Changelly Affiliate Program features a referral link, payment button, banners and customizable widget for every our regular user. These tools allow gaining the 50% revenue share for each transaction other users make via either of them.

But what’s in that for you, if you run a business and develop your own product? Changelly provides API for all crypto enthusiasts who run a project, whether it’s a cryptocurrency wallet or marketplace. Your users will be able to swap between cryptos right within the interface of your product. And you will get a revenue for each transaction performed this way.

Difference between API and Affiliate Program

Unlike the API, Affiliate tools represent an HTML source code you can integrate into your crypto/IT related blog, website or post on social media. Basically, this is a simple method to provide visitors with payment options and monetize the flow. These tools can be used by any individual who is registered on Changelly without prior notification.

The API, in turn, is a mechanism tightly integrated into the product interface that maintains exchange processes. It is designed mostly for service providers, such as cryptocurrency wallets, marketplaces or crowdfunding platforms.

Changelly’s API uses the same algorithms as the website, so your users don’t need to go to the website for exchanging crypto. Instead, they initiate a transaction and all manipulations related only on your service. The API acts as a hidden engine enabling your users to easily exchange their coins or make purchases.


Blockmarket is one of the crypto marketplaces that works with Changelly’s API. The marketplace has its native SYS token and works similarly to eBay, so you can buy goods here for SYS. The API integrated allows using any coin supported on Changelly itself that is automatically converted into SYS in a seamless way. Thus, the API payment options for Blockmarket users and gives additional benefits to the product team.

Your benefits from our API

Unlike Affiliate tools that provide 50% of our revenue, API commission fee is charged differently. You can set up any commission fee you find reasonable to charge your customers with.

To get this fee assigned to all the transactions to be made via our API, you’ll just need to contact our product team at providing them with the link to your service and specifying the fee percentage you suggest. It’s important to keep in mind that Changelly fee will be charged as well, so the full amount charged from your customers’ transactions will make your own customizable fee plus 0.5%, charged by Changelly.
