Hello there.

I need help with implementing the eSignature API. I have a simple Word document with variables - {{contractor_name}}, {{contractor_email}}. How can I use the API to update this document and populate real data instead of {{contractor_name}} and send it to the recipient?

- I tried to use textTabs and send all the necessary data in one request, including a Word document in Base64 - the fields didn't populate.
- I tried to manually create a template using the web UI, upload a Word document, manually add sender fields, and then made a request to update these custom fields (docGenFormFields). Nothing. ChatGPT assumed that docGenFormFields wasn't turned on in my account. But how to turn it on, I have no idea.

I'm using the developer sandbox account. Can anybody point me to how to implement field population via API?

I've used:
Document generation manual - https://developers.docusign.com/docs/esign-rest-api/esign101/concepts/documents/document-generation/
Prefilled tabs - https://developers.docusign.com/docs/esign-rest-api/esign101/concepts/tabs/prefilled-tabs/
Recipient tabs - https://developers.docusign.com/docs/esign-rest-api/reference/envelopes/enveloperecipienttabs/

Thanks for any help
Andrew.
