The `destinationId` of a sync template cannot be changed after creation. Syncs created from the template pick up a new `configuration` on their next run; a new `overrideConfig` replaces the previous one and applies to the next write of each sync's `syncTemplateOverrides`. ## OpenAPI ````yaml https://api.hightouch.io/api/swagger.json patch /sync-templates/{syncTemplateId} openapi: 3.0.0 info: title: Hightouch API version: 1.0.0 description: Hightouch Public Rest API to access syncs, models, sources and destinations contact: name: Hightouch url: https://hightouch.com servers: - url: https://api.hightouch.com/api/v1 security: [] paths: /sync-templates/{syncTemplateId}: patch: summary: Update Sync Template description: >- Update an existing sync template Patch a sync template based on its Hightouch ID.
