Choose an integration tool
Users often ask when they should use scripts and when they should use the Microsoft Azure functionality.
Here are the essential points to consider:
You cannot use scripts to connect to other systems.
Scripts have certain restrictions. Check Script restriction and switch to an Azure function or external integration/code if necessary.
REST API and Web SDK
The SDK makes the REST API readily available and easy to use in the language for which the SDK is built.
If you are using another language, you should write your own implementation for the REST API.
Use the REST API/SDK if you want to connect to Sitecore Content Hub. It is not meant as a delivery mechanism, so you should not use it to perform a live integration. Indeed, Sitecore Experience Edge for Content Hub is available for that very reason and supports the requirements of a delivery mechanism.
