+# Get The Response Status From An Axios Error
+
+You can make API requests with [`axios`](https://github.com/axios/axios). If
+the request fails because of a 4xx or 5xx response, an error will be raised.
+The response to the request is stored on the error so that you can still access
+the details of the response in your error handling logic.
+
+Here is a snippet of code that details using async/await with `axios`. It wraps
+the call in a `try/catch` block.
+
+```javascript
+async function getCharacter(characterId) {
+  let response;
+
+  try {
+    response = await axios.get(
+      `https://rickandmortyapi.com/api/character/${characterId}`
+    );
+  } catch (e) {
+    response = e.response;
+  }
+
+  console.log(response.status);
+
+  // You can also access the response data
+  // console.log(response.data);
+}
+
+getCharacter(2);
+//=> 200
+
+getCharacter(2000);
+//=> 404
+```
+
+In the case of the second call that results in a 404 response, the `catch`
+block is executed. This pulls the `response` off the error (`e`).
+
+Just like the standard response, the response from the error contains `status`,
+`data`, `headers`, etc.
+
+This also works with a promise-based control flow.
