asked for a small change to at least have current user identity shown on the OAuth authorization page (https://groups.google.com/d/topic/37signals-api/yBo8CV6ixb0/discussion). Due to lack of this information, users with more than one Basecamp account often give access to the wrong one. This results in confused users, broken workflow and and various support issues. Unfortunately, 37signals didn't give a priority to this.

What if my account expires, but token is still valid?
How can I refresh an access token without registering new application to get new clientid and clientsecret?
