 Use [Apollo.io](https://apollo.io/) in Sim to search and enrich people and companies, manage CRM contacts and accounts, add contacts to sequences, and create follow-up tasks. Single-record and bulk enrichment operations are documented below.
+
+Connect an Apollo account with OAuth, or save an API key as an Apollo credential. Existing API-key connections and workflows continue to work. OAuth requires an Apollo administrator or a user with permission to authorize third-party apps. Your Apollo plan, permissions, and credits still apply.
+
+For self-hosting, register a public partner OAuth app in the [Apollo developer portal](https://developer.apollo.io/), configure `APOLLO_CLIENT_ID` and `APOLLO_CLIENT_SECRET`, and register `https://<your-domain>/api/auth/oauth2/callback/apollo` as a redirect URL. Enable the scopes listed below. API-key credentials remain available without an OAuth client.
 {/* MANUAL-CONTENT-END */}
 
+## OAuth scopes [#oauth-scopes]
+
+Sim requests these scopes when someone connects an Apollo account. For a self-hosted deployment, register your own app with the provider using the settings below. See [Integrations and OAuth](/platform/self-hosting/integrations-oauth) for setup.
