Bulk Update Limitations for Segment Profiles Sync's Selective Sync API – Twilio Support

Issue

When using the Segment Public API Update Selective Sync for Warehouse and Space endpoint to configure which properties sync to a profiles warehouse, we encounter a 10-item limit per request. This becomes a challenge when managing hundreds of property-level overrides as configuration grows, especially in Infrastructure as Code (IaC) workflows.

Environment

Cause

The 10-item limit per PATCH request is a design constraint of the Segment Public API. There is no bulk endpoint or configurable option to increase this limit.

Resolution

To update more than 10 items, send multiple PATCH requests, each with up to 10 items.
For large-scale configuration management, consider:
- Modifying automation to calculate and send only the changes (deltas) rather than the full configuration.
- Decoupling the update process from CI/CD pipelines by triggering an asynchronous function (such as AWS Lambda) to handle batching and rate limits outside of the main deployment workflow.
