TripIt: 1) call oauth_callback to authorize URL, 2) error message: state token is invalid or has expired about apps-script-oauth1

Add .setParamLocation('uri-query') on your service to specify that the OAuth parameters should be passed via URL instead of the Authorization header:

As for the second issue, ensure that you are using the right project key.

Thanks Erick for the quick reply.

I believe the setParamLocation is used for the other steps in the process.
The authorization URL is just a URL (not a POST request), right?
And, for those other steps: TripIt does expect them in the auth header, so the default option should be ok.
To be sure I tested it as you suggested:

• the URL still needs to be manually modified to include the oauth_callback parameter
• the same macro error message

I double checked: the project key is correct.
When I use an incorrect project key I get a different error message: Sorry, the file you have requested does not exist
Are there specific permissions needed?

update: here is the list of combinations I tried:

• .setParamLocation('auth-header').setMethod("get"): no oauth_callback in the URL (and no state)
• .setParamLocation('auth-header').setMethod("post"): same
• .setParamLocation('uri-query').setMethod("get"): same
• .setParamLocation('uri-query').setMethod("post"): same
• .setParamLocation('post-body').setMethod("get"): TripIt API error 102.1 - consumer key is missing
• .setParamLocation('post-body').setMethod("post"): TripIt API error 104.1 - invalid signature

For the macro URL, I noticed it looks different than the one in the other issue:
https://script.google.com/a/macros/fancy-domain.org/d/ProjectId/usercallback?state=ADE...ygJf&oauth_token=b4f...92e&oauth_verifier=d30...225

In mine there is no oauth_verifier or state.

I just submitted commit a3fb1f1, which should resolve the issue. Tripit uses OAuth version 1.0, instead of 1.0a which the library was setup for. I made changes to support 1.0, and tested it with the Tripit API. Update to the latest version of the library and call setOAuthVersion('1.0') when building the service.

Fantastic Erick!
Thanks for the very quick and very useful response.
I can confirm it works great now.
