anvil_create_etch_packet

Create an Etch e-signature packet (documents + signers). GraphQL mutation: createEtchPacket. IMPORTANT: isDraft defaults to true (a safe draft that sends nothing). Setting isDraft=false with real signers SENDS signature-request emails to those signers. Use isTest=true while developing.

destructive

Argument	Type	Description
data	object	Optional payload data used to pre-fill the packet's documents.
name*	string	Human-readable name for the packet.
files	array	Array of file/document objects (casts or uploads) to include. Passed straight through to Anvil.
isTest	boolean	Set true to create a test packet (no legal weight, no charge).
isDraft	boolean	Default true. When true, creates a draft and sends nothing. Set false to activate and email signers.
signers	array	Array of signer objects, e.g. [{ id, name, email, signerType, routingOrder, fields }]. Passed straight through to Anvil.
signatureEmailBody	string	Optional body text for the signature-request email.
