Concurrency handling

We have concurrency controls in place for PUT and DELETE actions.

You must first obtain a concurrency token or RowVersion property before you can update or delete a resource.

• Obtain the concurrency token or RowVersion property via the GET action for the resource you want to update or delete
• Insert the concurrency token or RowVersion property in If-Match HTTP Request Header when executing the PUT or DELETE action

The PUT and DELETE actions will be successfully processed only if the resource concurrency token value has not changed. If the resource state has changed,401 – Unauthorized, will be returned.
