@girish Yes, this was it. I did not manage to see the actual json. But seems like n8n always adds quotes using the name / value combination. I changed it to this:
{
"nodes": [
{
"parameters": {
"requestMethod": "POST",
"url": "=https://my.xxx.de/api/v1/notifications/{{$node[\"Item Lists\"].json[\"id\"]}}",
"jsonParameters": true,
"options": {},
"bodyParametersJson": "={\n\"acknowledged\": true\n}",
"headerParametersJson": "={\"authorization\": \"Bearer xxx\"}"
},
"name": "HTTP Request1",
"type": "n8n-nodes-base.httpRequest",
"typeVersion": 2,
"position": [
1100,
300
]
}
],
"connections": {}
}
Now it's working. I used this:
