Error handling strategies

1. Check HTTP Status Codes:

Use the status_code property of the response to identify errors.

Handle specific error codes accordingly.

2. Parse Error Messages:

Examine the error message in the response body for more details.

Use the error message to provide informative feedback to the user.

3.Retry Failed Requests:

Implement retry logic with exponential backoff to handle transient errors.

Avoid excessive retries to prevent overloading the server.

4.Log Errors:

Log errors to a log file or a centralized logging service for analysis and debugging.

Include relevant information such as timestamps, error messages, and request/response details.


    const myHeaders = new Headers();
myHeaders.append("token", "TlAWiePV51isvfuRZEHuCOW1ZDBeDHep2rnosIXHRVGvMwyFTMJZUVCeIneQJJ0h");
myHeaders.append("Content-Type", "application/json");

const raw = JSON.stringify({
  "customerId": "49438567-bc45-494c-b57d-80b41f193de7",
  "currency": "kes",
  "channel": "fiat"
});

const requestOptions = {
  method: "POST",
  headers: myHeaders,
  body: raw,
  redirect: "follow"
};

fetch("https://api.switch.tulupay.com/customer/add-account", requestOptions)
  .then((response) => response.text())
  .then((result) => console.log(result))
  .catch((error) => console.error(error));

    }

By implementing robust error handling, you can improve the reliability and user experience of your application.
