Flow Hybrid Input Validation

Flow does as much as possible to ensure the user data it helps you collect and verify is clean and standardized. If you're using the fully managed Flow embed product then you don't need to worry about the validations described below. If you're using Flow Hybrid and submiting data via API, you will need to match the formatting and standardization requirements described below.

To help with development, we also provide a JSON file containing the same validation rules:

ID Numbers

Flow's Lightning Verification will automatically collect, validate, and verify any of the following ID numbers for countries that you've enabled in the Flow Editor.

If you are separately collecting ID numbers outside of Flow, or if you have existing customer data you're looking to import into Flow, you can submit this data to Flow's API programmatically.

The table below lists each ID number that Flow supports. The API type is a unique identifier that you should provide via API via the id_number.type field.

ID Numbers submitted via API should be stripped of any formatting characters like spaces, periods, and dashes. The table below also includes the exact regular expressions we use to decide whether a given ID Number is well formed and valid for that region's ID type.

Input Validation by Country

Address standards vary by country. Some countries do not support postal code or subdivision (the equivalent of "state" or "province" depending on the region). In other countries, postal code and/or subdivision is valid in a sense, but superfluous and not typically collected in native forms.

Separately, variations in identity data coverage mean that collection of "ID Number" is a required part of Lightning Verification in some countries, optional (configured in the Flow Editor) for other countries, and not supported in countries that do not support Lightning at all.

This regional variation is reflected in the table below.

The labels for each input field below correspond to the following input validations:

  • address.postal_code and address.subdivision

    • Required - If address is provided as part of the request, this field must always be present

    • Not Accepted - If address is provided as part of the request, this field must be omitted. Specifically, the key should be omitted from the address object (as opposed to the key being present with a null value)

  • id_number

    • Required - If id_number is not provided for this country, kyc_check will treat the Flow Session as having incomplete data and will require user interaction with the Flow modal in order to collect id_number

    • Optional - If id_number is not provided for this country and your Flow Template is configured to not collect ID numbers for this country then Flow will automatically run the kyc_check step without any user interaction as long as all other required input fields are provided. Similar to the address fields, the API requires you omit the id_number key entirely if you are not providing ID number data

    • Not Accepted - ID number verification is not supported for this country and the id_number field should always be omitted from API requests
