The WPForms Webhooks addon POSTs entry payloads to one or more configured endpoints after submission, then logs the response code and headers back onto the entry via wpforms_entry_meta. Useful, until the team wants to know which endpoint is failing, how often, and on which form. The default Entries screen lists rows, the WordPress error log buries the failures, and there is no aggregate view of the outbound surface anywhere in the admin.

SleekView Charts reads wpforms_entries directly, joins wpforms for readable form names, and pivots webhook meta keys like _webhook_url, _webhook_status, and _webhook_response_code so each delivery becomes a row with proper columns. Count by status, group by URL, slice by form, and trend by date for daily delivery volume. The same indexed queries powering the entries screen stay fast on hundreds of thousands of deliveries.

Charts share the dataset and filters with Table view, so jumping from a 5xx-rate KPI to the failing entry rows is one tab. The Webhooks addon already writes everything you need into entry meta, so the dashboard is configuration, not custom logging.

WPForms Webhooks is the integration backbone of a lot of WordPress sites because it shuttles entry data to downstream systems without writing PHP. The trade-off is silence. When an endpoint starts returning 5xx, the only signal is buried in wpforms_entry_meta on individual entries, and the WordPress error log if PHP throws.

Integration teams want a Pie of 2xx versus 5xx by endpoint. Operations wants daily delivery volume to spot odd spikes. Form admins want to know which endpoint stopped working before customers do.

None of these are exotic analyses, they are response codes the addon already logs on every attempt. SleekView Charts surfaces them as configurable cards on the same entries table the admin already uses, so webhook health becomes a saved dashboard instead of a grep through error logs at incident time.
