Hey, @DBionix👋 Thanks for reaching out. My quick search confirms what you are finding, that there is not a 1st or 3rd party app or integration for Checdoc. Nor did I see anything for Zapier or other automations tools. I also did not discover any public developer documents or APIs for their product.
My next step would be to reach out to the Checdoc product team or their support and inquire if they have created an integration or offer APIs you or a developer can use. If not, do they have any documentation on how to connect with external systems such as HubSpot?
