Insert Bulk Customer Extensions

Inserts multiple customers extensions to the Master Data table.<p> The name (a name of the category) and customerId must be provided for each record in the header and data object within the request body.

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.
