Gusto

OAuthHR & OpsOrg connection

Org-level connection

Gusto is connected once at the org level by an admin. The credential is shared across all groups that have been granted access — individual team members don't need to connect their own accounts.

How to connect

Click "Connect with OAuth" below to authorize On Belay to access your Gusto account. You'll be redirected to Gusto to approve the connection — no credentials to copy or paste.

Note: Only the primary admin or a full-access admin of the Gusto company can authorize this connection. Gusto also requires developer approval before production access is granted.

Permissions (scopes)

These are the data scopes On Belay can be granted for Gusto. Your org admin controls which scopes are enabled per group.

Scope	Description	Access
`employees:read`	Read employees	Read only
`payroll:read`	Read payroll	Read only
`benefits:read`	Read benefits	Read only
`company:read`	Read company info	Read only

Troubleshooting

"redirect_uri_mismatch" error during OAuth

Your OAuth app's authorized redirect URIs don't include the On Belay callback URL. Add https://app.onbelay.ai/api/oauth-callback/gusto to the allowed redirect URIs in your OAuth app settings.

"invalid_scope" error

The API or scope isn't enabled in your cloud project. For Google integrations, make sure the relevant API (e.g. Google Ads API, Search Console API) is enabled in Google Cloud Console for your project.

Connected but Claude can't access data

Check that your group has been granted access to this integration in On Belay → Groups → [your group] → Integrations. Also verify the specific scopes your group is permitted to use match what your query requires.
