 When the person clicks **Create GitHub App**, GitHub redirects back to the `redirect_url` with a temporary `code` in a code parameter. For example:
 
-    https://example.com/callback?code=a180b1a3d263c81bc6441d7b990bae27d4c10679
+    https://example.com/redirect?code=a180b1a3d263c81bc6441d7b990bae27d4c10679
 
 If you provided a `state` parameter, you will also see that parameter in the `redirect_url`. For example:
 
-    https://example.com/callback?code=a180b1a3d263c81bc6441d7b990bae27d4c10679&state=abc123
+    https://example.com/redirect?code=a180b1a3d263c81bc6441d7b990bae27d4c10679&state=abc123
 
 #### 3. You exchange the temporary code to retrieve the app configuration
