🔧 Authentication via HTTP headers

When authorizing requests with headers:

Header	Example Value	Notes
`Content-Type`	`application/json`	Required for JSON payloads
`X-GUID`	`6lC7NrMa4zw2v_fqFf-rQf`	Replace with your actual GUID
`X-API-KEY`	`iO6OZc37hEVTRgckKYphXAtt`	Replace with your actual API key

You can also authenticate by passing your credentials as query parameters:

GET /v1/customers?guid=6lC7NrMa4zw2v_fqFf-rQf&api_key=iO6OZc37hEVTRgckKYphXAtt
