Help to send notifications contents to a webhook

[lordraiden]

I need help creating the script to send the ouput of the notifications to a webhook. I am getting parsing errors.... Can someone help me please?

/usr/bin/curl -X POST \
  -H "Content-Type: application/json" \
  -H "X-N8N-TOKEN-NOTIFICATION: aaa" \
  --data-binary '{"summary": "{{ .Summary }}"}' \
  "https://n8n.test.es/webhook/f70542ed-645e-42f6-91e3-18606b9c6257"

This is the output

[script] [sh]
[script] /usr/bin/curl -X POST \
[script]   -H "Content-Type: application/json" \
[script]   -H "X-N8N-TOKEN-NOTIFICATION: aaa" \
