This section documents the **Blnk Core REST API.** It contains the endpoints your application calls to integrate with your running Blnk Core instance.
**Important to note:**
If you're using the auto-provisioned `Enterprise Core` instance included with your Production License, set the base URL to: `https://ENTERPRISE_PUBLIC_URL/core`.
Otherwise, use the publicly accessible base URL for your Core instance.
Each page lists the HTTP method, path, parameters, example requests, and response fields for one operation. To successfully call an endpoint, authenticate requests with your API key in the `X-blnk-key` header if set to secure mode.
If you are new to Blnk, start from the [documentation home](/), follow [installation](/home/install), then return here when you are ready to integrate.
Skip the manual setup and deploy your ledger in less than 1 minute on Blnk Cloud. No manual Docker, Postgres, or Redis setup required.
