To test your integration without actually charging credit cards, you can use our Stage Environment at https://stage-go.wepay.com. Our Stage Environment is an exact copy of our Production Environment, except that credit cards and bank accounts do not actually get used.
To get started, you simply need to sign up at https://stage.wepay.com/register and register your application. You’ll be assigned a set of API keys unique to the Stage Environment, and you’ll need to update your endpoints accordingly: https://developer.wepay.com/docs/articles/api-endpoints
We also have test credit cards, bank accounts, and magic numbers available:
Please note that any and all testing must be done in our Stage Environment. Any test payments in our Production Environment that are not legitimate payments from a true payer to a true merchant/fundraiser may cause delays and other issues for your application.
