![]() ![]() ![]() You can use localhost to reference a function inside the same function app directly, without a roundtrip proxy request. You can condition it to use variables from the original client request, the back-end response, or application settings. The configuration for a proxy does not need to be static. The modified values can reference application settings, parameters from the original client request, and parameters from the back-end response.īack-end requests can be modified in the portal by expanding the response override section of the proxy detail page. You can make changes to the response's status code, reason phrase, headers, and body. Modify the responseīy default, the client response is initialized as a copy of the back-end response. The modified values can reference application settings and parameters from the original client request.īack-end requests can be modified in the portal by expanding the request override section of the proxy detail page. In addition to setting the back-end URL, you can make changes to the HTTP method, headers, and query string parameters. Modify the back-end requestīy default, the back-end request is initialized as a copy of the original request. These transformations can use variables as defined in Use variables. With Azure Functions Proxies, you can modify requests to and responses from the back-end. You can try out your new proxy by copying the Proxy URL and testing it with your favorite HTTP client. From a client perspective, it is equivalent to an HttpTrigger in Azure Functions. Your proxy now exists as a new endpoint on your function app. The value does not need to be static, and it can reference application settings and parameters from the original client request. This endpoint could be a function in another function app, or it could be any other API. ![]() Set the backend URL to another endpoint.These parameters behave according to the rules for HTTP triggers. Configure the endpoint that's exposed on this function app by specifying the route template and HTTP methods.Open the Azure portal, and then go to your function app.This section shows you how to create a proxy in the Functions portal. It provides the same capabilities as Functions Proxies as well as other tools for building and maintaining APIs, such as OpenAPI integration, rate limiting, and advanced policies. You should also consider using Azure API Management for your application. Proxies is available in Azure Functions versions 1.x to 3.x. ![]()
