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.
