JSON Master Data Upload File
This file contains the data that must be processed according to the JSON Master Data template.
The JSON Master Data template file must either be uploaded in the Data Hub account's storage prior to the upload of the data file or be included in the data file under the template element. The template element can be the JSON Master Data template itself or the name of a JSON Master Data template to lookup in the Data Hub's Storage
There is no other constraint on this file other than having at least a valid empty object:
{
}
This also means that:
- any JSON path specified in the template is optional in the Master Data Upload File
- any element in Master Data Upload file that does not exit in the Master Data Template file is ignored
