Updating the credentials for a datasource is generally done using these sorts of JSON passed to UpdateDatasourceAsync...
{
"credentials":"{\"credentialData\":[{\"name\":\"key\",\"value\":\"hi...rg==\"}]}",
"credentialType": "Key",
"encryptedConnection": "Encrypted | NotEncrypted", // chose one
"privacyLevel": "None | Private | Organizational | Public", // chose one
"encryptionAlgorithm":"None"
}
* Is this documented anywhere? e.g. what should the format for 'credentials' be for other types of datasources? I feel that we shouldn't have to come to this forum for this sort of information.
* Rather than crafting a JSON string, it would be good if the PowerBI Client SDK supported a strongly-typed class for each datasource type.
* EncryptedConnection/PrivacyLevel/EncryptedAlgorithm: is there any documentation around these at all? When should they be used? What types of datasource do they apply to?
* Datasource Name: The datasource object that is returned by various APIs has a 'DatasourceName' property - this is invariably blank. It would be handy to have this populated in the event that a report had multiple datasources of the same type - it is possible to distinguish between them via the ConnectionDetails property, however that is a bit tricky. I'm assuming that this relies on Power BI Desktop supporting datasource names that it currently doesn't.
