### [Read this on the main serverless docs site](https://www.serverless.com/framework/docs/providers/azure/events/http) # HTTP Trigger Azure Functions has an API endpoint created for each Function App. This service allows you to define public HTTP endpoints for your serverless functions. To create HTTP endpoints as Event sources for your Azure Functions, use the Serverless Framework's easy HTTP Events syntax. It might be helpful to read the Azure Function [HTTP Trigger docs](https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-http-webhook) to learn the full functionality. ## HTTP Trigger Events ### Simple HTTP Endpoint This setup specifies that the `hello` function should be run when someone accesses the Function App at `api/example/hello` via a `GET` request. Here's an example: ```yml # serverless.yml functions: example: handler: handler.hello events: - http: true name: req #, default - "req", specifies which name is available on `context.bindings` methods: # [GET, POST, PUT, DELETE], default - all - get route: example/hello #, default - authLevel: anonymous # ``` URL paths for the serverless functions are prefixed with "api" by default, e.g. `/api/some/path`. You can change this via a setting in [host.json](https://github.com/Azure/azure-webjobs-sdk-script/wiki/host.json). ```javascript // handler.js 'use strict'; module.exports.hello = function (context, req) { context.res = { body: 'Hello world!', }; context.done(); }; ``` ### Request event You can see the [full docs for HTTP triggers](https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-http-webhook#http-trigger-sample-in-nodejs) to learn all the capabilities. In Node.js, the request object looks like an express request object. ```javascript // handler.js 'use strict'; module.exports.hello = function (context, req) { const query = req.query; // dictionary of query strings const body = req.body; // Parsed body based on content-type const method = req.method; // HTTP Method (GET, POST, PUT, etc.) const originalUrl = req.originalUrl; // Original URL of the request - https://myapp.azurewebsites.net/api/foo?code=sc8Rj2a7J const headers = req.headers; // dictionary of headers const params = req.params; // dictionary of params from URL const rawBody = req.rawBody; // unparsed body context.res = { headers: { 'content-type': 'application/json', }, body: { hello: 'world', }, }; context.done(); }; ``` #### Webhook > NOTE: Webhook is a version 1.x feature. Version 2.x runtime > no longer include > built-in support for webhook providers. If you specify WebHook, you'll get passed the body as the second argument to your Function, not the request object. You can still access the request object on the context object (i.e. `context.req`) ### CORS Support You can set up CORS following the instructions on [azure.com](https://docs.microsoft.com/en-us/azure/azure-functions/functions-how-to-use-azure-function-app-settings#manage-cors).
