+# Bearer token example
+
+If your API requires you to use a bearer token, you might want to use a script like this in the _Post Response_ scripting section:
+
+```javascript
+bru.setVar("token", res.body.access_token);
+```
+
+With this method, you can then use the `{{token}}` variable in other requests. Just select _Bearer Token_ in the _Auth_ tab and insert your variable.
+
+## String splitting
+
+If the authentication API does not deliver a JSON response but rather a singe string that looks like this `"Bearer FOOBAR"` you might want to split the string with a little something like this:
+
+```javascript
+bru.setVar("token", res.body.split(" ")[1]);
+```
