# PixelSign

> PixelSign is an e-signature API. Your app creates envelopes (PDF or HTML documents, signers, and fields) with one multipart request; PixelSign emails signers or you embed signing; you get signed webhooks and download the signed PDFs and certificate. Every organization has a live mode and a test mode with developer tools: simulated signers, magic test addresses, time travel, captured email, local webhook forwarding (`pixelsign listen`), and a dry-run preview of envelope create.

- API base URL: https://api.sign.pixelservicing.com
- Authentication: `Authorization: Bearer psk_live_…` or `psk_test_…` (keys are created in the dashboard at https://sign.pixelservicing.com)
- Every response has `X-Request-Id`; every error has a stable `code` and, for request problems, `errors[]` with JSON paths.
