Hey there - @Jaycee_Lewis is right, if you need to access it via API. You’ll have to use one of the numerous serverless services in order to do so. I’ve used Cyclic in the past, when I wanted to get something up and running quickly. Easy to set up, performance is up to par, cost effective.
There’s also AWS Lambda, Azure, Google App Engine, Heroku - there are lots of em.
However - HubSpot’s modules have hubdb fields. Depending on the specifics at play here, you could use those fields to make the query in your module.html file, perhaps with the help of one of the hubl hubdb functions and pass the data to your Component files as parameters. You could then do whatever you need to do with it there. If you can’t just retrieve the data in bulk, or if the table that needs to be queried is going to differ based on some kind of user action on the front end…this avenue may not be the way.
