Option to not execute a REST query

[dgooris]

Would it be an idea to have an option to not send any REST query, so that it only does a mysql query.
A possible Use Case would be to press a button that only updates a mysql table entry. A process that monitors changes of this mysql table could trigger further actions.

Implementation of such an option may be possible to simply leave the URL of REST Integration empty:
If the url is not defined, it simply does not invoke any REST query.

Currently, when leaving the url empty, the button shows a rotating icon as if something is running but most likely is not.

Thanks in advance and kind regards.
