Dear ALL, I am a newer of zoom and have some questions need help. 1. Is developer account free ? 2. What’s the difference between API and SDK ? 3. Should the develper account have to buy some hosts before testing ? Can the client built with SDK be used in all of world ? Thank for your help! ---

Hey @arrayxs, > [@arrayxs](#): > > Is developer account free ? Some of our APIs are available for free, you can see the prerequisites on each endpoint page. > [@arrayxs](#): > > What’s the difference between API and SDK ? The [Zoom API](https://marketplace.zoom.us/docs/api-reference/introduction) is a REST API to take actions on Zoom accounts. The [Zoom SDK](https://marketplace.zoom.us/docs/sdk/native-sdks/introduction) is for embedding Zoom Meetings / Webinars into your Website or Application. > [@arrayxs](#): > > Should the developer account have to buy some hosts before testing ? Depends on your use case! > [@arrayxs](#): > > Can the client built with SDK be used in all of world ? Yes, except for these countries: [https://support.zoom.us/hc/en-us/articles/203806119-Will-Zoom-Work-Internationally-](https://support.zoom.us/hc/en-us/articles/203806119-Will-Zoom-Work-Internationally-) Thanks, Tommy ---

Hi Tommy, Another questions: Where to find SDK document ? If SDK has new version, Does client built with old version still work ? Thank a lot. ---

Hey @arrayxs, > [@arrayxs](#): > > If the account’s Zoom Meeting Plan was stopped for several months,then contiue to renew. Can the SDK client still work ? What do you mean? If the user was switched to a basic free plan? > [@arrayxs](#): > > Where to find SDK document ?
