Two-way sync
Changes in Aircall or Attio instantly reflect in both systems. No stale data, no manual imports.
Keep Aircall and Attio in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
Attio 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 Deals, Workspaces, Custom objects, People in Attio with Calls, Users, Numbers, Tags 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 Attio. You decide which system owns which fields, and conflicts resolve by rules you set.
Sends, bounces, opens, and replies from Aircall update fields on the contact in Attio, so lead status reflects what actually reached the person.
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.
A contact created or updated in Attio appears in Aircall within seconds, so outreach starts without exporting a list or re-keying numbers.
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 | Attio objects | How this pairing syncs | |
|---|---|---|---|
| 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. | Users Synced with incremental and full sync per the Stacksync docs. | 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. | Workspaces Synced with incremental and full sync per the Stacksync docs. | Calls is specific to Aircall and Workspaces to Attio — 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. | Custom objects Workspace-defined objects that behave like standard ones in the API. | Numbers is specific to Aircall and Custom objects to Attio — 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 Standard person object; synced with marketing tools and warehouse person tables. | Tags is specific to Aircall and People to Attio — 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. | Companies Standard company object; matched to billing and product accounts in two-way syncs. | Teams is specific to Aircall and Companies to Attio — each maps to any object or custom field on the other side. | |
| Messages (SMS/MMS) Text messages tied to a number and contact; send outbound SMS/MMS through the API and read inbound messages delivered via webhook events. | Deals Pipeline records; read out for revenue reporting and written to from automation. | Messages (SMS/MMS) is specific to Aircall and Deals to Attio — each maps to any object or custom field on the other side. |
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.
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 Attio through its API, with automatic retries and rate-limit backoff.
DetectionAttio notifies Stacksync of record changes through webhook events. Webhooks on record and list-entry events, with polling as a fallback.
DeliveryEach detected change is written to Aircall through its API, with automatic retries and rate-limit backoff.

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate Aircall and Attio with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Aircall and Attio objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Aircall and Attio: authenticate both systems, choose the objects to sync (such as Aircall's Users and Calls), map fields visually, and changes propagate both ways in milliseconds — no code required.
Common patterns for Aircall and Attio: Where Aircall sends at scale: delivery and reply status back on the contact; One contact list, opt-outs included; New contacts reachable right away. Sends, bounces, opens, and replies from Aircall update fields on the contact in Attio, so lead status reflects what actually reached the person.
Aircall: REST API (Aircall Public API v1, https://api.aircall.io/v1). Authentication: HTTP Basic auth (base64 api_id:api_token) for single-account integrations, or OAuth 2.0 authorization_code flow for multi-tenant Technology Partner apps. Attio: REST API. Authentication: Guided in-app connection ("Attio CRM" connection created in a few clicks, "without any coding required"); the docs do not name the underlying auth mechanism (OAuth vs API key). Stacksync manages authentication, retries, and rate limits on both sides.
Attio: Records are distinct from list entries; the same company can appear in multiple lists with list-specific attribute values, which a faithful sync replicates separately. Aircall: Contacts support full CRUD plus search by phone number or email, making them the primary two-way object for keeping Aircall and a CRM in sync. Stacksync's field mapping accounts for these differences between Aircall and Attio without custom code.
