I’m following these docs: OAuth2 Authentication - Keap Developer Portal

Posting to this URL: https://api.infusionsoft.com/token

Headers:
Content-Type=application/x-www-form-urlencoded
Authorization=Basic [long encoded string]

Params:
grant_type=authorization_code
client_id=[my client ID]
client_secret=[my client ID]
redirect_uri=[my client ID]
code=[my client ID]

Getting this 400 error:
{
“error”: “InvalidClientIdentifier”,
“error_description”: “Invalid client identifier {0}”
}
Help pls

I am experiencing the same error, is there any resolution or different way of requesting a new token using the API? Any Keap developers available that can comment?
