Google API authentication: Not valid origin for the client
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 to my account and replaced it with a regex indicating what the data is for reference. Url: https://accounts.google.com/o/oauth2/iframerpc?action=checkOrigin&origin=https%3A%2F%2Flocal.tools&client_id=(\d{21}) My origin url is a local url, which is https://local.tools Result: {valid: false} I'm using the example found here without deviation (except for replacing clientid with my 21 digit clientid): https://ga-dev-tools.appspot.com
