Why teams connect Aircall and Apollo.io

Keep Apollo.io and Aircall 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. Aircall 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 Accounts, People (database records), Sequences, Deals (Opportunities) in Apollo.io with Users, Numbers, Tags, Teams in Aircall field by field, in real time, and in both directions. Current contact details flow out to Aircall so it can reach the right person, and the calls, messages, and meetings Aircall 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 Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
  • 02 Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
  • 03 Provision and deprovision Users and Team membership from an HR system or IdP so the agent roster, seats, and routing groups stay current.
  • 04 Send outbound SMS/MMS through the Messages API when a CRM or database record changes (appointment reminders, alerts) and write inbound replies back.

Common sync patterns

Calls, messages, and meetings on the record

Activity handled in Aircall appears on the matching contact and account in Apollo.io, so the next person sees the full history without leaving the CRM.

Where Aircall sends at scale: delivery and reply status back on the contact

Sends, bounces, opens, and replies from Aircall update fields on the contact in Apollo.io, so lead status reflects what actually reached the person.

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.

What you can sync between Aircall and Apollo.io

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.

Aircall objects Apollo.io objects How this pairing syncs
Contacts Shared and personal phone-book contacts with full CRUD plus search by phone number or email; the primary two-way object synced with CRM contacts for click-to-dial. Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Calls Inbound and outbound call records with recording URL, duration, tags, comments, and metadata; the record itself is read-only, but you can add tags, comments, insight cards, transfer, archive, and control recording. Tasks and calls Rep activity records synced for activity reporting and coaching workflows. Calls is specific to Aircall and Tasks and calls to Apollo.io — each maps to any object or custom field on the other side.
Users Agent seats with name, email, and availability; full CRUD to provision or deprovision seats and map Aircall agents to CRM, HR, or directory identities. Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. Users is specific to Aircall and Custom fields to Apollo.io — each maps to any object or custom field on the other side.
Numbers Provisioned phone numbers with settings, open hours, and IVR config; read and update to keep routing and business-hours data aligned across systems. Accounts Company records with firmographic attributes, matched to CRM accounts during sync. Numbers is specific to Aircall and Accounts to Apollo.io — each maps to any object or custom field on the other side.
Tags Call tags with name and color; full CRUD, applied to calls for disposition and outcome reporting in the CRM or warehouse. People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. Tags is specific to Aircall and People (database records) to Apollo.io — each maps to any object or custom field on the other side.
Teams Groups of users for routing and reporting; create and delete teams and add or remove members to mirror org structure from an HR system or IdP. Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. Teams is specific to Aircall and Sequences to Apollo.io — each maps to any object or custom field on the other side.

How changes propagate between Aircall and Apollo.io

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.

Aircall Apollo.io Sub-second propagation

DetectionAircall notifies Stacksync of record changes through webhook events. Webhooks (POST /v1/webhooks) for call, contact, user, message, and number events.

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

Apollo.io Aircall 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 Aircall through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Aircall: 60 requests per minute per company by default (120/min for Advanced Messaging customers); responses carry X-AircallApi-Limit, X-AircallApi-Remaining, and X-AircallApi-Reset headers.
  • Apollo.io: Rate limits and enrichment credits vary by plan; bulk endpoints are throttled separately from single-record calls.
