To begin using the Productlane.com API, you’ll need to authenticate your requests. Start by obtaining your API key from the API settings page page. Here you’ll find your API key that you’ll need to authenticate the majority of your requests to the API. 
'Authorization': 'Bearer <API_KEY>'
Once you have your API key, you’ll need to add it to the requests you’ll be sending to the API. When making requests that require authentication, set the Authorization header to Bearer API_KEY, where API_KEY is the key you obtained earlier. That’s it! Now you’re ready to interact with the Productlane API.
