zapassina
zapassina_add_signer
Add a signer to a document that is already sent. The signer joins at the end of the order and gets the invitation at once (or when their turn comes). This sends a real message. ZapAssina API: POST /docs/{token}/add-signer/.
zapassina_cancel_document
Cancel a document. Signing links stop working at once. This cannot be undone through the API. ZapAssina API: DELETE /docs/{token}/.
zapassina_create_document
Send a ready PDF for signature. Give exactly one of base64_pdf or url_pdf (PDF up to 25 MB). Set send_automatic_email only when the user asked to send the invitations now. Signature positions: anchors <<signer1>>, <<signer2>> and <<rubrica1>> in the PDF text. ZapAssina API: POST /docs/.
zapassina_create_document_from_template
Create a signing document from a template. Fill the template fields with data (de = field name, para = value). Set send_automatic_email only when the user asked to send the invitation now. Plan quota applies. ZapAssina API: POST /models/create-doc/.
zapassina_create_folder
Create a document folder. Missing parent levels are created too (up to 5 levels). ZapAssina API: POST /folders/.
zapassina_get_document
Show one document: status, signers with their status and signing links, answers, and file links. Returns the ZapAssina JSON. File links in the result expire after 60 minutes. ZapAssina API: GET /docs/{token}/.
zapassina_get_template
Show one template: its fields (inputs), signers, public link and extra documents. Use the fields before creating a document from it. ZapAssina API: GET /templates/{token}/.
zapassina_list_documents
List documents, newest first. Filters combine. Returns the ZapAssina JSON. File links in the result expire after 60 minutes. ZapAssina API: GET /docs/.

zapassina_move_document
Move a document to a folder. Missing folders are created. Use / to remove it from all folders. ZapAssina API: POST /docs/{token}/folder/.
zapassina_remove_signer
Remove a signer who has not signed yet. Their signing link stops working. If the others already signed, the document completes. ZapAssina API: DELETE /signers/{token}/.
zapassina_resend_invitation
Send the signing invitation again to pending signers who can sign now. Pass signer_token to send to one signer only. This sends a real message to the signer. ZapAssina API: POST /docs/{token}/resend/.
zapassina_set_document_deadline
Set a new deadline to sign, or clear it (clear_deadline true). A new deadline reopens an expired document. ZapAssina API: POST /docs/{token}/deadline/.
zapassina_update_signer
