How References Are Organised

Reference files live in two subdirectories under references/:

• references/embed/ — Embed UI components (signing forms, template builder). Each file is self-contained — load only the ones matching the user's stack.
• references/api/ — REST API endpoints and webhooks. One file per endpoint/webhook with parameters, schemas, code examples, and response samples.

Embed UI Components

Component	Tag	Purpose	JWT
Signing Form	<docuseal-form>	Embed document signing UI into a page	optional
Form Builder	<docuseal-builder>	Embed a full template/document builder	required

Each component ships in four frontend implementations: JavaScript / React / Vue / Angular.

Signing Form (<docuseal-form>)

• JavaScript / HTML → references/embed/signing-form-js.md
• React → references/embed/signing-form-react.md
• Vue → references/embed/signing-form-vue.md
• Angular → references/embed/signing-form-angular.md
• Mobile (Android/iOS/React Native/Flutter via WebView) → references/embed/signing-form-mobile-integration.md

Form Builder (<docuseal-builder>)

• JavaScript / HTML → references/embed/form-builder-js.md
• React → references/embed/form-builder-react.md
• Vue → references/embed/form-builder-vue.md
• Angular → references/embed/form-builder-angular.md

After loading the main component reference, follow a link from its ## Guides section for step-by-step walkthroughs.

Cross-cutting

• JWT token generation — Form Builder (Node/TypeScript/Ruby/Python/PHP/Java/C#/Go) → references/embed/form-builder-jwt-token.md
• JWT token generation — Signing Form completed/preview mode → references/embed/signing-form-completed-preview-jwt-token.md
• EU Cloud / self-hosted host configuration — Signing Form → references/embed/signing-form-hosts.md
• EU Cloud / self-hosted host configuration — Form Builder → references/embed/form-builder-hosts.md
• Custom CSS theming — Signing Form (dark theme reference) → references/embed/signing-form-custom-css.md
• Custom CSS theming — Form Builder (dark theme reference) → references/embed/form-builder-custom-css.md
• Signing Form security recommendations → references/embed/signing-form-security-recommendations.md
• Form Builder security recommendations → references/embed/form-builder-security-recommendations.md

Common Embed Mistakes

#	Mistake	Fix
1	Generating JWT in the browser	JWT must be signed on the backend — the API key must never ship to the client. See form-builder-jwt-token.md / signing-form-completed-preview-jwt-token.md.
2	Passing the API key as data-token	data-token is a JWT signed with the API key, not the key itself.
3	Missing host/data-host on EU or self-hosted	Set data-host="cdn.docuseal.eu" for EU Cloud or your own hostname for self-hosted. See signing-form-hosts.md / form-builder-hosts.md.
4	Confusing /d/{slug} vs /s/{slug}	/d/{slug} is the template URL (single-party templates). /s/{slug} is an individual signer URL created via the /submissions API.
5	Multi-party template via data-src URL	Templates with multiple signing parties must be initiated via the /submissions API — the direct /d/{slug} URL only works for single-party templates.
6	camelCase props in HTML	The web component uses data-* kebab-case attributes. Only React/Vue/Angular use camelCase props.
7	Expecting a native mobile SDK	None exists. Embed via WebView — see signing-form-mobile-integration.md.
8	Passing customCss as a stylesheet link	customCss / data-custom-css takes a CSS string, not a URL. See signing-form-custom-css.md / form-builder-custom-css.md.
9	Embedding signing forms behind enumerable URLs	DocuSeal slugs are random, but an embedding page like https://yourapp.com/contracts/123/sign lets an attacker iterate integer IDs to reach other users' signing forms. Put the DocuSeal slug or a UUID in your URL, or require auth on the embedding page. See signing-form-security-recommendations.md.
10	Exposing the Form Builder without auth	The page that renders <docuseal-builder> must be gated by your app's authentication. The JWT-issuing endpoint must verify the requesting user owns the template referenced by external_id. Otherwise any logged-in user can edit any template. See form-builder-security-recommendations.md.
11	Acting on client-side completed events	Browser events can be forged. Drive state changes from form.completed webhooks with HMAC verification, not from <docuseal-form> JavaScript callbacks. See signing-form-security-recommendations.md.

REST API

Authentication

All requests require an API key passed in the X-Auth-Token header:

X-Auth-Token: YOUR_API_KEY

Get your API key: https://console.docuseal.com/api

Base URLs

Environment	Base URL
Global Cloud	https://api.docuseal.com
EU Cloud	https://api.docuseal.eu
Self-hosted	https://docuseal.yourdomain.com/api

API Client SDKs

Official SDK libraries wrap the REST API and handle authentication, request building, and response parsing. Prefer SDKs over raw HTTP when the user's language has one.

Language	Package	Install
JavaScript / TypeScript	@docuseal/api	npm install @docuseal/api
Python	docuseal	pip install docuseal
Ruby	docuseal	gem install docuseal
PHP	docusealco/docuseal	composer require docusealco/docuseal

SDK usage examples are included in each endpoint reference file below (marked with "SDK" in the heading).

Endpoints

Templates

• GET /templates — List all templates
• GET /templates/{id} — Get a template
• DELETE /templates/{id} — Archive a template
• PUT /templates/{id} — Update a template
• PUT /templates/{id}/documents — Update template documents
• POST /templates/{id}/clone — Clone a template
• POST /templates/html — Create a template from HTML

• GET /submissions/{id}/documents — Get submission documents
• DELETE /submissions/{id} — Archive a submission
• PUT /submissions/{id} — Update a submission
• POST /submissions/emails — Create submissions from emails

• POST /submissions/docx — Create a submission from DOCX
• POST /submissions/html — Create a submission from HTML
• POST /submissions — Create a submission

Submitters

• GET /submitters/{id} — Get a submitter
• PUT /submitters/{id} — Update a submitter
• GET /submitters — List all submitters

Webhooks

Configure webhook URL: https://console.docuseal.com/webhooks

Common API Patterns

1. Send a document for signing: create a template (or use existing) → POST /submissions with submitter emails → submitters receive signing links
2. Embed signing in your app: create submission with send_email: false → use returned slug with <docuseal-form> (see Embed UI Components above)
3. Pre-fill and auto-sign: POST /submissions with fields[].default_value and completed: true
4. Track completion: poll GET /submissions/{id} or configure webhooks for form.completed
5. Download signed documents: GET /submissions/{id}/documents returns PDF URLs

Quick Decision Flow

1. Embedding a component? → Signing Form or Form Builder → load from references/embed/.
2. Making API calls? → Check if the user's language has an SDK (JS/TS, Python, Ruby, PHP) and prefer it over raw HTTP. Load the matching endpoint from references/api/.
3. How-to question about embed? Follow links from the component reference's ## Guides section.
4. Mobile? Load references/embed/signing-form-mobile-integration.md.
5. JWT needed? Always for Form Builder — load references/embed/form-builder-jwt-token.md. For Signing Form only when using data-token (preview/completed mode) — load references/embed/signing-form-completed-preview-jwt-token.md.
6. Not on docuseal.com? Load references/embed/signing-form-hosts.md or references/embed/form-builder-hosts.md depending on the component.
7. Custom theme? Load references/embed/signing-form-custom-css.md or references/embed/form-builder-custom-css.md depending on the component.
8. Auth, URL handling, webhook verification, or any security-sensitive embedding? Load references/embed/signing-form-security-recommendations.md or references/embed/form-builder-security-recommendations.md depending on the component.
9. CLI commands? Load the sibling docuseal-cli skill from this same repo.
