Adding, modifying, and removing signature fields

You can use the Signature service to add, modify, and remove visible and invisible signature fields from forms. When you add and modify signature fields, you can configure the following properties:

  • The field name and, for visible signature fields, the location.

  • The fields to lock when the signature is added.

  • The signature handler that validates signatures.

  • Information about the signature (for example, whether to include revocation information, a list of signing reasons that users can select from, and server URLs used for validating signatures).

  • Whether the field can be used only for certifying the document.

Important: The Signature service cannot add or modify signature fields on a dynamic Adobe PDF form.
