Auth

OAuth and tokens

The app uses HubSpot OAuth, exchanges tokens through HubSpot's date-based OAuth v3 token endpoint, stores refresh tokens encrypted at rest, and does not expose tokens in docs or dashboard UI.
Request integrity

Signed app-card requests

App-card requests are sent by HubSpot to Company Data Guys. The backend validates HubSpot request signatures before processing enrichment requests.
Operations

Reliability

When a company profile cannot be resolved from the available fields, the app reports the problem in the card instead of writing unrelated data. The app records the last successful card activity timestamp for support and audit.
Privacy

No model training

Customer HubSpot data is used only to provide the integration. It is not used to train or improve shared AI or machine-learning models.
