API Key in URL

This is not a recommend method for security reasons! But some APIs still use it.

1. Under the field URL Token Extension on the Connector, add {{endpoint}}hapikey={{token}} where hapikey is the API key by the Connector

2. Add the below field in the header:

{
  "basic_auth": {
    "auth_token": {
      "title": "API Key",
      "type": "password",
      "required": true
    },
    ...
  }
}

The {{token}} is then replaced with the auth_token on each request and is not logged in Flow Debugging.
