@Lup We’ve worked with a number of teams on HubSpot who sync their SQL database in via Hull. Common use cases we’ve seen are to capture product usage data or sync up a data warehouse.
One key challenge with this is calculating the difference on new data and avoiding sending any “silent” updates into HubSpot to prevent burning through API credits. This is hard to do with webhooks or Zapier for a significant volume of data.
We manage this with our SQL Importer which queries for new updates on schedule, and sync only updates with new data to external services.
Here’s a little more how it works:
