We need an experienced HubSpot developer to build a webhook-based integration between Thinkific (our course platform) and HubSpot (our CRM) using Make.com as middleware.
The architecture is fully designed. We have a detailed 28-page implementation spec that defines every HubSpot property, Custom Object schema, Make.com scenario, and workflow. You are executing a defined build, not designing a solution from scratch.
What we're building:
A HubSpot Custom Object ("Enrollment") that tracks individual course enrollments associated with contacts — designed to scale to multiple courses over time
5 Make.com scenarios connecting Thinkific webhooks to HubSpot (enrollment events, course progress, course completion, Pro purchase/coupon redemption, and HubSpot form submission triggering Thinkific enrollment)
6 HubSpot-native workflows (welcome sequence triggers, stall detection, completion actions, coaching tracking, Pro onboarding, internal sales notifications)
Custom contact properties organized into property groups for relationship-level and organization-level data
What you'll receive from us:
Complete implementation spec document with property schemas, scenario flows, data mapping tables, webhook payload examples, and a testing checklist
Access to our HubSpot, Thinkific, and Make.com accounts
A responsive point of contact for questions
Required experience:
HubSpot Professional or Enterprise — specifically Custom Objects (creating them, building associations, writing Custom Object-based workflows). This is non-negotiable. If you haven't built Custom Object workflows before, this isn't the right project.
Make.com (or Integromat) — building webhook-triggered scenarios with conditional routing
Working with REST APIs and webhook payloads (Thinkific's API specifically is a plus, but not required)
HubSpot workflow automation (contact-based and Custom Object-based)
Deliverables:
1. All HubSpot custom properties and property groups created per spec
2. Enrollment Custom Object created with full property schema and contact association
3. Make.com scenarios built, tested, and running
4. HubSpot workflows configured and active
5. End-to-end testing completed per the checklist in our spec (approximately 20 test cases)
Brief handoff documentation noting any deviations from the spec or issues encountered
In your proposal, please answer these three questions:
Have you built HubSpot Custom Objects and Custom Object-based workflows before? If yes, briefly describe the use case.
Have you built Make.com scenarios that process webhooks and write to HubSpot? If yes, how many scenarios roughly?
What is your estimated timeline for this project assuming you receive a complete implementation spec on day one?
Short, specific answers are better than long generic ones. We'll share the full spec with shortlisted candidates before finalizing.
