To use the plugin, you need to register as a merchant in Sheepy here and verify your account to access the production environment.
Download the plugin by clicking the Download button. You will get an archive file with the plugin.
Upload the contents of the plugin archive to your WHMCS installation so the files are placed under modules/gateways. Then activate Sheepy from Setup -> Payments -> Payment Gateways.
Log in to your Sheepy dashboard and generate the API credentials required to connect your WHMCS installation.
Open the Sheepy payment gateway settings in WHMCS, enter your API credentials, and save the configuration. Your customers can now pay invoices using cryptocurrencies and stablecoins supported by Sheepy.
