Why teams connect Oracle Fusion Cloud HCM and SendGrid

Keep the people, teams, and status that SendGrid and Oracle Fusion Cloud HCM share aligned in real time, so a hire, role change, or departure recorded in one reaches the other within seconds.

Each tool in SendGrid keeps its own list of who can use it: users, members, or agents, along with the team they sit on and whether they are still active. Oracle Fusion Cloud HCM is the authoritative record of the same people as employees, with their department, manager, and employment status. When those two are connected only by manual account admin or a periodic export, the work tools drift: new hires wait days for access, team and manager changes never catch up, and people who have left keep standing accounts.

Stacksync syncs List, Segments, Categories, Senders in SendGrid with Workers (publicWorkers), Assignments, Jobs, Positions in Oracle Fusion Cloud HCM bi-directionally and in real time. A person added, moved, or offboarded in Oracle Fusion Cloud HCM creates or updates the matching user in SendGrid within seconds, with field-level mapping and conflict resolution in place of spreadsheets and one-off account changes. Where SendGrid captures details of its own, such as a corrected contact or a login identity, those can flow back to Oracle Fusion Cloud HCM in whichever direction you configure.

Because the sync is field-level, each system keeps its own extras; only the shared facts, who a person is, which team they belong to, and whether their access should be on, are held in agreement.

Common use cases

  • 01 Keep product-usage attributes from an operational database updated on SendGrid contacts to drive lifecycle segments
  • 02 Reconcile transactional email activity with support tickets so agents see what a customer was sent
  • 03 Provision identities and app access downstream when an Atom new-hire or termination feed event fires, joining Workers, Assignments, Departments, and Locations.
  • 04 Replicate Grades and Salaries into a warehouse for compensation and headcount analytics without exporting HDL files.

Common sync patterns

Where SendGrid routes or assigns work by person: assignments follow the org

When someone changes teams or managers in Oracle Fusion Cloud HCM, the queues, ownership, or approvals in SendGrid update to match, so work reaches whoever holds the role now.

Onboarding: access ready on day one

A new hire recorded in Oracle Fusion Cloud HCM creates the matching user in SendGrid with the right team and manager already set, so people can start working without waiting on a provisioning ticket.

Offboarding: no standing access after a departure

When someone is marked as leaving in Oracle Fusion Cloud HCM, the matching account in SendGrid is deactivated or flagged, so departures do not leave open access behind.

What you can sync between Oracle Fusion Cloud HCM and SendGrid

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Oracle Fusion Cloud HCM objects SendGrid objects How this pairing syncs
Departments (Organizations) Org-structure records that define cost centers and reporting lines; typically mastered in HCM and read into other systems. List Synced with incremental and full sync per the Stacksync docs. Departments (Organizations) is specific to Oracle Fusion Cloud HCM and List to SendGrid — each maps to any object or custom field on the other side.
Locations Physical work locations referenced by assignments; synced so downstream provisioning and directory tools resolve the same location codes. Segments Query-based contact groups whose membership SendGrid computes from contact fields. Locations is specific to Oracle Fusion Cloud HCM and Segments to SendGrid — each maps to any object or custom field on the other side.
Grades and Salaries Grade, grade-rate, and worker compensation records; usually read out for compensation and headcount analytics, and written back for corrections. Categories Synced with incremental and full sync per the Stacksync docs. Grades and Salaries is specific to Oracle Fusion Cloud HCM and Categories to SendGrid — each maps to any object or custom field on the other side.
Absences (workerAbsenceEntries) Time-off and leave entries; synced into scheduling or workforce-management databases for coverage planning. Senders Synced with incremental and full sync per the Stacksync docs. Absences (workerAbsenceEntries) is specific to Oracle Fusion Cloud HCM and Senders to SendGrid — each maps to any object or custom field on the other side.
Workers (publicWorkers) Person master with personNumber, names, national IDs, and work relationships; synced two-way via the /workers resource, which replaced the desupported /emps resource. Single Sends One-off marketing campaigns whose stats are read back for reporting. Workers (publicWorkers) is specific to Oracle Fusion Cloud HCM and Single Sends to SendGrid — each maps to any object or custom field on the other side.
Assignments Child of a worker's work relationship carrying job, position, department, location, grade, and manager; effective-dated, so writes go through PATCH with an effective date. Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs. Assignments is specific to Oracle Fusion Cloud HCM and Unsubscribe Groups to SendGrid — each maps to any object or custom field on the other side.

How changes propagate between Oracle Fusion Cloud HCM and SendGrid

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Oracle Fusion Cloud HCM SendGrid Sub-second propagation

DetectionChanges in Oracle Fusion Cloud HCM are captured at the source via change data capture — no polling loop against its API. Atom feeds expose changes-only feeds for key events (new hire, termination, assignment change).

DeliveryEach detected change is written to SendGrid through its API, with automatic retries and rate-limit backoff.

SendGrid Oracle Fusion Cloud HCM Sub-second propagation

DetectionSendGrid notifies Stacksync of record changes through webhook events. Event Webhook posts delivery and engagement events (processed, delivered, open, click, bounce, spam report) to an HTTP endpoint.

DeliveryEach detected change is written to Oracle Fusion Cloud HCM through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Oracle Fusion Cloud HCM: Oracle publishes no fixed per-tenant REST rate limit; pages are capped via limit/offset and Oracle recommends client-side throttling, backoff, and using HDL for mass loads rather than transactional REST.
  • SendGrid: Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes.
