Calling Token API in Postman returning "error: invalid_client"

Calling Token API in Postman returning "error: invalid_client"

Hello,

I've been working on setting up an API to get data from zoho crm into a third-party application. I'm currently testing the setup in Postman, but I'm getting an error from the API to retrieve the access token. 

It keeps returning "error: invalid_client". I'm hard pressed on what the issue is since I copied the client ID directly from the Self Client application in the API console. 

Here's the API call:


I'm doing a post call to retrieve the access token from the API. As in the documentation I'm sending the grant_type, client_id, client_secret, redirect_uri, and code within the request body as form-data.

Does anybody know what's causing this issue?

Thank you,

Aaron.
