Sandbox

The sandbox environment can be used to simulate and test a variety of scenarios you can incur in while using Teller without having to use real bank accounts.

Use the sandbox environment by initializing Teller Connect with the environment property set to sandbox.

Enrollments

Specific enrollment flows are triggered using a combination of the login credentials entered in Teller Connect after selecting an institution. In the sandbox environment, all institutions behave identically.

The valid login password is always password so if you want to simulate a bad credentials flow, all you need to do is provide a different value.

Username Values

  • Name
    username
    Type
    Description

    Leads to an immediate successful enrollment.

  • Name
    otp
    Type
    Description

    Will follow an OTP MFA flow whereby the user will be asked to select a contact to send an OTP code. The correct code is 0000

  • Name
    challenge
    Type
    Description

    Triggers a knowledge-based MFA flow where the end-user is asked their favorite color. Your favorite color is blue.

  • Name
    disconnected
    Type
    Description

    Results in a successful enrollment that will immediately disconnect upon the first request made to get data from it. Alternatively you can use any of the enrollment status reasons as usernames (e.g. account_locked).

Payments

Sandbox payment flows are determined by the memo value that is used when issuing the create payment request. To get a payment that is immediately successful and does not require user intervention use any value (or none at all) that does not appear in the following list.

Memo Values

  • Name
    otp
    Type
    Description

    The create payment response will contain a connect_token that you can use to initialize Teller Connect and perform an OTP MFA flow whereby the user will be asked to select a contact to send an OTP code. The correct code is 0000.

  • Name
    otp_error
    Type
    Description

    This behaves similarly to the otp value but results in an error when the correct OTP code (0000) is used, simulating a failure from the financial institution. This failure can be observed with Teller Connect's onFailure hook.
