Why teams connect Resend and Workday
Connect the financial records in Workday with the work happening in Resend, so both stay current without exports or copy-paste.
Workday holds the financial truth: who the customers are, what they were billed, what they paid. Resend is where part of the day-to-day work happens, and that work often involves the same customers and transactions. Without a live connection, the two drift apart, and people end up answering questions from stale copies.
Stacksync keeps Time Off and Absence, Payroll Results, Suppliers, Customers and Invoices in Workday and Emails, Contacts, Audiences, Broadcasts in Resend in sync, bi-directionally and in real time. Whatever records Resend keeps and whatever events it produces, the overlap with Workday is mapped field by field, and a change on either side shows up on the other within seconds.
There is no middleware to build, no API rate limits to babysit, and no nightly job that leaves the morning running on yesterday's data.
Common use cases
- Push completed payroll results into a finance system or data warehouse each pay cycle.
- Import journal entries from external billing or expense systems into Workday Financials.
- Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.
- Trigger transactional sends when a row changes in an operational database, such as an order status update.
Where Resend tracks people or companies: one identity
A customer's details updated in either system update the other, so finance and the rest of the business stop maintaining two versions of the same customer.
Where Resend handles customer conversations: billing context in view
Front-line teams see invoice and payment status from Workday next to the customer they are helping, without logging into the finance system.
Where Resend collects payments or triggers charges: events land in Workday
Payment and charge activity flows into Workday as it happens, so the books reflect reality without manual reconciliation.

FAQ
Resend and Workday integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Resend and Workday: authenticate both systems, choose the objects to sync (such as Resend's Broadcasts and Domains), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Resend: REST API. Authentication: API key (Bearer token). Workday: SOAP Workday Web Services (WWS), a REST API, and Reports-as-a-Service (RaaS) endpoints for custom reports. Authentication: OAuth 2.0 for the REST API; integration system users with WS-Security or certificate-based auth for SOAP. Stacksync manages authentication, retries, and rate limits on both sides.
-
Workday: Workday is a multi-tenant SaaS where each tenant's configuration differs and web services are versioned, so integrations pin a WWS version and upgrade deliberately. Resend: The send endpoint supports idempotency keys, which matters when a sync pipeline retries requests. Stacksync's field mapping accounts for these differences between Resend and Workday without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Resend and Workday records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Resend and Workday connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Resend–Workday integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Resend and Workday. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
