Yes, however you will need to have some semblance of middleware running in a droplet (or other server/machine) that would manage querying the service, consume the result, and store it in the DO Managed DB. The language you choose is your choice.

An example is recently a co-developer and I wrote a script (PHP) that from a droplet queried our CRM service via a webhook that returned a JSON object of the tasks he and I had completed during the week, formats it, and sends the data to our department manager via email. The reason we did this is for a “Bragging” email that is sent to our sales department weekly.
