I want to send data on an API from my PLC. Here is my flow: [{"id":"4fe68f34.52a3a","type":"function","z":"787783f2.48923c","name":"Send Data to API ","func":"msg.method = "GET";\nmsg.url = "https:/xyz.net/app/storeData?param1=" +(msg.payload.MoistureatReel)+"&param2=param2value&param3=param3value&param4=param4value&param5=param5value&param6=param6value&param7=param7value&param8=param8value&param9=param9value&param10=param10value";\nreturn msg; ","outputs":1,"noerr":0,"initialize":"","finalize":"","x":366,"y":252,"wires":[["2bb41ad7.354706"]]}] Instead of msg.payload.MoistureatReel what should I write/change so that the value at that PLC Variable we get here in that API.

Some info required to answer question what api? what plc? what is the incomming or input data? what should the finished url look like, is there an example? what values does the api take in the url? where is your flow? as you just supplied a single node.

[image] E1cid: what api? The values coming out of PLC are as shown in image below. PLC I am using is Siemens 1200, Input. It takes Data in any format i have manually wriiten values and send it but what should i write in place of " +String(msg.payload.MoistureatReel)+ " so that my value coming at parameter **[1] [2] ** reflects when i update this API.

[image] Swapnil: " +String(msg.payload.MoistureatReel)+ " msg.payload["Moisture at Reel"] as there are spaces in the name.

[image] Swapnil: " +String(msg.payload.MoistureatReel)+ " I have tried this but doesn't work

Try the format i showed below the quote.

[image] E1cid: msg.payload["Moisture at Reel"] It shows undefined

[image] Swapnil: parameter **[1] Not according to your image. You must have over written it. add debug before function to check it exists. I can not say more as i have no more info.

[7] [5] ![6|480x344] When i use like this "+context.global.MoistureatReel+" this thing works but i need to individually take 50 S7 Nodes 50 Function Nodes and write in the function nodes individually context.global.xxx which is not a feasable solution if there are more parameters to transfer

Again i ask for a debug from just before function showing complete message object.
