What node are you using to receive this?

I'm gonna guess (due to lack of context or pictures or code) you're talking about the http in node?  
Attach a debug node set to output the whole message and see what you can gleen from the debug output. There will likely be a property that indicates this.

sorry, yes i use a http in node.  
I created a debug node, but do not see get or post in the header

As @Steve-Mcl said, try using a debug node set to show the whole message. The debug node is a Swiss Army Knife that will give you lot's of information about your flow. Have a look here:

For an http in you tell it what type to expect don't you? It's in the config.

Hi, I will give some detail info.  
In the included flow i support two ways from outsode to turn on a switch (see comment 3 and 4),  
So i can receive a http post with a body and a http het with variables in the http url.  
Both scenarios POST and GET have a different site to call  
http:\xxxx:xx\test and http:\xxxx:xx\test2  
The GET AND POST call have both partially different ways to create an MQTT message.  
What i want is that i can call my server with only ONE site url, by example  
http:\xxxx:xx\test (And NO http:\xxxx:xx\test2) for both POST or GET.  
After the call NODE-RED has to detect if it is a POST or GET to makes thinks work like they where separted...

Hope that this is info enough?

You should be able to configure separate nodes for the get and post, even though they are on the same address. That is what the Readme says anyway.

How about after the http in nodes, add change nodes & set msg.topic accordingly

FYI, The Http method that was used can be found in `msg.req.method`

Here is a `change` node JSONata expression trick that I like to use when I have an Http input endpoint with multiple (potential) input formats -- i.e. GET, POST, and/or inject a payload (for testing):

![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/2X/9/9cb83a4656f59ee67e3b8b248f6e8d68e8d81ef7.png)

The `$merge` function takes an array of objects and merges their properties into a single object. In this example, the payload fields are overwritten by any request params with the same name(s) from the POST request, which in turn are overwritten by the same named args on the query string -- of course, your use can may be different.

The big advantage is that the downstream flow does not need to know _how_ the input params were sent.
