 ## Incoming HTTP requests
 
-All HTTP requests are handled by the ICP HTTP Gateway, therefore you cannot make direct `POST` calls to a canister's `http_request_update` method with HTTP clients such as curl. Instead, you can make a `POST` call to a canister's HTTP endpoint, then configure the canister's `http_request` method to [upgrade the call to `http_request_update`](/docs/current/references/http-gateway-protocol-spec#upgrade-to-update-calls). Below is an example `POST` call to a canister's endpoint:
+Every HTTP request first goes to `http_request`, and only if you return `upgrade: true` will it be upgraded and re-called as `http_request_update`. The HTTP method (`GET`, `POST`) does not matter.

-curl -X POST -H "Content-Type: application/json" -d '{"key":"value"}' https://<canister-id>.raw.ic0.app/<endpoint>

 ## `POST` requests
 
-HTTP `POST` requests are used to send data to an endpoint with the intention of retaining that data. To handle incoming `POST` requests, the `http_request_update` method can be used. This method uses an `update` call, which can be used to change a canister's state. The following examples display how to configure `http_request_update` method within your canister.
