Understanding the 402 Error
Before we embark on our journey to mastering the 402 Error, it is crucial to have a clear understanding of what it actually is. The 402 Error, formally known as the "Payment Required" response status code, is a HTTP status code that indicates that the server refuses the request due to insufficient funds for the requested resource. This is most commonly encountered in e-commerce applications when a payment method is not accepted, or the client has insufficient funds in their account.
Table 1: Comparison of HTTP Status Codes
| HTTP Status Code | Meaning | Commonly Used |
|---|---|---|
| 200 OK | Request succeeded | Most successful requests |
| 404 Not Found | Requested resource is not found | Common navigation error |
| 402 Payment Required | Insufficient funds | E-commerce payment error |
| 500 Internal Server Error | Internal server error | Indicates that the server has encountered an unexpected condition that prevents it from fulfilling the request |
| 403 Forbidden | Access is denied | Client is authenticated but not authorized for the requested resource |
