Why teams connect Firebase and Recurly

Work with Recurly's financial data straight from Firebase: read it with ordinary queries, write to it from your own code, and let Stacksync keep both sides consistent.

Engineers need finance data more often than finance systems make it easy to get: for internal tools, reporting services, or logic that reacts to invoices and payments. Working through the vendor API means rate limits, pagination, and glue code that has to be maintained forever.

Stacksync mirrors Subscriptions, Plans, Invoices, Transactions from Recurly into Authentication Users, Cloud Storage Objects, Cloud Functions Triggers, Firestore Collections in Firebase and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Firebase, and rows your code writes or updates flow back into Recurly with validation, so the finance system stays the system of record.

Common use cases

  • 01 Sync Accounts and Subscriptions bi-directionally with Postgres so product and provisioning systems read live entitlement state and write plan or seat changes back to Recurly.
  • 02 Trigger revenue-recognition or ERP entries when new_subscription and canceled_subscription webhooks fire.
  • 03 Combine Firebase Authentication users with billing and CRM records into one customer table.
  • 04 Replace one-off Cloud Functions export code with managed, continuous sync.

Common sync patterns

React to financial events

Changes in Recurly appear in Firebase as row changes, so you can trigger downstream logic with the database tooling you already use.

Query finance data like any other data

Customers, invoices, and payments from Recurly live in Firebase as regular tables or collections your team can join, index, and query.

Internal tools without API plumbing

Build dashboards and back-office tools directly on Firebase; Stacksync handles the API calls, rate limits, and retries against Recurly.

What you can sync between Firebase and Recurly

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.

Firebase objects Recurly objects How this pairing syncs
Subcollections Nested collections under documents, typically flattened into related tables during sync. Billing Info Tokenized payment method (card/ACH) on an account; written when onboarding customers and read for payment-health signals (never stores raw card numbers). Subcollections is specific to Firebase and Billing Info to Recurly — each maps to any object or custom field on the other side.
Realtime Database Nodes JSON tree paths in the older Realtime Database, synced by path. Measured Units and Usage Metered-billing units; usage records are posted to a subscription before each bill run for consumption-based pricing. Realtime Database Nodes is specific to Firebase and Measured Units and Usage to Recurly — each maps to any object or custom field on the other side.
Authentication Users User accounts read into CRMs and warehouses for customer records. Accounts Customer/billing entity records keyed by account_code; the anchor most subscriptions and invoices hang off. Synced two-way with CRM accounts or a customer database. Authentication Users is specific to Firebase and Accounts to Recurly — each maps to any object or custom field on the other side.
Cloud Storage Objects Files referenced from documents; usually synced as metadata plus URLs. Subscriptions Recurring subscription records tied to an Account and a Plan, with state, term, and next-bill date. Core object, synced two-way to drive provisioning and reporting. Cloud Storage Objects is specific to Firebase and Subscriptions to Recurly — each maps to any object or custom field on the other side.
Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. Plans The product and pricing catalog (plan codes, intervals, add-ons); usually mastered in Recurly and read out, or mirrored from a product database. Cloud Functions Triggers is specific to Firebase and Plans to Recurly — each maps to any object or custom field on the other side.
Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects. Invoices Charge and credit billing documents; read-heavy for revenue reporting, and creatable through Purchases for one-off charges. Firestore Collections is specific to Firebase and Invoices to Recurly — each maps to any object or custom field on the other side.

How changes propagate between Firebase and Recurly

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.

Firebase Recurly Interval-based propagation

DetectionStacksync polls Firebase for changes on an incremental schedule, reading only records changed since the previous pass. Real-time snapshot listeners on Firestore queries and Cloud Functions triggers on document changes.

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

Recurly Firebase Sub-second propagation

DetectionRecurly notifies Stacksync of record changes through webhook events. Webhooks (JSON or XML, one format per endpoint) for account, subscription, payment, and invoice events, plus incremental polling of list endpoints.

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

Rate-limit considerations

  • Firebase: Subject to Firestore's documented operation quotas and per-document write throughput limits.
  • Recurly: Production sites default to 1,000 requests/min with only GET requests counting toward the limit; sandbox sites 400/min with all requests counting; the limit is a sliding 5-minute window, X-RateLimit headers report the quota, and breaches return HTTP 429.
