# Update a record, as the builder

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

A partial update: only the fields sent are changed.

The body is \{"fields":\{…}}, keyed by field id or exact name. Logged as this builder, from the Studio. 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.update`. MCP tool `apps_records_update`. CLI, once published: `gtable apps records update`.
