## Avenu API Release Notes 1.8.5

## Overview

### Input validation and sanitization for `customer onboarding` endpoint

This enhancement entails guard railing the input provided to the customer onboarding endpoint by enforcing size, format and mandatory restrictions to those parameters. As a corollary to this implementation, error response codes were also implemented that are now provided and present concise and specific feedback to the calling application/consumer about the restriction violated.

### Enhancement for fraud check payloads to map to compliance monitoring system

This enhancement surfaces the "comments" field that is returned and maps it to the correlating field in the compliance monitoring system, in order to provide more useful information for those working the compliance alerts.

Error codes have also been modified to provide more useful and specific details for why and error occurred. 

#### Error Codes

For Required, Size, and Format restrictions an error code may be returned for each field. Only one error code is returned per field each time in that order. For example, if `firstName` is >50 characters and has special characters, only the size restriction error code and message will be sent back **first** as:

```json
{
    "code": "CA3107",
    "message": "firstName: Invalid Length"
}
