In Direct mode, since you are onboarded in each bank with your TPP status, you can use the sandbox of banks by setting the sandbox field to true in the configuration. The connector will use the right configuration to reach the sandbox whenever you set the sandbox flag to true.

In Gateway mode, you are not registered in banks and you don't need to, we have done it. Hence you don't have sandbox credentials and you cannot use the sandbox of the banks.

Will it be in Direct mode or in Gateway, we have a connector to the powerful and incredible tool: MockBank,

We provide sample data to test simple scenarii of your product. You'll find more details below.

To be able to tests all uses cases (payment failure due to lack of funds, negative balances, etc), you'll have to register with MockBank and create your own test set. You can reach them here: [email protected]

Technical Implementation

You have to use connector id -1

Your Docker container (Direct mode or Gateway Mode) must run in production mode, set"sandbox":false in the config.json file.

The "user" must be passed in the request in the field AdditionalPropertiesRequested like:

  "additionalProperties": {
    "username": "[email protected]",
    "useRedirectSCA": "Y"

Note that there is another additional field, useRedirectSCA, that allows you to use embedded and decoupled flows.
useRedirectSCA can be Y (yes) or N (no). "Y" (Yes) means use redirect approach.

When you supply "N" (No), you will be prompted to select the approach method that you have defined in the configuration of your Mockbank account > Test customer > edit one customer > SCA Method.

It can be an embedded, like a SMS simulation by entering a fixed value that you have defined or a decoupled that has to be validated in the Mockbank's interface. So you'll need to access to your mockbank account to validate the decoupled and also for embedded.

Please check the AIS and PIS options end-points.
