Custom applications that interact with the Karbon API will need your tenant's API access key before they can interact with your data. Here's how to find your Access Key:
1. Register your app.
If you haven't already done so head to https://developers.karbonhq.com and register your new app. Your app will need to have its registration approved before you can retrieve your tenant API access key.
2. Log in to Karbon and go to your connected apps settings
Log into Karbon as you usual, click Settings in the sidebar, then click Connected Apps
Find your custom integration and click "Manage"
Your access key will be displayed on the following page. Use this key in conjunction with your Application Authorization Token to interact with the Karbon API.
Remember to only give this access key to people and applications that you trust.
