Why do I keep getting "invalid_client" responses when trying to make API calls?

If you are seeing "invalid_client" it's usually assocaited with the API key being incorrect. This could be caused due to incorrect base64 encoding or incorrect client secret and clinet ID. We suggest contacting support to get a confirmation on your client ID and client secret. You can contact solution engineer by emailing api@signnow.com.
