API Documentation

Use the Crater API to seamlessly embed invoicing and bill pay to your platform.

Getting started

To get started with our API, follow these steps:

Contact us to obtain sandbox API keys. These keys will give you access to a testing environment where you can experiment and develop your integration without affecting live data.
Familiarize yourself with the documentation on how to make requests for the specific resources you need to access. We provide comprehensive information on the available endpoints, request/response formats, authentication methods, and any required parameters.
Develop and test your integration using the sandbox environment. Ensure that your application interacts correctly with the API and meets your requirements.
When you're ready to deploy your integration in a production environment, reach out to us to obtain live API keys. These keys will enable access to the live data and resources of our API.

By following these steps, you can seamlessly transition from the development and testing phase to the live deployment of your application.
