Zapier Integration with Webhook Capabilities

REQUEST_SUMMARY_V2 Problem - Current System: Presently, Spur may not have the capability to integrate with Zapier for webhook triggers, nor the option to use webhooks as both exit conditions and within automation flow nodes. Suggested Feature: Implement an integration with Zapier, enabling the use of webhooks to trigger actions in Spur's automation flows. Additionally, introduce the functionality to use webhooks as exit conditions and within various nodes of the automation flows. This would allow for more dynamic and responsive automation strategies, adapting to external events and data. Expected behavior - Expose clear integration setup and mapping flow - Support reliable sync with retries and visible failure states - Allow users to verify successful data movement end-to-end Business impact - Reduces manual operational effort for teams - Improves consistency and customer experience - Helps teams move faster with fewer support escalations Legacy category: New Feature
