Troubleshoot Content Delivery API Errors

Common errors
404 - ContentNotFound when trying to get content with Content Delivery
- Do you enable the MultiSiteFilteringEnabled option? If enabled, the Optimizely Content Delivery API returns only the current site's contents based on the request's context.
- Do you use the correct Accept-Language header? Content Delivery API returns content based on the language passed in the Accept-Language header. Use the Accept-Language header to specify the locale variant of content that the client prefers (see Mozilla - MDN Web Docs for information). The problem is that some browsers, such as Chrome, automatically add their preferred language to the Accept-Language header if the user does not manually set the header value. In this case, the client should manually pass the Accept-Language header to prevent the browser from adding its header value. Using the Content Delivery API in an AJAX application, you can specify or override the Accept-Language header value in your front-end code. See this external blog post for a code sample.
