# Formable API

> Embed e-signatures and collaborative document redlining directly into your product.

The Formable API lets you add document workflows to your application without building them from scratch. Upload a document once as a **template**, then use it to collect signatures or negotiate revisions between two parties — all through a REST API and embeddable URLs.

## What you can build

* **Embedded e-signature** — Send a document to a signer and drop the returned signing URL into an iframe. Retrieve the completed PDF when they're done.
* **Embedded redlining** — Let two parties (a disclosing and a receiving party) exchange revisions to a DOCX contract in turns, with counsel invited as needed.
* **Templates with prefilled fields** — Upload a document, place fields in the editor, then prefill values per signer at send time.

## How it works

<Steps>
  <Step title="Create a template">
    Upload a PDF or DOCX file with [Create a template](/api-reference/endpoint/create-template). Formable returns a `templateId` you'll reuse across requests.
  </Step>

  <Step title="Start a workflow">
    Create a [signature request](/api-reference/endpoint/create-signature-request) or a [redline request](/api-reference/endpoint/create-redline-request) from the template.
  </Step>

  <Step title="Generate a URL">
    Request an embeddable [signing URL](/api-reference/endpoint/create-signing-url) or [redline URL](/api-reference/endpoint/create-redline-url) and load it in an iframe.
  </Step>

  <Step title="Retrieve the result">
    Poll [events](/api-reference/endpoint/get-signature-request-events) or fetch the [signed envelope](/api-reference/endpoint/get-signed-envelope) once complete.
  </Step>
</Steps>
