Connect APIs now detect unsupported characters in email addresses before insertion into the PMS. If an unsupported email address is submitted, it is not stored in the PMS and the request returns HTTP 200 with a warning in the warnings array.

Affected endpoints: PUT /guests/{id}, POST /guests, POST /reservations, PUT /reservations/{id}, POST /groups, PUT /groups/{id}, POST /accounts, PUT /accounts/{id}

Example response (unsupported email address):

{
  "warnings": [
    {
      "message": "Unsupported characters detected in the email address. This email address will not be added to the PMS"
    }
  ]
}
