## Locks
Write endpoints (DELETE, PATCH, POST, PUT methods) can take longer and may
be prone to two concurrent matching requests.
To avoid problems with retrying identical write requests, we have added the
locking function of these requests to the application.
If you execute the same request two times in quick succession, the second
request receives error response with a 423 code.
The lock is only valid for a specific called URL, for the duration of the
request processing, but no longer than 5 seconds.
