# Replace project data source

`PUT` `/api/v1/carve/projects/{project_id}/data-sources/{data_source_id}`

Replace an existing attached data source with a new one of the same type.
The replacement inherits the primary/non-primary status of the data source
it replaces.

Set `use_credits` to true to allow the replacement to exceed the row limit
by charging credits for the overage (1 credit per 10 rows above the limit)
when replacing a primary data source. Returns 422 if the account has
insufficient credits.

The account sheet will need to be refreshed to reflect any changes.
