## Usage

Add as a dependency in any app that requires barriers, then do:

## Required Headers

In order to know which barrier to show and to call the Barrier API the following headers are required.  These are all set at the CDN level and will need to be spoofed if running locally.

* **FT-Barrier-Type** Set to a valid barrier type (eg 'TRIAL', 'PREMIUM' or 'CORPORATE');
* **FT-Access-Decision** Must be 'DENIED' or barrier will not show
* **Country-Code** Required by the API - set to any valid iso 3char country country-code (eg 'GBR')
* **FT-Content-Classification** Required by the API, can be any valid content classification (eg 'CONDITIONAL_STANDARD' or 'CONDITIONAL_PREMIUM')
* **FT-Session-Token** Required by the API - best off set to an empty string.  Otherwise needs to be a valid session with a relevant subscription status
