Here's an example. Hope it helps

[{"id":"8367f315.5045f8","type":"inject","z":"4484ee28.caa3c","name":"","topic":"startdate","payload":"124","payloadType":"str","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":120,"y":360,"wires":[["5266085a.2568f8"]]},{"id":"51495b9b.dec9f4","type":"inject","z":"4484ee28.caa3c","name":"","topic":"enddate","payload":"123","payloadType":"str","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":140,"y":420,"wires":[["5266085a.2568f8"]]},{"id":"5266085a.2568f8","type":"join","z":"4484ee28.caa3c","name":"","mode":"custom","build":"object","property":"payload","propertyType":"msg","key":"topic","joiner":"\\n","joinerType":"str","accumulate":false,"timeout":"","count":"2","reduceRight":false,"reduceExp":"","reduceInit":"","reduceInitType":"","reduceFixup":"","x":330,"y":380,"wires":[["b6f9a794.7feec8","5fcee44d.821854"]]},{"id":"5fcee44d.821854","type":"change","z":"4484ee28.caa3c","name":"","rules":[{"t":"set","p":"payload.datapoint","pt":"msg","to":"123456","tot":"str"}],"action":"","property":"","from":"","to":"","reg":false,"x":520,"y":440,"wires":[["6d7c0132.1dcd6"]]},{"id":"6d7c0132.1dcd6","type":"http request","z":"4484ee28.caa3c","name":"","method":"GET","ret":"txt","paytoqs":true,"url":"http://192.168.1.10:8765","tls":"","persist":false,"proxy":"","authType":"","x":660,"y":380,"wires":[["b6f9a794.7feec8"]]}]

The answer is in the help. You can feed an object via the payload, tick the option in the request node and the object will be converted to parameters for you without needing to faff with a template.

The key point however is the different values are coming from different messages - they don't all appear in one message arriving at the request node.

This is what the example from @E1cid shows - using a join node to get the separate messages combined into one that can be passed to the request node.

thanks.~ for your help~

hi guy , i now worked ok , but what i do is to set the topic in each payload , and use the JOIN method mentioned by @E1cid.
here is what i do here:
