    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Check whether a web page's Meta Pixel (Facebook Pixel) works: cookie consent, duplicate events, event IDs, the ad click ID (fbclid -> _fbc) and signs of server-side tracking. A browser in the EU visits the page twice. Reuses a result from the last 24 hours unless recheck is true. Waits for the result up to wait_seconds (a check takes 20 to 60 seconds); if it is still running, call get_report later.

    Description, as the server wrote it
    Step-by-step guide (Markdown) for fixing a problem the check found, for the site's platform when one exists (otherwise the general version). With consent_tool, returns the guide for wiring the Meta Pixel to that consent tool instead. Guides exist for: meta.fires_before_consent, meta.not_firing_after_consent, meta.duplicate_pixel, meta.missing_event_id, meta.fbc_not_set, and general.server_side_not_detected (setting up the Conversions API).
