Overview - Corsair

Use DocuSign through Corsair: one client, typed API calls, local DB sync. What you get:

340 typed API operations
15 synced entities (accounts, brands, bulkSendLists, connectConfigurations, contacts, customTabs, and 9 more) for fast .search() / .list()

Setup

Install

npm install corsair @corsair-dev/docusign

yarn add corsair @corsair-dev/docusign

pnpm install corsair @corsair-dev/docusign

bun add corsair @corsair-dev/docusign

Add the plugin

corsair.ts

import Database from 'better-sqlite3';
import { createCorsair } from 'corsair';
import { docusign } from '@corsair-dev/docusign';

export const corsair = createCorsair({
	plugins: [
		docusign({
			authType: 'oauth_2',
		}),
	],
	database: new Database('corsair.db'),
	kek: process.env.CORSAIR_KEK!,
	hub: {
		projectApiKey: process.env.CORSAIR_API_KEY!,
		signingSecret: process.env.CORSAIR_SIGNING_SECRET!,
	},
});

Multi-tenancy is the default — scope calls with corsair.withTenant(id). See Quick start for KEK + Hub keys, and Multi-tenancy for account isolation.

Choose authentication

OAuth 2.0 (Recommended)

Open hub.corsair.dev, navigate to your project, and enter the client ID and client secret from your DocuSign OAuth app.

docusign({
	authType: 'oauth_2',
})

More: OAuth 2.0

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.

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

Example API calls

Get an envelope

const tenant = corsair.withTenant('acme');
await tenant.docusign.api.getEnvelope({ envelopeId: '3a1b2c4d-0000-1111-2222-333344445555' });

Send an envelope from a template

const tenant = corsair.withTenant('acme');
await tenant.docusign.api.createEnvelope({
	emailSubject: 'Please sign the agreement',
	templateId: '7f6e5d4c-0000-1111-2222-333344445555',
	templateRoles: [{ email: 'jane@example.com', name: 'Jane Doe', roleName: 'Signer' }],
});

See the full list on the API page.

Query synced data

Search envelopes synced from earlier getEnvelope calls.

const tenant = corsair.withTenant('acme');
const rows = await tenant.docusign.db.envelopes.search({
	data: {},
	limit: 50,
});

Synced entities: accounts, brands, bulkSendLists, connectConfigurations, contacts, customTabs, documents, envelopes, groups, permissionProfiles, recipients, signingGroups, templates, users, workspaces. See Database for filters and operators.
