Error Messages
When your receive a callback from Phaxio notifying you of a failure,
it will contain two values that can help you understand what went wrong:
an error_code and an error_type.
The error_type will give you a general idea of why the operation failed,
whereas the error_code describes the issue in more detail. Below we list the error_codes for the API,
segmented by their corresponding error_type.
The 5 Phaxio error types:
