Zoho Recruit to Supabase Data Migration

The client needed to move beyond Zoho Recruit's standard exports, which couldn't capture relational data like candidate-to-job associations, interview stages, notes, and custom module fields. They needed a solution built directly on the Zoho Recruit REST API, one that could handle OAuth authentication, pagination, rate limits, and attachments programmatically.

Working directly with the Zoho Recruit API, I designed a Supabase PostgreSQL schema preserving Zoho's original record IDs and relationships across candidates, job openings, clients, contacts, and applications, then built a migration script to extract candidate profiles, resumes, interviews, and custom fields. I rounded it out with an incremental synchronization process so new and updated Zoho records keep flowing into Supabase after the initial migration.

I gave the client a fully queryable, relational copy of their Zoho Recruit data in Supabase, cutting out manual exports and reducing data management overhead. The ongoing sync kept both systems aligned without repeated manual intervention, and I documented the source code so the client's team could maintain and extend the integration on their own.
