n8n · Connect your tools

Connect tunnelapi through an n8n HTTP Request node. Use dedicated credentials and execute one small request first.

Create a Header Auth credential: header name Authorization, value Bearer <your API key>. Select that credential in the node; keep the key out of workflow JSON and public template exports. Restrict access to n8n, encrypt credential storage and review execution-data retention.

Back up your existing configuration before editing. Merge settings rather than replacing the whole file. Never publish an API key or commit it to Git.

Download n8n workflow (.json)

Import the JSON into n8n, select your Header Auth credential and replace the model placeholder with an available model before running it manually. The workflow is inactive and automatic retries are disabled.
