Why teams connect Aircall and Nutshell
Keep Nutshell 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.
Nutshell 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, Products, Tags, Users in Nutshell with Webhooks, Contacts, Calls, Users 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 Nutshell. You decide which system owns which fields, and conflicts resolve by rules you set.
Common use cases
- 01 Keep People and Companies consistent between Nutshell and email marketing or outreach tools.
- 02 Write subscription or product data from internal systems into Nutshell so reps see account context.
- 03 Send outbound SMS/MMS through the Messages API when a CRM or database record changes (appointment reminders, alerts) and write inbound replies back.
- 04 Sync Tags and call dispositions onto matching CRM records as call outcomes so RevOps can report on conversation activity.
Common sync patterns
Calls, messages, and meetings on the record
Activity handled in Aircall appears on the matching contact and account in Nutshell, 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 Nutshell, 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 Nutshell
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 | Nutshell 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 Rep records used to resolve ownership when syncing assignments | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Tags Call tags with name and color; full CRUD, applied to calls for disposition and outcome reporting in the CRM or warehouse. | Tags Segmentation labels mapped to lists or filters in downstream tools | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Webhooks Event subscriptions for call, contact, user, message, and number events; full CRUD, the mechanism for near-real-time change delivery to Stacksync. | Activities Logged calls, meetings, and emails used for engagement reporting | Webhooks is specific to Aircall and Activities to Nutshell — each maps to any object or custom field on the other side. | |
| 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. | Tasks Rep to-dos mirrored into external work-management or reporting systems | Contacts is specific to Aircall and Tasks to Nutshell — each maps to any object or custom field on the other side. | |
| 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. | Notes Free-text history attached to leads and contacts, replicated for a full timeline | Calls is specific to Aircall and Notes to Nutshell — 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. | Products Line items attached to leads, used to sync sold products into billing | Numbers is specific to Aircall and Products to Nutshell — each maps to any object or custom field on the other side. |
How changes propagate between Aircall and Nutshell
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 Nutshell 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 Nutshell through its API, with automatic retries and rate-limit backoff.

FAQ
Aircall and Nutshell integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Aircall and Nutshell: authenticate both systems, choose the objects to sync (such as Aircall's Users and Tags), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Nutshell: The deal object is called a Lead in Nutshell, and it links to separate People and Company records rather than replacing them. Aircall: Calls are read-oriented: the call record cannot be created or edited, but you can add tags, comments, and insight cards, transfer, archive, and control recording; genuine writes live in Contacts, Users, Tags, Teams, and Messages. Stacksync's field mapping accounts for these differences between Aircall and Nutshell without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Aircall and Nutshell records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Aircall and Nutshell connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Aircall–Nutshell integration in-house.

On Nutshell: Webhook subscriptions for record events, with polling as fallback. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
