Exchange API

What is Changelly Exchange API?

Copy link

Changelly API enables interactions between Changelly and external applications that use the Changelly exchange feature. The API is tightly integrated into the product interface and uses the same algorithms as the Changelly website. Hence, users of the outside service don’t need to leave it for the Changelly website to exchange some crypto.

The API is designed mostly for service providers such as cryptocurrency wallets, marketplaces, or crowdfunding platforms. Changelly API can be used for both web services and mobile applications.
