Ping-Pong Prevention and Guards

< 1 min read Updated Jun 6, 2026

The sync loop problem

With both outbound sync and inbound webhooks active, a loop can occur: WordPress pushes to GHL, GHL webhooks back to WordPress, WordPress pushes again. Without protection this continues indefinitely.

The 30-second inbound guard

When the plugin receives an inbound webhook for a contact, it sets a WordPress transient with a 30-second TTL keyed to that contact ID. During that window, outbound sync for the same contact is skipped.

You may see log entries labeled “skipped: inbound guard active” shortly after a webhook was received. This is normal, not an error.

The ContactCreate outbound guard

When the plugin creates a new WordPress user in response to a ContactCreate webhook, it suppresses the resulting user_register hook from firing an outbound sync, preventing the loop at the point of user creation.

No configuration needed

Both guards are always active. You do not need to configure anything.
