# Upload a Bulk Data to Data Source

Uploads a chunk (batch) of data from a client resource to the storage reserved for a particular Data Source.
The uploaded data is not immediately transfered to the Data Source database table. Instead it is held (‘buffered’) in a staging area, until an explicit flush command is issued (refer to the /datamart.rundataload endpoint, "type": "DS_FLUSH"), or a Datamart dependent on the Data Source data is refreshed.

Endpoint: POST /datamart.loaddata/{datasourceUniqueName}
