Once you've passed all the acceptance tests using Grafton, you are ready to begin testing your live integration. On Manifold you will need to provide an Integration URL pointing to your hosted integration.
IMPORTANT: Once integrated and in production, you must be using Manifold's Master Public Signing Key to validate requests coming from the Manifold servers. Make sure to support running your integration without the Grafton master keys.
Manifold authentication libraries support this out-of-the-box.
