Why teams connect Demandbase and Supabase

Give your team Demandbase's contacts, campaigns, and engagement in Supabase: query them with SQL, push audiences built from your own data back to Demandbase, and skip the marketing API.

Demandbase holds the people, audiences, and campaign activity that marketing runs on, but that data sits behind interfaces built for marketers, not for your internal systems. Engineers and analysts who need contacts, list membership, or engagement, for reporting, attribution, or product logic, end up writing integration code against a rate-limited API and maintaining it forever. Meanwhile the customer and usage data marketers want for targeting already lives in Supabase, hard to get into campaigns without manual exports.

Stacksync mirrors Account & Person Lists (Audiences), Company Details (B2B enrichment), Change Subscriptions, Accounts from Demandbase into Schemas, auth.users, Row Level Security Policies, JSONB Columns in Supabase field by field, in real time, and in both directions. Marketing records become rows your code can query and join with product and customer data; audiences and attributes computed in Supabase, from usage, orders, or account status, sync back into Demandbase to drive campaigns and ads, with Demandbase kept authoritative for engagement. You decide which side owns which fields, and Stacksync resolves conflicts by rules you set.

Common use cases

  • 01 Push product events captured in Supabase Postgres to marketing tools for lifecycle campaigns
  • 02 Consolidate Supabase project data into a warehouse for analytics while keeping the app database as the system of record
  • 03 Sync Opportunities and Activities two-way so CRM deal and engagement data flows into Demandbase reporting and Demandbase-calculated insights flow back to the warehouse.
  • 04 Subscribe to Demandbase company and person change webhooks - firmographic updates, M&A, and leadership or employment changes - and land them in an operational store for real-time account alerts.

Common sync patterns

Build audiences from your own data

Segments computed in Supabase from product usage, orders, or account status sync into Demandbase as lists or audiences, so campaigns and ads target the people your data says they should.

Engagement and results next to the customer

Opens, clicks, sends, RSVPs, or ad activity from Demandbase land in Supabase beside the matching customer record, ready for reporting and revenue attribution.

React to marketing changes as row changes

A new lead, form fill, or list change in Demandbase arrives as a row change in Supabase, so scoring, jobs, and notifications run in the tooling your team already uses.

What you can sync between Demandbase 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.

Demandbase objects Supabase objects How this pairing syncs
Account & Person Lists (Audiences) Named account and person segments exported via Data Export; custom audiences pushed into Demandbase through the Data Import API. Read and write. Schemas Namespaces (public and custom) that scope sync access. Account & Person Lists (Audiences) is specific to Demandbase and Schemas to Supabase — each maps to any object or custom field on the other side.
Company Details (B2B enrichment) Firmographics, technographics, competitors, and corporate family tree fetched by domain or name via the B2B Company Search and Details endpoints; read-only enrichment. auth.users Managed authentication users, often mirrored into CRM or support systems. Company Details (B2B enrichment) is specific to Demandbase and auth.users to Supabase — each maps to any object or custom field on the other side.
Change Subscriptions Company firmographic, company news, family-tree (ownership), and DB person employment subscriptions delivered as webhook alerts with a signing secret; the real-time change feed. Row Level Security Policies Row-level access rules that govern what the REST layer exposes. Change Subscriptions is specific to Demandbase and Row Level Security Policies to Supabase — each maps to any object or custom field on the other side.
Accounts Company/account records with firmographics, intent, and Demandbase qualification and engagement scores; exported via the Data Export API and imported or updated via the Data Import API. JSONB Columns Semi-structured payloads such as event properties or nested objects. Accounts is specific to Demandbase and JSONB Columns to Supabase — each maps to any object or custom field on the other side.
Opportunities Opportunity records synced from the CRM into Demandbase; exported with calculated insights and imported or updated through the Data Import API. Read and write. Database Functions Postgres functions that can transform or validate synced rows. Opportunities is specific to Demandbase and Database Functions to Supabase — each maps to any object or custom field on the other side.
People (Persons) Contact/person records with verified business email, title, seniority, and quality grades; fetched and matched via the B2B Contact endpoints and exported or imported. Storage Object Metadata File metadata rows that can be joined to synced application data. People (Persons) is specific to Demandbase and Storage Object Metadata to Supabase — each maps to any object or custom field on the other side.

How changes propagate between Demandbase 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.

Demandbase Supabase Sub-second propagation

DetectionDemandbase notifies Stacksync of record changes through webhook events. Subscription API webhooks - company firmographic, company news, family-tree (ownership), and person employment-change alerts to a configurable URL.

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

Supabase Demandbase 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 Demandbase through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Demandbase: Credit-based per API call; bulk jobs accept up to 10,000 records per submission, CSV uploads up to 5GB, and result URLs stay valid 24 hours; subscription alerts page up to 5,000 entities and list endpoints up to 100 per page.
  • Supabase: SQL access is bounded by connection limits (pooled connections are provided); the REST layer is subject to the platform's limits.

How the Demandbase and Supabase connectors work

Demandbase

Integration surface
REST APIs (Demandbase One) - a B2B API (company/contact search, details, and match with async bulk enrichment jobs), a read-only Data Export API and a write-capable Data Import API (both async bulk jobs), and a Subscription API for webhook change alerts.
Authentication
JWT bearer tokens minted from Demandbase One API Key Sets at the platform level; each credential set expires after 8 hours and is rotated. Legacy single-user API tokens are deprecated.
Change detection
Subscription API webhooks - company firmographic, company news, family-tree (ownership), and person employment-change alerts to a configurable URL secured with a signing secret; bulk reads run as async export jobs (submit, poll, download). No log-based CDC.
