Testing Credit Card Purchases

Developers can use this documentation to test various credit card scenarios.

Card Purchases

Coinflow provides a set of test credit cards that can be used to test a purchase on sandbox. You may use any CVV, address, name, and future expiration date with the below numbers to simulate a successful purchase. To simulate a failed purchase, set the card zipcode to 99999. To simulate a rejected chargeback protection decision, set the card zipcode to 00000.

Testing on Production

When testing in production it is important to adhere to the following guidelines:

  1. Totals for testing transactions being $2+ per transaction
  2. Not more than 1 purchase by same card in a 15 minute increment
  3. Not more than 3 test transactions per card in a day

Failure to follow these guidelines could result in your production account being suspended.
