Docusign Integration - Changes in signer consent?

Hi, I work as an Integration Engineer for Unit4 and we’ve developed an integration between our ERPx platform and Docusign for document e-signing. We are now introducing some changes in the integration and we noticed an apparent difference on the signer consent process. We used to have a ‘consent_required’ error (HTTP response status 400) when requesting an OAuth token for the signer and we used it to identify that a given signer hadn’t yet given their consent. Currently it seems that all the signer consent process is dealt exclusively on Docusign UI. Can you please confirm if Docusign introduced any changes at the signer consent processing level?

Thanks in advance
