# Create records, as the builder

`POST https://studio.gtable.app/v1/apps/{appId}/tables/{tableId}/records`

Creates one to 500 records in one call, all or nothing: one refused row saves none.

Keys are field ids or exact field names; an unknown key is refused rather than dropped. The whole batch is one changeset, returned as `changesetId`. Email, URL and phone text is preserved; visible suspect values are returned in warnings (code suspect\_format, recordId, fieldId, fieldName, message). A warning is a successful save, not a reason to retry. Invalid numeric values, ratings and ISO dates fail with validation\_failed/422. A failing create batch saves no rows.

Requires the `records:write` scope. Operation `apps.records.create`. MCP tool `apps_records_create`. CLI, once published: `gtable apps records create`.
