Can you confirm you followed the go-live process to promote the integration key to the production environment? You also need to update the user Id, the account Id and the base URI to production as all of these values will be different to the demo environment.

You need to do all steps, including consent again in the production environment after the promotion of the integrator key.

Yes I went through and completed every step in the Go Live Process. 

Right now I am stuck on Step 2 

When trying to obtain the access token, I approve consent and that is where my error occurs. 

{

    "error": "invalid_grant",

    "error_description": "unauthorized_client"

}

@LWMyer 

The error message "invalid_grant" with the description "unauthorized_client" typically occurs during the OAuth 2.0 authorization process, indicating that there is an issue with the client credentials or permissions.

After you approve consent are you copying the return URL from the equal sign on..something like this but with a lot of characters. https://www.example.com/redirect?code=eyJ0eXAiOiJNVCIsImFsZyI6IlJTMjU2Iiwia2lkIjoiNjgxODVmZjEtNGU1MS00Y2U5LWFmMWMtNjg5ODEyMjAzMzE3In0.AQoAAAABAAYABwCAtMBJGiHcSAgAgEBHkRoh3EgCAE1

Also, make sure you are using the correct grant type. The error suggests that there might be a mismatch in the grant type being used and what is expected. Typically, this error is seen when using the Authorization Code Grant.
