Errors

In this section, you will find an overview of the errors you may receive from the endpoints of the Unico IDPay product.

---

Introduction

---

Unico IDPay uses conventional HTTP response codes to indicate the success or failure of an API request.

As a general rule:

• Codes in the 2xx range indicate success with the request.

• Codes in the 4xx range indicate incorrect or incomplete parameters (for example, a mandatory parameter was omitted, or an operation failed with third parties, etc.).

• Codes in the 5xx range indicate an error on the Unico IDPay product servers.

Unico IDPay also generates an error message and an error code formatted in JSON:

{
    "error": {
        "code": "40004",
        "description": "transaction id is invalid"
    }
}
