# Insert Bulk Customers

`POST /loaddata/C`

Inserts multiple customers to the Master Data table.<p>
The **/loaddata** operation is a very efficient and quick way to insert bulk data to the Master Data table.
The main advantage is its greater speed when loading thousands of records (compared to e.g. **/integrate**).<p>
<!-- theme: warning -->
>**Please note**
> If no `joinFields` are provided in the request, then this operation will insert entire records. It means that in this case (without `joinFields`) with **/loaddata** it is not possible to update just some fields (for this use the **/integrate** endpoint instead). The source data must always contain the entire row’s content.
