Authentication

Sync API is built on top of Delivery REST API. If you enable secure access for Delivery REST API or want to sync changes in preview content, you need to authenticate your synchronization requests with a valid Delivery API key.If your use case requires authentication, send your sync requests over HTTPS and use the Authorization header in the following format: Authorization: Bearer <YOUR_API_KEY>. To create and manage your API keys, go to Kontent.ai > Project settings > API keys. Requests with an incorrect or missing Authorization header will fail with an error.
Format: Bearer <YOUR_API_KEY>
