JWT Authentication failed

We are integrating Docusign with Moodle, it is showing the below error we want to get an access token. require_once(DIR.'/../../config.php'); require_once('../../vendor/autoload.php'); use DocuSign\eSign\Client\ApiClient; use DocuSign\eSign\Client\ApiException; use DocuSign\eSign\Configuration; use DocuSign\eSign\Api\EnvelopesApi; use DocuSign\eSign\Model\EnvelopeDefinition; use DocuSign\eSign\Model\Document; use DocuSign\eSign\Model\Signer; use DocuSign\eSign\Model\Recipients; use DocuSign\eSign\Model\Tabs; use DocuSign\eSign\Model\SignHere; use DocuSign\eSign\Model\RecipientViewRequest; $client_id = 'xxxx'; $user_id = 'xxxx'; $oauth_base_path = 'account-d.docusign.com'; $private_key = file_get_contents('private1.key'); $base_path = 'https://demo.docusign.net/restapi'; $expires_in_seconds = 3600; // Token validity period $scopes = 'signature impersonation'; // Initialize the API client $config = new Configuration(); $apiClient = new ApiClient($config); // Generate JWT and get the access token try { $apiClient->getOAuth()->setOAuthBasePath($oauth_base_path); $response = $apiClient->requestJWTUserToken($client_id, $user_id, $private_key, ['signature impersonation'], $expires_in_seconds); $access_token = $response[0]->getAccessToken(); $info = $apiClient->getUserInfo($access_token); $account_id = $info[0]['accounts'][0]["account_id"]; } catch (ApiException $e) { echo 'JWT Authentication failed: ', $e->getMessage(), PHP_EOL; if(strpos($e->getMessage(),'consent_required') !== false){ $authorizationURL = 'https://account-d.docusign.com/oauth/auth?'. http_build_query([ 'scope' => $scopes, 'redirect_uri' => 'http://localhost/moodle4', 'client_id' => $client_id, 'response_type' => 'code' ]); echo $authorizationURL; exit; }
}

@yugandhararao : Could you please confirm if you have obtained the required consent , before requesting JWT token. For more details please look at below link: https://developers.docusign.com/platform/auth/consent/obtaining-individual-consent/

Also could you please try passing scopes as string array like below: $scopes = ['signature', 'impersonation'];

@yugandhararao Can you please also confirm if your IK is set for proper grant type (i.e. auth code grant and not implicit grant).

Thank You.

Thank you both of you!! Resolved Moodle conflict with DocuSign jwt issue.

@yugandhararao May I know what the issue was ?

@garg-mudit The issue arose because Moodle and DocuSign were loading the same packages, such as JWT. I commented out the config.php file, and now it's working fine.
