Getting Started - Invoice Desk

Welcome to the Invoice Desk API! This guide will walk you through how to start using the API to programmatically manage invoices, clients, projects, and more.

Step 1: Create an Account

Visit invoicedesk.app and sign up for a free account.

Once you’ve completed the setup by creating your first company, you’ll be able to access API functionality tied to your account.

Step 2: Generate an API Key

After setup:

Go to Account Settings > API Access

Click Generate API Key

Your key is securely linked to your account and company. Keep it safe and do not expose it in frontend code.

Step 3: Make Your First API Call with curl

Base URL: https://api.invoicedesk.app/

Here’s a quick way to verify your API integration is working using curl.

Example: List Companies

Example: Create a Client

Example: Export an Invoice to PDF

🔐 Note: Replace YOUR_API_KEY, your-company-id, and invoice-id with real values from your account.
