Tab values not filling when creating envelope from template via API

Question

Hi,I'm creating envelopes from a template using the REST API. The envelope is created successfully but all text field values remain empty.Setup:- Production account- POST /v2.1/accounts/{accountId}/envelopes- Text fields placed under Company Rep recipient- Tab labels are auto-generated UUIDsThings I already tried:- Sending tab values in templateRoles in the POST request- PUT request to update tabs after creation using tabLabel and tabId- Enabled "write initial value of fields for all recipients" settingAll attempts result in a correct draft but with empty fields.What is the correct way to pre-fill text tab values from a template via API?Thank you.

​@AbdulThe right approach depends on what kind of tabs those are.If the text fields are assigned to the Company Rep recipient, they are recipient tabs, not sender pre-fill tabs. In that case, the normal pattern is to set their values when you create the envelope from the template, inside the matching templateRoles[].tabs.textTabs[] object for that role. DocuSign’s tabs documentation distinguishes recipient tabs from sender pre-filled tabs, and the prefilled-tabs docs make clear that sender pre-fill fields are a separate tab type.https://developers.docusign.com/docs/esign-rest-api/esign101/concepts/tabs/prefilled-tabs/
