The onboarding and payment linking process in sandbox matches the user experience in production. In order to facilitate testing in sandbox, we have provided to following credentials to be used.

​
Create a Test Account

  • Our sandbox user registration is designed to intake any phone number starting with 99 as a test user
  • The OTP for the test account will be last 6 digits of the test phone number
    • Ex. Phone number is 991-234-5678. OTP will be 345678
Note: Try different test numbers starting with +199 and any 8 digit number following that number. Do not use the example +19912345678 as it will fail and not process the payment.Use a random number following the above scheme as common numbers like 991-234-5678 are likely to have been used already
  • If you use a previously registered number, you will be considered an existing user and login via the phone number provided + OTP.
