-Appwrite lets you build integrations on web, mobile, native, and server platforms through a set of APIs. You can use one of our many SDKs or integrate directly through the REST API or GraphQL API.
+Appwrite lets you build integrations on web, mobile, native, and server platforms through a set of APIs. You can use one of our many [SDKs](/docs/sdks) or integrate directly through the [REST API](/docs/apis/rest) or [GraphQL API](/docs/apis/graphql).
 
 ## Client vs Server APIs {% #client-vs-server %}
 
 Client APIs and SDKs are for integrating with Appwrite to build client-based applications and websites. 
-They're authenticated with sessions and operate within the permissions granted to the user account used to create the session.
+Client APIs only give access to resources if users have been [granted permissions](/docs/advanced/platform/permissions).
 
 Server API and SDKs are for integrating with Appwrite to build backend or server applications.
-They're authenticated with API keys and are constrained by scope, ignoring user permissions.
+Server APIs are constrained by an [API key's](/docs/advanced/platform/api-keys) scope, ignoring user permissions.
 
-Choose the appropriate API and SDK for your use case.
+## APIs {% #api %}
+Before using the Appwrite APIs, in the **Settings** of your Appwrite project, obtain your **API endpoint** and **Project ID**.
+Client APIs require an active session, created from [signing up and logging in](/docs/products/auth/accounts##-login).
+Server APIs require [API keys](/docs/advanced/platform/api-keys).
