# signatures.request

Ask someone to sign a document on a hosted page, and get the signing link to give them. kind contract: text is the agreement exactly as the shop wrote it (Doing Work never writes contract or legal wording). kind job_document: a stored job PDF (documents.list). The signer signs in, reads it, types their name and agrees to sign electronically. Agents can never sign.

| Who | Agents can call this |
| REST | `POST /v1/signatures` |

| Area | [Field work (checklists, forms, time, notes, change orders, subcontractors)](https://doingwork.work/docs/reference/#field-work-checklists-forms-time-notes-change-orders-subcontractors) |

## When to use it

Ask a customer, or someone in the shop, to sign a document: contract text you supply (for example a service agreement) or a PDF already stored on the job. signatures.request returns a sign_url on the hosted pages; send it to the signer yourself.

## What to tell the owner

Say what you did in plain words and what happens next.
