How to Setup

  1. Go to the Settings page.
  1. In the "API Keys" section, click New API Key.
Now you have an API key and are ready to start invoicing!

The API is rate-limited. With almost every use case this should not be an issue.
If an API call does trigger rate limiting then we will respond with a 429 status code to let you know to try generating your invoice again later.
If you frequently run into these limits then you might also consider using our paid service at
