Use a field-appropriate test event and distinguish expected delayed events from delivery failures.","candidate_action":"Treat silence as a configuration or delivery-path question rather than an API error: identify whether the integration uses Instagram Platform, Instagram Graph API, or Instagram Messaging; confirm the selected object and field, required access/permissions and account or Page subscription; verify the HTTPS callback and challenge exchange; then observe signed POST delivery and return 200 OK promptly while deduplicating retries.","applicability":["Instagram Platform webhooks for a professional account, including Business Login for Instagram or Facebook Login for Business.","Instagram Graph API webhooks configured on the Instagram Graph API object, where the connected Page subscription requirement applies.","Instagram Messaging webhooks, where the documented permissions and multi-app subscription requirements apply."],"limitations":["The official pages expose different setup paths and are not interchangeable: account-level Instagram Platform subscription, Instagram Graph API Page subscription, and Instagram Messaging multi-app subscription must be checked according to the integration used.","The extracted Instagram field tables do not preserve every field-to-permission mapping, so verify the exact field's current permission requirement in the live Meta documentation and dashboard.","The Instagram Graph API webhook page states the Advanced Access prerequisite but does not provide callback acknowledgement, retry, or delivery-log details;
