send_for_signature
Send a PDF document for legally binding electronic signature via SignSimple (free, unlimited). Provide the PDF as a fetchable URL or base64, plus recipient name(s) and email(s). Each recipient is emailed a secure signing link; signature and date fields are placed automatically unless custom fields are given. Works with the free templates from list_templates (pass their pdf URL as document_url). Requires a SignSimple API key (create one at https://signsimple.app/profile).
