Documenso Install & Auth

Overview

Set up Documenso SDK and configure API authentication for document signing integration.

Prerequisites

• Node.js 18+ or Python 3.10+
• Package manager (npm, pnpm, yarn, pip, or uv)
• Documenso account (cloud or self-hosted)
• API key from Documenso dashboard

Instructions

Step 1: Install SDK

TypeScript/Node.js:

# npm
npm add @documenso/sdk-typescript

# pnpm
pnpm add @documenso/sdk-typescript

# yarn
yarn add @documenso/sdk-typescript

# bun
bun add @documenso/sdk-typescript

Python:

# pip
pip install documenso_sdk

# uv (recommended)
uv add documenso_sdk

# poetry
poetry add documenso_sdk

Step 2: Get API Key

1. Log into Documenso dashboard at https://app.documenso.com
2. Click your avatar in the top right corner
3. Select "User settings" (or "Team settings" for team APIs)
4. Navigate to "API tokens" tab
5. Click "Create API Key"
6. Copy the generated key (shown only once)

Step 3: Configure Authentication

# Set environment variable
export DOCUMENSO_API_KEY="your-api-key"

# Or create .env file
echo 'DOCUMENSO_API_KEY=your-api-key' >> .env

Step 4: Verify Connection

TypeScript:

import { Documenso } from "@documenso/sdk-typescript";

const documenso = new Documenso({
  apiKey: process.env.DOCUMENSO_API_KEY ?? "",
});

// Verify connection by listing documents
async function verifyConnection() {
  try {
    const documents = await documenso.documents.findV0({});
    console.log("Connection successful!");
    console.log(`Found ${documents.documents?.length ?? 0} documents`);
    return true;
  } catch (error) {
    console.error("Connection failed:", error);
    return false;
  }
}

verifyConnection();

Python:

import os
from documenso_sdk import Documenso

documenso = Documenso(
    api_key=os.environ.get("DOCUMENSO_API_KEY")
)

# Verify connection
try:
    documents = documenso.documents.find_v0()
    print(f"Connection successful! Found {len(documents.documents)} documents")
except Exception as e:
    print(f"Connection failed: {e}")

Output

• Installed SDK package in node_modules or site-packages
• Environment variable or .env file with API key
• Successful connection verification output

Error Handling
