Nylas API returns "Sorry, you must provide a valid client_id" error #1

Question and Answers
1

Hi,
I’m trying to connect to the Nylas API working on sandbox environment, but I keep getting this error:
{
“reason”: “Sorry, you must provide a valid client_id. The client_id request parameter should be the Client ID of your application in the Nylas Dashboard.”,
“error”: “access_denied”
}

Here’s what I’ve done:

Copied the Client ID directly from the Nylas Dashboard (verified multiple times).

Callback URI in my request matches exactly with the one configured in the Nylas Dashboard.

Checked multiple times for typos or formatting issues.

Why am I still receiving the “client_id” error even though the Client ID and callback URI are correct and verified? Is there any additional configuration or setting required?
