It looks like Operations Hub Data Sync is available only for a predefined set of third party applications through connectors that HubSpot has created. I would like to integrate my company’s proprietary app as well. Is there documentation that I could use to build my own connector so it will be compatible with Operations Hub Data Sync?
Hey, @danhammari 
Thanks for your question. There is not a set of endpoints or specific documentation for this type of connection. As you mentioned, the available connectors are pre-defined.
To help our community better understand your project, I have a few questions:
- What’s the functionality you’re seeking?
- Are you looking for a two-way sync or just a one-way data push into HubSpot?
- What type of data are you trying to sync (e.g., contacts, companies, deals, tickets)?
- Do you need a one-way or two-way sync?
Knowing details like this helps the community to understand your project.
Thank you! — Jaycee
