## API Reference
- [Get a microsnippet response](https://docs.developers.optimizely.com/performance-edge/reference/get_microsnippet_reponse.md): Call the Edge Decider API to fetch a microsnippet.  Given the required arguments, the Edge Decider will bucket visitors into variations of active experiments they're qualified for and return the JavaScript microsnippet.  The microsnippet is executed by the browser to apply the variations' changes.  Note that for security, the Edge Decider API only supports connections made over HTTPS. It does not support connections made over insecure HTTP and responds with a 403 status instead.
