Welcome to API Explorer!

Explore and make API requests and prototype products. You can test and try out all of our endpoints. All we ask is that you be mindful that the environment is shared. Be sure to avoid storing proprietary information and please be considerate of usage (e.g. infinite loops). If you need help, or are interested in developing something specific on the Marqeta Open API Platform, don’t hesitate to get in touch with someone on our team.
