Error handling

Overview

As you might have read along these documents, most of the MobbIDAPI callbacks have an error as their last argument. This is the way MobbID let you know the reason why a process did not end successfully.

The possible error comes with the general structure as follows:

{
    "errorCode": "WRONG_PARAMETERS_ERROR",
    "errorDetails": "Some of the parameters are not valid"
}

where:

• errorCode: is a string and represents the specific code identifying the error.
• errorDetails: is a string and provides additional information or context about the error.

Error codes

The following table shows the possible error codes and their meaning:
