Why teams connect Smartrecruiters and Supabase

Put your workforce data where your apps can reach it: Supabase and Smartrecruiters share the same people, positions, and org structure in real time.

Smartrecruiters is the system of record for the people side of the business — employees, candidates, roles, and the org structure around them. Supabase is where internal tools, dashboards, provisioning jobs, and analytics actually read and store records. The overlap is the workforce itself: Users, Approvals, Candidates, Applications in Smartrecruiters need to exist as queryable JSONB Columns, Database Functions, Storage Object Metadata, Tables in Supabase before an app can act on them. When that bridge is a nightly export or a hand-run CSV, every downstream system spends the day working from a roster that has already moved on.

Stacksync syncs JSONB Columns, Database Functions, Storage Object Metadata, Tables in Supabase with Users, Approvals, Candidates, Applications in Smartrecruiters field by field, in real time. You decide which system owns which fields — Smartrecruiters typically owns identity and org attributes, while operational or computed values can flow back the other way — and Stacksync keeps every copy consistent, matching records on a stable key and resolving conflicts by rules you set.

The result is one live picture of the workforce on both sides: HR keeps its source of truth, and the database keeps a current mirror that internal apps, reports, and access controls can trust without a batch window in between.

Common use cases

  • 01 Reflect auth.users state into support and CRM systems so teams see account status without querying the database
  • 02 Push product events captured in Supabase Postgres to marketing tools for lifecycle campaigns
  • 03 Write enriched or sourced Candidates from external sourcing tools into SmartRecruiters and keep contact fields refreshed as data changes.
  • 04 Stream Jobs and Job Postings into a reporting database for requisition, funnel, and time-to-fill dashboards.

Common sync patterns

Mirror people records into the database

Records maintained in Smartrecruiters land as queryable JSONB Columns, Database Functions, Storage Object Metadata, Tables in Supabase, so internal apps and dashboards read live data instead of a periodic export.

One directory of record

When a person record is added, changed, or deactivated in either system, the matching row in the other stays current, ending dual maintenance.

Reporting and analytics on current data

Users, Approvals, Candidates, Applications replicate into Supabase where they join operational tables, so headcount, roles, and status reports run on the live state without manual pulls.

What you can sync between Smartrecruiters and Supabase

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.

Smartrecruiters objects Supabase objects How this pairing syncs
Approvals Approval requests for jobs and offers; requests can be created, retrieved as pending, commented on, and approved or rejected via the Approvals API. Storage Object Metadata File metadata rows that can be joined to synced application data. Approvals is specific to Smartrecruiters and Storage Object Metadata to Supabase — each maps to any object or custom field on the other side.
Candidates Person records with contact details, tags, attachments, custom properties, and consent; created, updated, and searched via the Candidates API, often populated from sourcing or enrichment pipelines. Tables Standard Postgres tables; the primary two-way sync target. Candidates is specific to Smartrecruiters and Tables to Supabase — each maps to any object or custom field on the other side.
Applications Links a Candidate to a Job and carries the current hiring status and source; created and advanced through statuses (screening, interview, offer, hired, rejected) via the Application API. Views Read-side projections exposed to outbound syncs. Applications is specific to Smartrecruiters and Views to Supabase — each maps to any object or custom field on the other side.
Jobs Requisitions (positions) with openings, departments, locations, and hiring team; created, patched, and read out for requisition and time-to-fill reporting via the Jobs API. Schemas Namespaces (public and custom) that scope sync access. Jobs is specific to Smartrecruiters and Schemas to Supabase — each maps to any object or custom field on the other side.
Job Postings Job ads and publications pushed to the career site and job boards; created and managed via the job publication endpoints (rate-limited to 2 requests/sec). auth.users Managed authentication users, often mirrored into CRM or support systems. Job Postings is specific to Smartrecruiters and auth.users to Supabase — each maps to any object or custom field on the other side.
Interviews Interview types, timeslots, templates, and scheduled interviews with interviewers and times; created, updated, and read for scheduling and interviewer-load analytics. Row Level Security Policies Row-level access rules that govern what the REST layer exposes. Interviews is specific to Smartrecruiters and Row Level Security Policies to Supabase — each maps to any object or custom field on the other side.

How changes propagate between Smartrecruiters and Supabase

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.

Smartrecruiters Supabase Sub-second propagation

DetectionSmartrecruiters notifies Stacksync of record changes through webhook events. Webhooks API — subscribe to events (new application, candidate updated, status changed) delivered with a signing secret and retrievable callback logs.

DeliveryEach detected change is applied to Supabase as a row-level write, with types converted between the two schemas.

Supabase Smartrecruiters Sub-second propagation

DetectionSupabase pushes changes as they happen — webhook events backed by change data capture. Log-based CDC via Postgres logical replication, the same WAL feed that powers Supabase Realtime.

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

Rate-limit considerations

  • Smartrecruiters: Per API credential: most endpoints allow up to 10 requests/sec (job publication and offer documents 2/sec), plus a concurrency limiter of up to 8 simultaneous requests (GET /candidates capped at 1). Exceeding returns 429; responses carry X-RateLimit-Limit/Remaining and concurrent-limit headers.
  • Supabase: SQL access is bounded by connection limits (pooled connections are provided); the REST layer is subject to the platform's limits.
