Information noteCalls to the QRS API must include Xrfkey headers. See Using Xrfkey headers for information on how to apply the headers.
Tip noteMany JSON structs in the Qlik Sense Repository Service (QRS) API include the modifiedDate property, which is used to avoid conflicts in the repository database. For example, when updating an entity, leave the modifiedDate property unchanged. If the modifiedDate property for the updated entity differs from the modifiedDate property for the entity in the QRS, there is a conflict (that is, the entity in the QRS has already been updated by someone else).
