OAuth2 request failed: Service responded with error: 'bad client id: APP_ID_OR_ORIGIN_NOT_MATCH'

[Santiago Taco]

Good morning everybody,

I am trying to use Gmail APi in a chrome extension. I have reviewed this sample:

https://github.com/GoogleDeveloperExperts/chrome-extension-google-apis

If I use the same credentials the connection is fine but If I use my credencial it does not work.

I have created a Create an OAuth 2.0 client ID and I have enabled Gmail API service:

ID de clientes OAuth 2.0

	Nombre	Fecha de creación	Tipo	ID de cliente
testApi	10 abr. 2018	App de Chrome	93059932430.................................................oogleusercontent.com

When I install the extension I get this error:

Error2: OAuth2 request failed: Service responded with error: 'bad client id: APP_ID_OR_ORIGIN_NOT_MATCH'

Could someone help me with this problem?

Please make sure that the ext id you provide while generating the client ID matches with your extension ID. You can check this either in "more info" section in developer dashboard or under extension description in chrome://extensions

If that is correct then check whether or not you have added the public key in the manifest.json which is present under More info section in your listings in chrome developer dashboard.

Hey, i am having a similar problem. I think to add the public key will solve but i don't know where to put the public key at in the manifest file. When loading the extension I got an error because I had a 'key' object. I removed the 'key' object and now the extension won't work. So where does the public key go in the manifest?
