# Signature Requests

> Create, send, update, and manage signature requests; download files and signing links.

The Signature Requests API lets you build complete eSignature workflows — from creating and sending requests to tracking signer progress and downloading signed documents.

## Key concepts

* **Signature Request** — a document sent to one or more signers for legally-binding electronic signatures.
* **Signer** — a recipient who must review and sign the document. Each signer receives a unique signing link.
* **Signing Link** — a URL that opens the hosted signing experience for a specific signer (redirect flows).
* **Signing Session** — a short-lived `sign_url` for embedding the signing experience inline with the Embed Signing SDK.
* **Template** — a reusable document with pre-defined signature fields. Use `Send from Template` to create requests without re-uploading files each time.

## Typical workflow

1. **Send** a signature request with documents and signer details (or use a template).
2. **Deliver signing** to each signer — use [Create Signing Session](/tabs/api-reference/api/signature-requests/create-signing-session) for embedded signing, or [Get Signing Link](/tabs/api-reference/api/signature-requests/get-signing-link) for redirect flows.
3. **Monitor** the request status via the [Get Signature Request](/tabs/api-reference/api/signature-requests/get-signature-request) endpoint or [webhooks](/tabs/guides/webhooks/overview).
4. **Download** the signed agreement, Certificate of Completion (CoC), or merged PDF once all signers have completed.
