Your organization must have an Enterprise API or Copilot package, and a ZoomInfo admin must assign you the DevPortal subscription via Admin Portal > User Management > Users before you can sign in to the Developer Portal.

​
Register an app in the ZoomInfo Developer Portal

Apps are created in the ZoomInfo Developer Portal (DevPortal). You’ll need admin access to your ZoomInfo account.

1

Sign in to the ZoomInfo Developer Portal

Sign in to your ZoomInfo Developer Portal account.

  • Navigate to Apps.
2

Create a new app

Click Create App and configure it for the Authorization Code (PKCE) grant.

  • Enter a meaningful application name (for example StackOne Integration).
  • Under Sign-in redirect URIs (DevPortal uses the Okta-style label), add the Callback URL from your Connector Profile
3

Select the OAuth scopes

Under Scopes, select every scope your integration needs. Use the selector below to pick the scopes — apply the same selection in DevPortal. Any scope you request at authorization time must be registered on the app, or the request fails. See ZoomInfo OAuth scopes for full descriptions.

4

Copy the Client ID and Client Secret

Save the app and copy both values from the Auth tab. Store them securely for use later.

​
Identity and access management token (Optional)

Unified IAM user actions read your users through ZoomInfo’s SCIM service, which uses its own API Token and Base URL. ZoomInfo offers them only after SAML single sign-on (SSO) is set up.

1

Generate the SCIM API Token

A ZoomInfo admin generates the token in the Admin Portal.

  • Go to Admin Portal > User Management > Users > Auto Provisioning and select the IdP tab
  • Choose a token expiration (90 days, 180 days or 1 year) and click Generate API Token
  • Copy the Base URL into the SCIM Base URL field and the API Token into the SCIM API Token field
  • The token stops working when its expiration period ends, so generate a new one and update this connection before then

​
Creating the StackOne Connector Profile

To create the Connector Profile in StackOne for ZoomInfo:
1

Open the connector

Log in to StackOne, open Connectors, and select ZoomInfo.
2

Choose actions and events

  • Click Add Profile.
  • If the connector offers more than one authentication method, set the Auth Method filter to OAuth 2.0 (Authorization Code + PKCE).
  • Select the actions, and any events, to enable for this Connector Profile.
  • Click Continue.
3

Set up authentication

  • Select Authentication Type as OAuth 2.0 (Authorization Code + PKCE).
  • Fill out the fields using details retrieved from your provider:
    • Client ID
    • Client Secret
    • Scopes (Optional)
  • Click Create Profile.
Congratulations! The new Connector Profile now shows up on the connector page. If you created it as a project member rather than an admin, it starts disabled until a project admin enables it. You can now continue to Link Accounts for ZoomInfo.
