Why teams connect Apollo.io and Recurly
Sync customers, invoices, and payment status between Recurly and Apollo.io in real time, so sales sees the money and finance sees the relationship.
Finance and sales describe the same customers in different systems. Apollo.io knows the relationship: who the contacts are and what is in motion with the account. Recurly knows the money: what was invoiced, what was paid, what is overdue. When the two are connected only by exports, each side works partly blind.
Stacksync links Measured Units and Usage, Accounts, Subscriptions, Plans in Recurly to People (database records), Sequences, Deals (Opportunities), Tasks and calls in Apollo.io with bi-directional, real-time sync. New customers, updated billing details, invoice status, and payment activity move in whichever direction you configure, field by field, with conflicts resolved by rules you set. The result is one version of each customer, visible from both sides.
Common use cases
- 01 Trigger revenue-recognition or ERP entries when new_subscription and canceled_subscription webhooks fire.
- 02 Post usage records to Measured Units on metered Subscriptions from a metering database before each bill run.
- 03 Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
- 04 Push CRM opportunity stages back into Apollo so reps see pipeline context while sequencing.
Common sync patterns
Where Apollo.io tracks deals: closed-won creates the finance record
A won opportunity creates or updates the customer in Recurly with the right billing details, so invoicing starts without re-keying.
Payment status on the account
Invoice and payment status from Recurly appears on the account in Apollo.io, so reps see overdue balances before they promise the next order.
Billing detail changes flow back
When a contact or address is corrected in Apollo.io, Recurly gets the update before the next invoice goes out.
What you can sync between Apollo.io 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.
| Apollo.io objects | Recurly objects | How this pairing syncs | |
|---|---|---|---|
| Accounts Company records with firmographic attributes, matched to CRM accounts during sync. | 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. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping. | |
| Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. | Plans The product and pricing catalog (plan codes, intervals, add-ons); usually mastered in Recurly and read out, or mirrored from a product database. | Sequences is specific to Apollo.io and Plans to Recurly — each maps to any object or custom field on the other side. | |
| Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. | Invoices Charge and credit billing documents; read-heavy for revenue reporting, and creatable through Purchases for one-off charges. | Deals (Opportunities) is specific to Apollo.io and Invoices to Recurly — each maps to any object or custom field on the other side. | |
| Tasks and calls Rep activity records synced for activity reporting and coaching workflows. | Transactions Individual payment attempts — captures, refunds, and voids; typically read into a warehouse for reconciliation and dunning analysis. | Tasks and calls is specific to Apollo.io and Transactions to Recurly — each maps to any object or custom field on the other side. | |
| Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. | Line Items One-time charges and credits on an account outside a subscription; synced for accurate revenue and adjustment reporting. | Custom fields is specific to Apollo.io and Line Items to Recurly — each maps to any object or custom field on the other side. | |
| Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. | Coupons and Redemptions Discount definitions and their application to accounts and subscriptions; read for discount and promotion analysis. | Contacts is specific to Apollo.io and Coupons and Redemptions to Recurly — each maps to any object or custom field on the other side. |
How changes propagate between Apollo.io 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.
Apollo.io Recurly Interval-based propagation
DetectionStacksync polls Apollo.io for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at timestamps.
DeliveryEach detected change is written to Recurly through its API, with automatic retries and rate-limit backoff.
Recurly Apollo.io 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 Apollo.io through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Apollo.io: Rate limits and enrichment credits vary by plan; bulk endpoints are throttled separately from single-record calls.
- 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.

FAQ
Apollo.io and Recurly integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Apollo.io and Recurly: authenticate both systems, choose the objects to sync (such as Apollo.io's Accounts and Sequences), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Apollo.io: REST API. Authentication: API key (passed in request headers); master keys unlock account-wide endpoints. Recurly: REST API (V3, date-versioned; legacy V2 XML API also exists). Authentication: API key via HTTP Basic auth (key as username, blank password); keys are per-site, with separate sandbox and production keys. Stacksync manages authentication, retries, and rate limits on both sides.
-
Recurly: V3 authenticates with a per-site API key over HTTP Basic auth (key as username, blank password); sandbox and production sites have separate keys. Apollo.io: Apollo distinguishes between people in its global database and contacts saved to your account; only saved contacts carry your custom fields and sequence history. Stacksync's field mapping accounts for these differences between Apollo.io and Recurly 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 Apollo.io and Recurly records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Apollo.io and Recurly connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Apollo.io–Recurly integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Apollo.io and Recurly. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
