Why teams connect Apollo.io and Zuora

Sync customers, invoices, and payment status between Zuora 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. Zuora 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 Order and Amendment, Account (Billing Account), Subscription, Rate Plan and Rate Plan Charge in Zuora to Sequences, Deals (Opportunities), Tasks and calls, Custom fields 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 Two-way sync of Accounts and Subscriptions with an operational Postgres database so product and finance teams read billing state in SQL while changes flow back into Zuora.
  • 02 Master the Product Catalog (Products and Product Rate Plans) in a database or PIM and write pricing changes into Zuora.
  • 03 Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
  • 04 Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.

Common sync patterns

Where Apollo.io tracks deals: closed-won creates the finance record

A won opportunity creates or updates the customer in Zuora with the right billing details, so invoicing starts without re-keying.

Payment status on the account

Invoice and payment status from Zuora 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, Zuora gets the update before the next invoice goes out.

How changes propagate between Apollo.io and Zuora

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

Zuora Apollo.io Sub-second propagation

DetectionZuora notifies Stacksync of record changes through webhook events. Incremental extraction on the indexed UpdatedDate column via ZOQL/AQuA stateful mode (high-water mark), plus Callout Notifications (webhooks) for.

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.
  • Zuora: Concurrency limits: 40 concurrent requests by default, 80 for Object Queries, 200 for high-volume operations (doubled for Performance Booster); HTTP 429 on breach with exponential backoff; OAuth token endpoint is not bound by the limit.
