Why teams connect Affinity and Aircall
Keep Affinity 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.
Affinity 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 Notes, Interactions, Reminders, Lists in Affinity with Tags, Teams, Messages (SMS/MMS), Webhooks 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 Affinity. You decide which system owns which fields, and conflicts resolve by rules you set.
Common use cases
- 01 Keep introductions and relationship data from Affinity aligned with outreach tools used by the team.
- 02 Sync notes and reminders into project or task systems used outside the deal team.
- 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
Where Aircall reaches out: contacts kept current
Names, phone numbers, email addresses, and the owning rep from Affinity stay current in Aircall, so every call, text, or email goes to the right person at the right address.
Calls, messages, and meetings on the record
Activity handled in Aircall appears on the matching contact and account in Affinity, 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 Affinity, so lead status reflects what actually reached the person.
What you can sync between Affinity and Aircall
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.
| Affinity objects | Aircall objects | How this pairing syncs | |
|---|---|---|---|
| Opportunities Deal records tracked on lists and synced with pipeline reporting. | 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. | Opportunities is specific to Affinity and Calls to Aircall — each maps to any object or custom field on the other side. | |
| Field Values Custom field data, either global or scoped to a list, mapped field-by-field in 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. | Field Values is specific to Affinity and Users to Aircall — each maps to any object or custom field on the other side. | |
| Notes Meeting and call notes synced for record-keeping in other systems. | Numbers Provisioned phone numbers with settings, open hours, and IVR config; read and update to keep routing and business-hours data aligned across systems. | Notes is specific to Affinity and Numbers to Aircall — each maps to any object or custom field on the other side. | |
| Interactions Automatically captured emails and meetings, read for activity reporting. | Tags Call tags with name and color; full CRUD, applied to calls for disposition and outcome reporting in the CRM or warehouse. | Interactions is specific to Affinity and Tags to Aircall — each maps to any object or custom field on the other side. | |
| Reminders Follow-up tasks associated with people and organizations. | 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. | Reminders is specific to Affinity and Teams to Aircall — each maps to any object or custom field on the other side. | |
| Lists Pipelines (deal flow, fundraising, portfolio) that structure most Affinity data; syncs usually target a specific list. | 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. | Lists is specific to Affinity and Messages (SMS/MMS) to Aircall — each maps to any object or custom field on the other side. |
