API Keys are required for HTTPS only connections

In addition to corporate code and passcode, partners must authenticate their requests with an x-api-key header provided by MFS Africa, as shown below.

x-api-key: TPToIddFi4IAMF33w

A request submitted without the MFS API key receives the following error.
