Invalid Grant error while generation access token Docusign Salesforce API integration

Question

enter image description hereI created Sandbox developer docusign account to integrate Salesforce with Docusign and I am using this documentation link to authenticate Docusign i.e. https://developers.docusign.com/esign-rest-api/guides/authentication/oauth2-code-grant

and I am successfully able to generate authorisation code but getting an INVALID GRANT error while generating access token CURL used to generate i.e.

curl --data grant_type=authorization_code&code=eyJ0eXAiOiJNVCIsImFsZyI6IlJTMjU2Iiwia2lkIjoiNjgxODVmZjEtNGU1MS00Y2U5LWFmMWMtNjg5ODEyMjAzMzE3In0.AQkAAAABAAYABwCAjeI4mg3WSAgAgBlpgJoN1kgCAPoH-9oYVs9NtnQkVw517wIVAAEAAAAYAAEAAAAFAAAADQAkAAAAOGFhZWE4NDktMzQ5Ni00MWQ3LTlkMmYtZmVmZmNmMjA5MTEyMACAjeI4mg3WSBIAAQAAAAsAAABpbnRlcmFjdGl2ZQ.iqqgTue9mRNHQDL9CALsutAMgz6WreewSUqs39K1tSIuYMM8ADK9gp5FzFPb6D_Ozxow_AHDI2BGz0kyvN-0hwQ-H8nWmI4XrLeTFjRoWug2LtcE1wOGljTfOG1gc7eL7Xc6JpF86oXOPz7tkT4UQBDrtJ-uYB4XAum7Fa7zi9GcVQgW9bNe4jHfoLc8F3vKht3ZqjFh6KsWp3npqK62DUbdEX1QOVjUjxPXTsW4XOkhOZMxhm0h3bGPQu94NCGfgZ3EQ3tsISg5fPyu1YiYOmu2olLKb2VOc25l8SjAKXz5KH29iz5N5DpGSKZZQJI3g-QHddj3yUEXc7ndm861mQ

--header Authorization: Basic [[redacted]]

--request POST https://account-d.docusign.com/oauth/token

Please let me know what I am missing while generating access token.

Answer 1

DocuSign has recently updated the OAuth workflow so that there will be an error_description in addition to the error_code.

Common issues include:

• Expired Code (the code only lasts for a minute or two)

• Invalid Client ID or Secret in the Auth header

• Incorrect environment (Trying to make a Demo request against account.docusign.com or a Prod request against account-d.docusign.com)
