Each webhook delivery is logged. 4. **Inspect and replay failures** (you). Check delivery status and replay a failed webhook after your endpoint is ready. ## Connect the tools you use today. Booking connections, events, and the API move SetLuca data into your existing workflow. HubSpot and GoHighLevel connections are still in progress. ### Your own tools, through webhooks for now HubSpot and GoHighLevel connections are in progress. Until they ship, signed webhooks or the REST API carry leads and confirmed call outcomes wherever you keep them. - Signed events from SetLuca - REST API for custom workflows - MCP for connected AI assistants ### Booking on the calendar you use Connect Calendly, Cal.com, or Google Calendar, or give SetLuca a manual booking link. SetLuca offers available times and keeps the booking on the lead. - Calendly and Cal.com - Google Calendar - Manual booking link ### Webhooks that verify and replay Subscribe to SetLuca events such as a new lead or a booked call. Each delivery is signed, logged, and available for replay if your endpoint fails. - Signed deliveries - Delivery log with status for each attempt - Replay failed deliveries ## Three useful connections. ### A qualified lead for your own tools Your team wants qualified leads in its existing system. Use a signed webhook or the REST API to pass the lead. HubSpot and GoHighLevel connections are in progress. ### A call on the calendar A lead agrees to talk and needs a real open time. SetLuca offers times from Calendly, Cal.com, or Google Calendar, or shares your manual booking link. ### A webhook that needs replay Your endpoint is unavailable when an event is sent. The delivery log records the failure so you can inspect and replay it after fixing the endpoint. ## From manual updates to events you can route. ### Manual handoff - Leads wait for someone to copy them into another tool - A failed endpoint leaves no clear handoff - Booking links live in a separate workflow ### Connected workflow - Signed webhooks and the REST API route events - A delivery log shows failures and lets you replay them - SetLuca uses your supported calendar or manual booking link ## What connects today. | Connection | What moves | How it connects | | --- | --- | --- | | Calendly | Bookings and changes | OAuth | | Cal.com | Bookings and changes | OAuth | | Google Calendar | Availability and booked events | OAuth | | Manual booking link | A link to your booking page | Add your link | | Stripe | Payment events | Connect Stripe | | Signed webhooks | Subscribed SetLuca events | Create a subscription | | REST API | Scoped reads and actions | Developer API key | | MCP server | Scoped API tools | Developer API key | HubSpot, GoHighLevel (including its calendar), and iClosed connections are in progress, not available yet. ## Questions about connections. ### What happens when a webhook endpoint is down? The delivery attempt is logged. Once the endpoint is healthy, inspect the failure and replay it from the delivery panel. ### Does a rescheduled call update in SetLuca? A booking change from a supported calendar updates the lead so the next step uses the latest call time. ### Can I connect HubSpot, GoHighLevel, or iClosed now?

No for supported calendars: you authorize Calendly, Cal.com, or Google Calendar in the app, or add a manual booking link. A webhook subscription needs an endpoint URL, and building against the REST API takes developer work. Each webhook delivery is signed and logged, so whoever builds it can check what arrived. ### What happens if a webhook delivery fails? The delivery log records each attempt and its status. You can inspect a failed delivery and replay it after fixing your endpoint, so a lead or booked call that didn't arrive isn't lost. Every delivery is signed, which lets your endpoint confirm the event came from SetLuca before acting on it. ### Does SetLuca work with HubSpot or GoHighLevel? Not yet. HubSpot and GoHighLevel connections are in progress and not available today. Until they ship, signed webhooks or the REST API can carry qualified leads and confirmed call outcomes to your own tools, wherever you keep them. The GoHighLevel calendar and iClosed connections are in progress too. ### Which calendars can I connect? Calendly, Cal.com, and Google Calendar are available, and you authorize them in the app. You can also use a manual booking link if you schedule somewhere else. SetLuca offers available times from the calendar you connect and keeps the booking on the lead. GoHighLevel calendar and iClosed connections are in progress. ### Which plans include integrations?
