Dev drawer and Copy as cURL

The dev drawer shows the last several API calls the app has made and lets you copy any of them as a runnable cURL command. Handy when a screen doesn't behave, or when you want to reproduce a call outside the app.

What you'll do

• Open the dev drawer.
• Inspect a call's request and response.
• Copy any call as cURL.

Open the drawer

Three ways:

• Open the Settings dropdown in the top-right of the header and toggle Dev drawer. A check mark appears next to it while the drawer is open.
• Press Cmd+Shift+D on macOS or Ctrl+Shift+D on Windows/Linux.
• Add ?debug=1 to any URL.

What's inside

• A list of the most recent calls, each showing method, URL, status, and duration.
• Click a call to see the detail pane:
  • Request method, URL, and headers.
  • Request body.
  • Response status, headers, and body.
  • Timestamp.
  • A Copy as cURL button.

Copy as cURL

Click Copy as cURL on any call. The command is copied to your clipboard, ready to paste into a terminal.

For your safety, the copied command intentionally leaves out the session cookie. This means the copied command will not authenticate as you; if you need to reproduce authenticated behavior, use your own access token directly against the Meta API.

Good to know

• The buffer keeps the last several calls and is not persisted. Refreshing the page clears it.
• Only calls that go through the app's shared network layer show up here. Truly ad-hoc requests you make in the browser dev tools console will not.

Troubleshooting

• The keyboard shortcut does nothing, click on the page first so it has focus, then try again.
• A call you expected is missing, some calls (like some background health checks) may be filtered out. Interact with the page and check again.
• The copied cURL fails with an authentication error, that is expected. The command has no cookie by design. Reproduce the call with your own access token if needed.
