Two-way sync
Changes in Workday instantly reflect in Supabase, and back. No stale data, no manual imports.
Map the fields once, and every write moves both ways in milliseconds. Supabase row inserts land in Workday, Workday updates land back in Supabase.
Trusted by fast-scaling teams, from YC startups to enterprise platform teams

Connects over SOAP Workday Web Services (WWS), a REST API, and Reports-as-a-Service (RaaS) endpoints for custom reports, mapped field-by-field into Supabase, with row-level audit and no backend of your own to run.
Every table maps to a Workday object both ways. Insert a row in Supabase and it lands in Workday; update a record there and Supabase reflects it back.
Polling, including transaction-log criteria on SOAP operations to fetch objects changed…. Stacksync polls efficiently so updates still land in Supabase within moments.
Standard objects and customers and invoices are both fair game. Stacksync's schema discovery maps fields automatically, no manual data dictionary.
Patterns a two-person team can ship in a week. Any table in Supabase maps to any object in Workday.
Changes in Workday instantly reflect in Supabase, and back. No stale data, no manual imports.
Sync Workday worker records into Supabase so IT and identity systems provision hires, transfers, and terminations automatically.
Replicate Workday worker, organization, and compensation data into Supabase for people analytics, without giving analysts Workday tenant access.
Push completed Workday payroll results into Supabase each pay cycle for finance reporting.
Import journal entries from Supabase-backed billing or expense systems into Workday Financials.
No custom ETL jobs, webhooks, or sync scripts to write and maintain. Map Supabase tables to Workday objects like Workers and Organizations once, and every write stays in sync from there on.
Changes in Supabase reach Workday in real time, and back. workers, organizations and positions stay consistent everywhere they live.
Your Supabase write-ahead log is read directly, while Workday is polled efficiently within its API limits, so sync keeps pace with live traffic without hammering your database or hitting rate limits.
OAuth your project and the system. Schemas read automatically.
Tables to objects, fields to fields. Transforms run inline.
Historical backfill, then continuous CDC both ways.
Row-level logs, latency and one-click replay.
One client, the same auth as your Supabase project. If you know the Supabase client, you already know this one.

Normally $1,000/mo. Yours at $0 during launch week.
Plus $100 in sync credits on the house. No card, no sales call, the same self-serve start you got with Supabase.

The integration layer is where compliance reviews stall. Row-level audit, residency and DPF certification for US, EU, UK and CH transfers, so procurement is a form, not a quarter.

Connects to your systems your way.
Stacksync watches your Supabase tables via CDC and Workday's API in real time. A write on either side maps to fields on the other and propagates in milliseconds, with row-level logs for every change.
Yes. Changes made in Supabase propagate to Workday and vice versa. One-way flows are also supported when a direction should stay read-only.
No. Authenticate both systems, pick objects and fields to map, and enable the sync. Most integrations go live in minutes with no infrastructure to manage.
Stacksync is SOC 2 Type II, ISO 27001, HIPAA, GDPR, CCPA and CSA STAR certified, and holds the EU-US, UK and Swiss Data Privacy Framework (DPF) certification. Data is encrypted in transit, with a zero-persistent-storage architecture: records aren't retained after a sync operation.
