Kustomer to Microsoft Dynamics 365 Sales integration — real-time, two-way sync

Yes. Stacksync provides a managed, real-time two-way integration between Kustomer and Microsoft Dynamics 365 Sales: authenticate both systems, choose the objects to sync (such as Kustomer's Notes and Customers), map fields visually, and changes propagate both ways in milliseconds — no code required.

On the Kustomer side: Customers, Conversations, Messages, Companies, plus custom fields where Kustomer exposes them. On the Microsoft Dynamics 365 Sales side: Activities, Custom Tables, Accounts, Contacts. Stacksync auto-detects both schemas and converts types between the two systems.

Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.

Common patterns for Kustomer and Microsoft Dynamics 365 Sales: Where both track pipeline: deal visibility across systems; Post-acquisition consolidation; Migration with a parallel run. Deal stage and value on shared accounts stay visible from either CRM.

Kustomer: REST API. Authentication: API key used as a bearer token, scoped by role. Microsoft Dynamics 365 Sales: Dataverse Web API (OData v4 REST). Authentication: OAuth 2.0 via Microsoft Entra ID. Stacksync manages authentication, retries, and rate limits on both sides.

Kustomer: Custom object types are called Klasses, and they are the standard mechanism for landing external data like orders and subscriptions where agents work. Microsoft Dynamics 365 Sales: Data lives in Dataverse tables exposed through an OData v4 Web API, so standard query options handle filtering, expansion, and paging. Stacksync's field mapping accounts for these differences between Kustomer and Microsoft Dynamics 365 Sales without custom code.
