Hello,  
I would like to show the the current petrol prices to my dashboard.  
For the data reference I use [this](https://github.com/jumpjack/distributori-benzina) link.  
He explains how can I configure a http request.  
For Example:

- Url: [https://carburanti.mise.gov.it/ospzApi/search/area](https://carburanti.mise.gov.it/ospzApi/search/area)
- Header: vuoto
- Payload:
  - region: ([numero](https://carburanti.mise.gov.it/ospzApi/registry/region)),
  - province: ([sigla della provincia](https://carburanti.mise.gov.it/ospzApi/registry/province?regionId=9) oppure null; il link di esempio fornisce l'elenco delle province della regione 9 (Lazio)),
  - town: ([nome del coumne](https://carburanti.mise.gov.it/ospzApi/registry/town?province=RM) oppure null; il link di esempio fornisce la lista dei comuni della provincia di Roma),
  - priceOrder: "asc" o "desc",
  - fuelType: "FuelType-RefuelingMode" (FuelType e RefuelingMode sono numeri (v. sotto))

Example of the header complete:

```auto
{ 
 "region" : 9, 
 "province" : "RM", 
 "town" : "Monterotondo", 
 "priceOrder" : "desc",
 "fuelType": "1-1",
 "refuelingMode" : 1
}

```

For my Node-RED project I found this as a possible solution:

[https://cookbook.nodered.org/http/set-request-header](https://cookbook.nodered.org/http/set-request-header)

I create this node, but unfortunately it doesn't work:

I hope somebody can help me.  
Thanks in advance.

Maybe something specific to your setup is the issue, describe your setup.

Do you get any errors returned?

Hello @E1cid,  
thank you a lot for your helpfulness and your quickly answer.  
I have no idea how long I've been trying around my code. I am all the more pleased that the code works. But why I get a request error every time I still have to look. I suspect it is due to my unstable WLAN connection ...:-/
