I am trying to consume Google Oauth v2. I go into my api console and setup the following 2 redirect uris…

http://localhost:3000/auth/authenticate
http://localhost:3000/auth/google/getToken

When I run the following…

curl -d "code=<removed>&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fauth%2Fgoogle%2fgetToken&client_id=<removed>&client_secret=<removed>&grant_type=authorization_code" -X POST https://accounts.google.com/o/oauth2/token

everything works great, however,

curl -d "code=<removed>&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fauth%2Fauthenticate&client_id=<removed>&client_secret=<removed>&grant_type=authorization_code" -X POST https://accounts.google.com/o/oauth2/token

fails saying…

"error" : "redirect_uri_mismatch"

I did just change this, is there a propagation time frame? How do I get both uris to work?

    As described here the second time you send redirect_uri you send it for validation(they need to match) and this is not an arbitrary value. You need to pass the same value for redirect_uri when requesting for access token to the value of redirect_uri in which you asked user to be redirected after authorization. Otherwise google(or any other provider will generate an error message).
