I am on the API reference page and there’s a test request form at the footer of the page

when I try to send a request, I get “Invalid Access Token”

yep ok. so I created a JWT app and I click on get access token and past the client ID and key from my JWT app credentials and I get this message

clientId : cjakotxHRRW4x8XQihD13g cannot be invoked by userId : XXXMxyKRRhOz1obX4Z0I6g (4,700)

what am I doing wrong ?

Hi Rich,

The **Get Access token** dialog boxes for Client ID and secret are for inputing your client ID & Secret from OAuth based apps and not JWT apps. A workaround would be to go to your JWT app, under **View JWT token** [1], you’ll see an already generated JWT token for you account. Copy the JWT token and paste it, where it says **oauth\_access\_token** (see screenshot below), then press Send.
