The developers built ContactsFlow™ (formerly Shared Contacts for Gmail™) with integrations in mind. The API key is easily accessible so developers can ease up the integration and automation of the shared contacts with third party apps.
Examples of integrations :
Admins can create a ContactsFlow™ (formerly Shared Contacts for Gmail™) API key with a few simple steps.
Note: Only administrator accounts can see the “API Key” menu.
Your API key is now ready to use for accessing your ContactsFlow™ (formerly Shared Contacts for Gmail™) features and data from your business tools.
Keep it secure—anyone with access to this key can view, update, and manage your shared contacts just like an authorized user.
Important Security Note: If the key is ever exposed or is no longer needed, delete it immediately to prevent unauthorized access.
