Creates an envelope with its signers and files and publishes it in one request, so invitations go out right away. Files are base64-encoded PDF or Word (.pdf, .docx) files. The whole request body may be at most 50 MB, so the base64 files can total about three quarters of that; for larger files use Upload Content. To build an envelope step by step or upload files as multipart, use Create Envelope, Create Signer, Upload Content and Publish Envelope instead. If validation fails, nothing is created; if a later step fails, the created envelope is deleted. Like Publish Envelope, it counts toward the team's e-sign usage and can fail with 402 on a free plan.
