This is a longstanding need. As a use case we have an automation that processes documents for multiple states. We have the state, along with other info, in the Reference of the queue items. We would like to be able to control which stateS it processes, using a Reference filter. For example, we may want it to pick up queue items for FL and AL and LA, but then on a moment’s notice (config file) may need to turn off a particular state.
So the basic answer is YES, good old OData filters are an important need. Doesn’t seem like a difficult thing for you to add to an upcoming version of the activity. This is for Get Transaction but would also probably be useful to many in Get Queue Items. Get Queue Items also shouldn’t have a limit of 100. That makes retrieving more queue items painful.
