This is a complete SDK supporting all of The Fulfillment Lab's API functionality.
It was designed to be as simple as possible due to being needed in both a Magento 1.x and new Magento 2.x storefront. Permission was granted by the client to release under the LGPL license.
It has been tested as thoroughly as possible against a "dummy" endpoint mimicing TFL's API, however said client decided not to go forward with TFL's services so it has not been tested against their actual API - bug reports, patches, and suggestions are welcome.
This library is not supported or associated with The Fulfillment Lab themselves.
Requires Httpful which facilitates all communication with the API.
Requires PHPImapClient for scanning inventory from emailed reports.
Mainly self-explanatory. See tests.php for example code.
