+### Remove "This message was sent automatically by n8n" signature from Telegram messages
+
+**Problem:** n8n Telegram node adds attribution signature to all messages by default.
+
+**Solution:** Use the correct parameter name `appendAttribution` (camelCase, not snake_case) in `additionalFields`:
+
+```bash
+# Get workflow
+curl -H "X-N8N-API-KEY: $(cat /tmp/n8n-key.txt)" \
+  http://10.10.10.207:5678/api/v1/workflows/WORKFLOW_ID > workflow.json
+
+# Update all Telegram nodes (using jq)
+cat workflow.json | jq '.nodes = (.nodes | map(
+  if .type == "n8n-nodes-base.telegram" then
+    .parameters.additionalFields.appendAttribution = false
+  else
+    .
+  end
+))' | jq '{name, nodes, connections, settings, staticData}' > workflow-fixed.json
+
+# Upload updated workflow
+curl -X PUT \
+  -H "X-N8N-API-KEY: $(cat /tmp/n8n-key.txt)" \
+  -H 'Content-Type: application/json' \
+  -d @workflow-fixed.json \
+  http://10.10.10.207:5678/api/v1/workflows/WORKFLOW_ID
+
+# Restart n8n to reload workflow
+ssh docker-host2 'cd /opt/n8n && docker compose restart n8n'
+```
+
+**Important Notes:**
+- Parameter must be `appendAttribution` (camelCase), not `append_attribution` or `append_n8n_attribution`
+- Must restart n8n after updating workflow for changes to take effect
+- This applies to all Telegram message nodes in the workflow
+
+**Fixed:** 2026-01-23
