Given an `envelopeId`, this method returns the sender fields found in that envelope's documents. After you retrieve the sender fields, use the DocumentGeneration::updateEnvelopeDocGenFormFields method to populate the fields. If the specified envelope does not contain a document with sender fields, the method will return success (`200`) and an empty object (`{}`) in the response. ### Next steps - Learn about document generation in the eSignature concepts guide. - Learn how to send an envelope with document generation in your preferred coding language.
