# Custom Synapse (SDK)

Syncari's Custom Synapse SDK lets you connect proprietary or niche systems directly to your unified entity model, applying the same deduplication, validation, and activation capabilities available to every native Synapse. Build once and let Syncari handle schema changes and cross-system consistency automatically.

### Market leaders connected with Syncari

### How it works

The Syncari SDK enables our partners and customers to build Custom Synapses and expand their data ecosystem beyond the pre-built Synapse library. The SDK is built using Python, with certification, hosting and management of Synapse provided by Syncari.

With the SDK it is possible to connect to any system that exposes an API (SOAP, REST, GraphQL or webhook) endpoint by building Synapses that are equal to their native counterparts. For use cases that don’t require a unified data model, we provide [Custom Actions](/content/blog/introducing-custom-actions/index.html), which can be used to trigger data in a 3rd party system or to fetch data in the context of pipelines.

More information on both Custom Synapses and Custom Actions is available in the video below:
