Google API authentication: Not valid origin for the client

Question

When making an auth request to the Google API (gapi), it\'s returning false on the checkOrigin.

I have removed any client id\'s or anything that would link directly

Answer 1

Credentials do not work if API is not enabled. In my case the next steps were needed:

1. Go to https://console.developers.google.com/apis/library
2. Enter 'People'
3. From the result choose 'Google People API'
4. Click 'Enable'

Answer 2

Clear your browser cache. Started getting this error in Chrome and then I created a new client id and was still getting the issue. Opened firefox and it worked, so I cleared the cache on Chrome and it started working.

Answer 3

Creating new oauth credentials worked for me

Answer 4

Key Point: Add both http://localhost and http://localhost:port_number to the Authorized JavaScript origins box for local tests or development.

Answer 5

Trying on a different browser(chrome) worked for me and clearing cache on firefox cleared the issue.

(PS: Not add the hosting URIs to Authorized JavaScript origins in API credentials would give you Error:redirect_uri_mismatch)

Answer 6

try clear caches and then hard reload, i had same error but when i tried to run on incognito browser in chrome it worked.
