Pinterest's official OAuth2 flow seemingly ret

Question

I followed the Pinterest's instructions to authenticate a user and after completing step 2 I am holding an access token in my hands. However, when I use this access token to make an API call I get the following response:

{"status": "failure", "code": 3, "host": "coreapp-devplatform-devapi-179", "generated_at": "Sat, 26 Sep 2015 15:11:35 +0000", "message": "Authorization failed.", "data": null}

When I use the Token Generator the API calls succeed. In both cases I tried:

https://api.pinterest.com/v1/me/?access_token=<YOUR-ACCESS-TOKEN>

Any ideas?

Answer 1

For those of you who are facing the issue when requesting for access_token in the post request include client_secret too in the 2nd step

https://developers.pinterest.com/docs/api/authentication/

i.e the post params while requesting this end point https://api.pinterest.com/v1/oauth/token will be:

grant_type Must be authorization_code

client_id This is your app ID.

client_secret This is your app Secret

code The authorization code passed to your redirect URI

Answer 2

Zack Argyle from Pinterest just tweeted that they deployed a fix which solves the problem I described: https://twitter.com/zackargyle/status/648602180002312192

Summing it up:

• Follow the instructions on https://developers.pinterest.com/docs/api/authentication/
• Pass the client_secret not in the first but in the second request
• Use response_type=code in the first request
