ClickStack: Create Source

This endpoint is in beta. API contract is stable, and no breaking changes are expected in the future.

ClickStack: Creates a new source. The request body is a source object without the id field. If an id is sent anyway it is silently ignored (stripped before validation — the request is never rejected because of it). Granularity fields (materializedViews[].minGranularity and metadataMaterializedViews.granularity) accept the same short format the API returns (e.g. 5m, 15s, 1h, 1d).

Beta This endpoint is in beta. API contract is stable, and no breaking changes are expected in the future.

ClickStack: Creates a new source. The request body is a source object without the id field. If an id is sent anyway it is silently ignored (stripped before validation — the request is never rejected because of it). Granularity fields (materializedViews[].minGranularity and metadataMaterializedViews.granularity) accept the same short format the API returns (e.g. 5m, 15s, 1h, 1d).
