Hi, I need make node with more input value for example temp1,temp2,temp3,temp4 join and send in one http get. I have joined all values to one, but I dont know how to rename each payload to exact name and use in http get url....

www.aaa.com/index.php?temp1=(here value from temp1)&temp2=(here value from temp2)&temp3=(here value from temp3)&temp4=(here value from temp4)

example...

www.aaa.com/index.php?temp1={{temp1}}&temp2={{temp2}}&temp3={{temp3}}&temp4{{temp4}}

You message should contain these values e.g.

msg.temp1 = "i am a query parameter"
msg.temp2 = "i am another query parameter"
msg.temp3 = "something"
msg.temp4 = "something else"
return msg

Hi Steve,
Yes, I know this, but i need help with something "before" http request...
I got the values from mqtt, have 4 mqtt probes with output (TMP_1) (TMP_2) (TMP_3) (TMP_4) - (need convert name from TMP_1 to temp1 when send over http get), next use join for one value output and after them ? Maybee is "join" function wrong, I dont know, because I am newbile...
Thanks

Which is it?

Maybe you should share a demo flow (select nodes of interest, CTRL-E export, paste into reply)

For the record,

If the values come from separate nodes (down different wires) you need a join node.

Once you have all value inside 1 msg, you can do whatever you need to - to form a URL.

Show us what comes out of your join node too.

So your values are in msg.payload.TMP1, msg.payload.TMP2 and msg.payload.TMP3

Then why not simply use them!

Put www.aaa.com/index.php?temp1={{payload.TMP1}}&temp2={{payload.TMP2}}&temp3={{payload.TMP3}} in the url field of the HTTP request node!

Work, thank !
