Hi,
Is it possible to build your own api endpoint in HubSpot that can be called from an external application?
Thank you in advance for this information.
What are you trying to achieve?
There is a pretty extensive API in place that you can utilize to interact with your hubspot data.
is a starting place and that also has links to SDK’s for making calls easier. When you are looking through the endpoints on those pages, it is interactive, so you can set pramaters and it will update the example code for each sdk language.
