I haven't been able to authenticate with DocuSign's API using nodejs. These are the steps I have followed;
- I got the DocuSign code example running with JWT grant for node.
- I generated an Integration Key in the Sandbox environment
- I stored my private RSA Key and it's properly formed (it doesn't have trailing spaces).
But I keep getting this error (I also tried generating new integration keys but I get the same result)
API problem: Status code 400, message body:
{
"error": "invalid_grant",
"error_description": "no_valid_keys_or_signatures"
}
