Integration phase

Once contracts and terms and conditions (T&Cs) have been signed, you can start the integration process with our APIs. We will provide you with the test environment and support from our APIs team to facilitate a smooth and seamless integration. The integration timeline varies depending on the type, with some taking just a few days, while others may require more time.

Production deployment

When transitioning to the production phase, it is essential to verify the correctness of the API integration. This validation involves executing a set of tests, which are collaboratively conducted by both QA and development teams from both the customer and Circle K sides.
