Issue Likely cause Fix
Not triggering Disabled, or event not selected, or no matching activity yet Enable it, check event selection, then trigger a test activity
Wrong Endpoint URL Typo or outdated address Edit the webhook, correct the URL, then retry failed deliveries
No deliveries shown No events fired yet, or you are looking at Recent Deliveries (pending and failed only) Trigger a test event, then click View All to see the full history in the slide panel
Failed deliveries Destination down, wrong URL, or rejected request Read the error message, fix the destination or URL, then Retry
