# Update Signature Request

POST https://api.hellosign.com/v3/signature_request/update/{signature_request_id}
Content-Type: application/json

Updates the email address and/or the name for a given signer on a signature request. You can listen for the `signature_request_email_bounce` event on your app or account to detect bounced emails, and respond with this method.

Updating the email address of a signer will generate a new `signature_id` value.

**NOTE:** This action cannot be performed on a signature request with an appended signature page.
