Welcome to the Crunch Developer Portal. Crunch provides a combination of expert advice and slick, powerful, and easy-to-use accountancy software developed in-house, making lives easier for thousands of freelancers, contractors, and small businesses in the U.K. Crunch has won an array of prestigious national awards.
Over the past few years we’ve been undergoing a significant rebuild of our software, moving over to a microservice based architecture and enhancing features as we go. This is all running on kubernetes which allows us to deliver new features to our clients much faster and with more reliability than we ever could before. We are now building on this momentum by rebuilding our public API. Crunch has provided a public API for over 10 years but as our infrastructure has changed and standards have moved on we wanted to bring these new benefits to developers wanting to build on the Crunch platform.
Our API is open to third-party and independent developers who want to build their own apps and integrations on the Crunch platform.
You can use the API whether you’re on a Crunch Pro or Premium plan, or using Crunch Free. If you don’t have a Crunch account yet, you can sign up for Crunch Free at no cost.
To find out what you can build, browse the API documentation, where you’ll find the available APIs, their endpoints and how to authenticate.
