ALL

I use the http request node to instruct a system to do something

where single command is used it work fine.  
[http://192.168.1.11:11111/api/v1/telescope/0/unpark](http://192.168.1.11:11111/api/v1/telescope/0/unpark)

But the question is how to deal with the following http string

[http://192.168.1.11:11111/api/v1/telescope/0/slewtocoordinatesasync](http://192.168.1.11:11111/api/v1/telescope/0/slewtocoordinatesasync)" -H "accept: application/json" -H "Content-Type: application/x-www-form-urlencoded" -d "RightAscension=0&Declination=90&ClientID=&ClientTransactionID="

the following is not working

```auto
[{"id":"4162b8d3.6fadb8","type":"ui_button","z":"55c1b3dc.91214c","name":"Goto ZeroPosition","group":"8e238b13.7c40b8","order":14,"width":0,"height":0,"passthru":false,"label":"<font size=\"+1\">Goto ZeroPosition</font>","tooltip":"","color":"","bgcolor":"","icon":"","payload":"","payloadType":"str","topic":"","x":190,"y":840,"wires":[["8932f8e.c5c8888"]]},{"id":"8932f8e.c5c8888","type":"http request","z":"55c1b3dc.91214c","name":"","method":"PUT","ret":"txt","paytoqs":"ignore","url":"http://192.168.1.11:11111/api/v1/telescope/0/slewtocoordinates -d \"RightAscension=0&Declination=90\"","tls":"","persist":false,"proxy":"","authType":"","x":390,"y":840,"wires":[[]]},{"id":"8e238b13.7c40b8","type":"ui_group","name":"ALPACA","tab":"dd962aa5.a268f8","order":2,"disp":true,"width":"8","collapse":true},{"id":"dd962aa5.a268f8","type":"ui_tab","name":"OCS","icon":"dashboard","order":1,"disabled":false,"hidden":false}]

```

Look at [this post](https://discourse.nodered.org/t/best-way-to-run-a-curl-command/29594/7) where I demonstrate how to break down a curl to a request.

Try

```auto

thanks

this is working via the command line  
curl -X PUT "[http://192.168.1.11:11111/api/v1/telescope/0/slewtocoordinatesasync](http://192.168.1.11:11111/api/v1/telescope/0/slewtocoordinatesasync)" -H "accept: application/json" -H "Content-Type: application/x-www-form-urlencoded" -d "RightAscension=0&Declination=90"

`http://192.168.1.11:11111/api/v1/telescope/0/slewtocoordinatesasync?RightAscension=0&Declination=90&ClientID=&ClientTransactionID=`  
unfortunately this is not working

and what is wrong with the payload below

```auto
[{"id":"37d01ae9.869d66","type":"change","z":"55c1b3dc.91214c","name":"","rules":[{"t":"set","p":"headers","pt":"msg","to":"{\"accept\": \"application/json\" }","tot":"json"},{"t":"set","p":"headers","pt":"msg","to":"{\"Content-Type\":\"application/x-www-form-urlencoded\"}","tot":"json"},{"t":"set","p":"payload","pt":"msg","to":"{\"RightAscension=0&Declination=90\"}","tot":"json"}],"action":"","property":"","from":"","to":"","reg":false,"x":280,"y":900,"wires":[[]]}]

then try adding the data as the body using msg.payload. and setting the headers.

Here is a demo using what I think you might ultimately need (variable values for the RightAscension and Declination)...

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/8/d/8d7b080877ce184c464c9a836f8ea250dde857a1.png)

↑ obviously the requests dont work for me.

the demo flows...

There was also thinking falure which i didn't account when the telescope is parked you cant slew you need first unpark the telescope.

This is is the new way ho to communicated with telescope with Alpaca  
[ascom alpaca api](https://ascom-standards.org/api/)  
#ASCOMALPACA #ALPACA

this are the items i have implemented yet i will share it below so others can use it also.
