Problem Definition

The current API Endpoints only allow updating 1 Field at a time:

• API Group Customer - PUT Update the value of a detail field for a given organization

Suggested Solution

Provide an Endpoint that can update multiple values at once, or alter this Endpoint to do so.
There is a CSV Import to bulk update Details, but it has bugs like empty spaces causing errors even when it still imports the rest of the information:

• Improve customers and organizations CSV import result error messages - JSDCLOUD-13515
• Cannot set a CSM detail field value to empty when using CSV import - JSDCLOUD-13520

Workaround

Either produce a script that will repeatedly access the Update Endpoint to update Values 1 by 1, or use the CSV Import after removing any problematic columns or rows that would result in an error.
