# Documenso plugin

> Create and manage Documenso signing envelopes, legacy documents and templates, recipients, fields, folders, attachments, downloads, and embed tokens through the documented v2 REST API.

Use **Documenso** through Corsair: one client, typed API calls.

Generate a team-scoped API token in Documenso Team Settings / API Tokens and store it as the Corsair `api_key`. Documenso expects the raw token in `Authorization` (no Bearer prefix). The current base URL is `/api/v2`; set `baseUrl` for staging or a self-hosted instance. HTTPS is required except for localhost loopback development URLs.

The OpenAPI reference still lists deprecated v2 `/document/*`, `/template/*`, and matching field/recipient routes. They are included here for migration compatibility and scheduled for removal on 1 March 2027; use `/envelope/*` operations for new integrations. The plugin does not implement v1, v2-beta, or webhooks.

PDF downloads return `{ kind: "binary", contentType, base64, size }` and are limited to 20 MiB per response. PDF uploads use `files: [{ filename, contentType, contentBase64 }]` or the legacy single `file` shape; they are capped at 16 MiB per file and 32 MiB total per request for bounded transport. These plugin-side limits are not Documenso plan limits.

Standard requests time out after 20 seconds; multipart uploads and PDF downloads use a bounded 120-second timeout so permitted transfers can complete on slower links.

**What you get:**

* 89 typed API operations

## Setup

**1. Install**

```bash npm theme={null}
npm install corsair @corsair-dev/documenso better-sqlite3
npm install --save-dev @types/better-sqlite3
```

```bash yarn theme={null}
yarn add corsair @corsair-dev/documenso better-sqlite3
yarn add --dev @types/better-sqlite3
```

```bash pnpm theme={null}
pnpm install corsair @corsair-dev/documenso better-sqlite3
pnpm install --save-dev @types/better-sqlite3
```

```bash bun theme={null}
bun add corsair @corsair-dev/documenso better-sqlite3
bun add --dev @types/better-sqlite3
```

**2. Add the plugin**

```ts corsair.ts theme={null}
import Database from 'better-sqlite3';
import { createCorsair } from 'corsair';
import { documenso } from '@corsair-dev/documenso';

export const corsair = createCorsair({
	plugins: [
		documenso(),
	],
	database: new Database('corsair.db'),
	kek: process.env.CORSAIR_KEK!,
	multiTenancy: true,
	hub: {
		projectApiKey: process.env.CORSAIR_API_KEY!,
		signingSecret: process.env.CORSAIR_SIGNING_SECRET!,
	},
});
```

With `multiTenancy: true`, scope calls with `corsair.withTenant(id)`. See [Quick start](https://docs.corsair.dev/quick-start.md) for KEK + Hub keys, and [Multi-tenancy](https://docs.corsair.dev/concepts/multi-tenancy.md) for account isolation.

**3. Choose authentication**

> [tab] API Key (Recommended)
>
> Store the Documenso API key before the first call: `pnpm corsair setup --plugin=documenso --tenant=acme api_key=<your-key>` (leave out `--tenant` without `multiTenancy`), or pass it as `key` in the plugin options. With Hub, each tenant enters their own key on the connect page. See [API key auth](https://docs.corsair.dev/concepts/api-key).
>
> ```ts theme={null}
> documenso()
> ```
>
> More: [API Key](https://docs.corsair.dev/concepts/api-key)

**4. Connect a tenant**

Mint a connect link and send the tenant to it. Hub hosts the page and delivers the result to your app — see [Connect / OAuth](https://docs.corsair.dev/management/connect).

```ts theme={null}
const { connectUrl } = await corsair.manage.connect.createLink({
	plugin: 'documenso',
	tenantId: 'acme',
});
// redirect the user's browser to connectUrl
```

## Example API calls

**List envelopes**

```ts theme={null}
const tenant = corsair.withTenant('acme');
await tenant.documenso.api.envelopes.find.get({ perPage: 1 });
```

**Update an envelope**

```ts theme={null}
const tenant = corsair.withTenant('acme');
await tenant.documenso.api.envelopes.update.post({ envelopeId: 'envelope_sample' });
```

See the full list on the [API](https://docs.corsair.dev/plugins/documenso/api.md) page.
