I make post request to my api server, post using postman works very well but i can't make post request using node-red, please help need advice

```auto
msg.headers = {};
msg.headers={ 
      'Content-Type': 'application/json'
};

msg.method = "POST";
msg.url = "http://myserver:5000/datasensor";

msg.payload = {};
msg.payload = {
    "app_key":"41fd-bf8d-f558ee1cb84e",   
    "batt": raw.Bat,
    "level":raw.Level/100,
    "latitude":"0",
    "longitude":"0",
    "count":raw.fCnt,
    "temperature":"0"
 
  };

return msg;

```

How is the http request node configured?

It looks to me like your server does not accept/refusing post request with json body from node-red. How was the postman set up?  
Try

```auto
msg.payload = JSON.stringify(msg.payload);

```

I'ts strange as the request works at this test site to [https://ptsv2.com/t/7ybmy-1594053283/post](https://ptsv2.com/t/7ybmy-1594053283/post)

results can be seen here.  
[https://ptsv2.com/t/7ybmy-1594053283/d/6000863101321216](https://ptsv2.com/t/7ybmy-1594053283/d/6000863101321216)

Maybe there is some strange white space on your api key. Try deleting it and typing it in instead of copy and paste.

Or maybe node-red only works with https not http, that is right?

I would think that all you would do is back up your flows and settings json. Then when you upgrade if they need to be replaced then you have a copy.
