Some strategies perform additional validations on user data. It might be the useful information in case the user data is not valid.

Let’s look at an example ended conversation:

An example of a conversation snippet with identity validations performed on user data.
             "errors": [],
                   "nationalId": "02070803629"
                   "nationality": "PL"
                 "name": "CONSISTENCY_CHECK",
                 "result": "FAILED",
                 "details": {
                   "field": "PERSON_IDS_NATIONAL_ID",
                   "reason": "FORMAT_ERROR"

In the example, the result.identity.checks section is visible. This is a list of validations performed on user data. The following data may appear here:

  • name: the name of the validator

  • result: the result of the validation process. This field may contain one of the following values:

    • ACCEPTED - the validation was performed and the result is positive,

    • FAILED - the validation was performed and the result is negative,

    • ERROR - the validation was performed, but an unexpected error occurred

  • details: - validation process details. Details may have different properties depending on the validator

Available validators

Below is a list of currently available validators. Please note that the list of validators will be expanded over time. Some validators do not present the result if the result is positive.
