# Update template (/api-reference/templates/updateTemplate)

Update an existing template. `name`, `folder`, `file_id`, and
`signers` are all optional in the request body.

- If `signers` is provided, it **replaces** the saved signer blueprint
  completely and new `field_id` values are generated for all elements.
- If `signers` is omitted, existing signers are preserved.
- If `file_id` is provided, it must belong to the authenticated user.
