ZoomInfo

Integrate ZoomInfo with Delos to enrich your B2B data and access contact and company information.

Prerequisites

  • ZoomInfo GTM.ai or Enterprise license with API access
  • ZoomInfo admin rights
  • Delos account with integration rights

⚠️ ZoomInfo’s MCP OAuth access is still being rolled out on the partner side; some settings (client ID, secret, scopes) will be finalized once access is validated.

Steps

  1. Create an app in the ZoomInfo Developer Portal (or GTM.ai Developer tab).
  2. Choose Client Credentials or Authorization Code + PKCE, configure the redirect URL and minimal API scopes.
  3. Retrieve the Client ID and Client Secret.
  4. In Delos, open Connectors > ZoomInfo, enter credentials and validate the connection.
  5. Each authorized user then completes the OAuth connection.

Troubleshooting

  • invalid_client: recheck Client ID/Secret.
  • 429: rate limit reached, space out requests.

Revocation

Disconnect the connector in Delos and delete/revoke the app on ZoomInfo side.

⚠️ ZoomInfo prohibits using MCP-accessed data to train AI models.
