With our API-based crypto payment infrastructure developed for your business, you can securely and quickly accept payments in USDT (Tether) via the TRC20 network. The integration process is extremely simple, allowing you to modernize your digital payment systems and step into the world of cryptocurrency. By reviewing our API documentation, you can integrate the system in just a few steps and start accepting USDT payments right away.
You can register for the system in the Join Us section of the https://www.tetherpays.com URL. When you register, you will receive a verification email and a Google Authenticator code. The Google Authenticator code is also displayed in the information warning that appears when you register with the system. To use the Google Authenticator code, you will need to download the Google Authenticator application to your mobile device, and you will be able to create a key by entering the code we sent you from the email into the application. You will be able to use this key value to log in to the system. Please note that your account must first be approved by the system administrators.
When you log in to the system, an API Key will be automatically defined for you. You can find the API key value under My Profile menu. When using the API, simply add a header called api-key to the header section of each request and enter your API key as the value.
You can make payment transactions with active cryptocurrencies in our system. Payment transactions cannot be made with any cryptocurrency that is not available for use with us. You can see which cryptocurrencies you can use in the service below.
