For you to init your SDK and interact with Appwrite services you need to add a web platform to your project. To add a new platform, go to your Appwrite console, choose the project you created in the step before and click the 'Add Platform' button.
From the options, choose to add a **Web** platform and add your client app hostname. By adding your hostname to your project platform you are allowing cross-domain communication between your project and the Appwrite API.
Once your SDK object is set, access any of the Appwrite services and choose any request to send. Full documentation for any service method you would like to use can be found in your SDK documentation or in the [API References](https://appwrite.io/docs) section.
