Create private apps with projects (BETA)
Create private apps to access your HubSpot data through HubSpot's APIs. Private apps can only be installed into the account where they're defined. Using a private app, you can access account data similar to using an API key, but with additional security and usability benefits. You can create multiple private apps per project and per account.
When created as part of a HubSpot project, private apps are stored in a folder that contains an
app.json file, and will also contain extensions and serverless function files needed by the app.
Private apps can include extensions, such as CRM cards, along with serverless functions to power the app and extensions. For example, a private app might include a CRM card to track external ticketing on HubSpot CRM records.
