Hi,

I want to work with API PUT but it's necessary to give a JSON frame with it. How can I do that?

try switching your http-request node's Method to **PUT** and whatever `msg.payload` you send to it will be the body of the request.

Which node does I need to send the body and where must I place it ?

Your question is how to create a `msg.payload` which will be the body of the request ?  
to name a few .. you can use either an Inject, Change or Function node etc

What have you tried ? What is the JSON frame body of the request that you need to send ?

At this moment I have this script.

Your Flow cannot be imported .. use the Preformatted Text icon when you share code  
so it will be correctly formatted on the Forum.

Try this ..

```auto
[{"id":"55a991d4e79c0269","type":"inject","z":"54efb553244c241f","name":"inject data as Json","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"{\"mode\":\"NORMAL\",\"limit\":{\"unit\":\"PERCENTAGE\",\"value\":100}}","payloadType":"json","x":330,"y":1760,"wires":[["34016018192a8a7b"]]},{"id":"34016018192a8a7b","type":"http request","z":"54efb553244c241f","name":"Laadpaal sturen","method":"POST","ret":"obj","paytoqs":"body","url":"https://app1pub.smappee.net/dev/v3/servicelocation/59792/actuator/1/on","tls":"","persist":false,"proxy":"","authType":"bearer","senderr":true,"x":560,"y":1820,"wires":[["f905ccdb55bd2d80"]]},{"id":"f905ccdb55bd2d80","type":"debug","z":"54efb553244c241f","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","statusVal":"","statusType":"auto","x":750,"y":1820,"wires":[]},{"id":"ead31c6b5e54e5bb","type":"inject","z":"54efb553244c241f","name":"inject data as string","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"json={\"mode\": \"NORMAL\",\"limit\": {\"unit\": \"PERCENTAGE\", \"value\": 100 }}","payloadType":"str","x":330,"y":1880,"wires":[["34016018192a8a7b"]]},{"id":"377dc6d019125967","type":"comment","z":"54efb553244c241f","name":"OR","info":"","x":330,"y":1820,"wires":[]}]

```

(note that i changed the single quotes to double quotes for mode and NORMAL because single quotes are not valid Json)

better 😉

i shared in my last post a Flow for you to try ..  
( From the menu of the Node-red Editor you can select Import (or Ctrl-I) and copy paste to import and test )

By the way .. do you have any online documentation for your API ?

But on this moment I can't send a body with it. That's my problem, I don't know how to send the body (in json) with it

we understand the problem .. this is what we are trying to figure out 😉  
and i explained ways of sending a request body .. by sending your Json as part of the `msg.payload`

1. you didnt tell as if you tried the flow example i sent you in my previous post ?
2. from the documentation, which API method are you trying ? can you send us the exact link instead of the main page ? Is it the one with the Actuator ? [Actuator ON](https://smappee.atlassian.net/wiki/spaces/DEVAPI/pages/526647327/Actuator+ON)

Yes I tried your example but I receive error 405 even if I try to send it as a string  
the exact link: [https://app1pub.smappee.net/dev/v3/chargingstations/6000000046/connectors/1/mode](https://app1pub.smappee.net/dev/v3/chargingstations/6000000046/connectors/1/mode)  
json body: {"mode":"PAUSED"}

@UnborN I already found my problem, in the example was the method on 'Post' but it must 'Put'.

Thank you for the big help!

</div>

its important to share with us the correct links to the documentation of the API  
what we needed was this page : [Set the charging mode of one of the connectors of a charging station](https://smappee.atlassian.net/wiki/spaces/DEVAPI/pages/2803367937/Set+the+charging+mode+of+one+of+the+connectors+of+a+charging+station)

im glad it worked 👍
