Why teams connect Apollo.io and RingCentral

Keep Apollo.io and RingCentral working from the same contacts, and log every call, message, and meeting back on the record, in real time and in both directions.

Apollo.io holds the people the business talks to: the contacts, their phone numbers and email addresses, and which rep owns the relationship. RingCentral is where the talking happens, whether that is calls, texts, email, or meetings. The two depend on the same people, and when the contact list in one drifts from the other, outreach goes to stale numbers and the record of what was said never makes it back to the account.

Stacksync syncs Tasks and calls, Custom fields, Contacts, Accounts in Apollo.io with Extensions (Users), Contacts (Address Book), RingOut (Click-to-call), Team Messaging (Chat) in RingCentral field by field, in real time, and in both directions. Current contact details flow out to RingCentral so it can reach the right person, and the calls, messages, and meetings RingCentral produces flow back onto the matching record in Apollo.io. You decide which system owns which fields, and conflicts resolve by rules you set.

Common use cases

  • 01 Push CRM opportunity stages back into Apollo so reps see pipeline context while sequencing.
  • 02 Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
  • 03 Send outbound SMS via the /sms endpoint when a CRM or database record changes - appointment reminders, alerts, verification codes - and write inbound replies back onto the record.
  • 04 Load Call Log records (direction, duration, result, recording references) into a warehouse for talk-time, call-volume, and outcome reporting beside pipeline data.

Common sync patterns

One contact list, opt-outs included

A number, address, or unsubscribe recorded in either system updates the other, so no one calls a disconnected line or messages someone who opted out.

New contacts reachable right away

A contact created or updated in Apollo.io appears in RingCentral within seconds, so outreach starts without exporting a list or re-keying numbers.

Where RingCentral reaches out: contacts kept current

Names, phone numbers, email addresses, and the owning rep from Apollo.io stay current in RingCentral, so every call, text, or email goes to the right person at the right address.

What you can sync between Apollo.io and RingCentral

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 RingCentral objects How this pairing syncs
Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. Message Store (SMS / MMS / Fax / Voicemail) Messages in an extension's mailbox - SMS, MMS, fax, voicemail, and pager - read via GET /account/~/extension/~/message-store filtered by dateFrom/dateTo and messageType; outbound SMS is sent via POST /sms, MMS and fax via POST /fax, and messages can be marked read or deleted. Read and write. Custom fields is specific to Apollo.io and Message Store (SMS / MMS / Fax / Voicemail) to RingCentral — 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. Call Log Call detail records with direction, result, duration, from/to numbers, and recording references, from the account-wide and per-extension call-log endpoints, filtered by dateFrom/dateTo. Read-only records. Contacts is specific to Apollo.io and Call Log to RingCentral — each maps to any object or custom field on the other side.
Accounts Company records with firmographic attributes, matched to CRM accounts during sync. Extensions (Users) User extensions with profile, status, roles, and assigned phone numbers via the Configuration API; create, update, and disable extensions to provision or deprovision users and map them to CRM, HR, or directory identities. Read and write. Accounts is specific to Apollo.io and Extensions (Users) to RingCentral — each maps to any object or custom field on the other side.
People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. Contacts (Address Book) Personal address-book contacts per extension with full CRUD via POST/PUT/DELETE /address-book/contact; the company directory has no create endpoint and is read-only, so only personal contacts are writable. Read and write. People (database records) is specific to Apollo.io and Contacts (Address Book) to RingCentral — each maps to any object or custom field on the other side.
Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. RingOut (Click-to-call) Two-legged calls placed programmatically via POST /account/~/extension/~/ring-out, with status polled via GET and calls cancelled via DELETE; a write/action path for click-to-dial from a CRM or internal app. Write. Sequences is specific to Apollo.io and RingOut (Click-to-call) to RingCentral — 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. Team Messaging (Chat) RingCentral team-messaging chats, teams, and posts (formerly Glip); read conversations and create posts, create teams, and add or remove members to mirror org structure. Read and write. Deals (Opportunities) is specific to Apollo.io and Team Messaging (Chat) to RingCentral — each maps to any object or custom field on the other side.

How changes propagate between Apollo.io and RingCentral

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

RingCentral Apollo.io Sub-second propagation

DetectionRingCentral notifies Stacksync of record changes through webhook events. Subscription API webhooks (with a validation-token echo handshake) or WebSocket subscriptions on eventFilters such as message-store/instant,.

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.
  • RingCentral: Per-user (extension) throttling groups per 60 seconds - Heavy 10, Medium 40 (e.g. /sms), Light 50, Auth 5 - as customizable defaults; exceeding returns HTTP 429 with a Retry-After header and X-Rate-Limit-Group/Limit/Remaining/Window headers.
