Hi Jason,
I am trying creating a new Client ID to access Google GMAIL API, It used to work until google has changed the way a client-Id is created, earlier while creating a client ID it used to ask for generate json and p12 files but now there is separate tab for this and i am assuming the service account json and p12 are not matching with the client ID secret.
now when i create a client id and authorize the gmail API and use the json and p12 files in my application user get “invalid grant” Error.
Is there a way to attach the json and p12 with a client-ID?
Hi,
I am facing error in accessing token for a authorized user having error “Invalid Grant”.
OAUTH2 “Invalid Grant” with a new ClientID, google has changed the way Client ID is created.
