Gravity Forms / Contact Form 7 → HubSpot when the addon fails

Docs explain how to connect Gravity Forms to HubSpot or Contact Form 7 to HubSpot. They rarely cover what happens when the addon fails: silent drops, 429s, partial property writes, or consent checkboxes that never reach the CRM.

HostHob diagnoses those failure modes and, when needed, replaces the addon path with a queued server-side WordPress → HubSpot sync.

Common failure patterns

• Timeouts under campaign spikes (request dies before HubSpot responds)
• Validation errors on required HubSpot properties — form still “succeeds” on WP
• Duplicate contacts from missing dedupe keys
• Consent / marketing status not mapped to the right HubSpot fields
• Addon updates breaking after a HubSpot or WordPress release

Fix ladder

1. Confirm HubSpot private app scopes and property existence
2. Log every submission attempt + HubSpot response body
3. Add retries / queue for transient failures
4. If the addon cannot carry custom objects or audit needs — move to custom API

Proof: HubSpot–WordPress lead sync (replaced a brittle middleware path).
