Kayako Fusion Module
Currently, unless I'm mistaken, WHMCS 5.x and Kayako Fusion do not work properly without a Third Party or custom designed module. This presents problems for upgrading WHMCS or Kayako if both are being used in the support ticket process.
To my knowledge there are only two options available to resolve this issue:
1. Buy a customized module from a Third Party provider which seems flaky.
2. Create your own module to integrate the two platforms together. A nice feature to have would be a new integration module that works with Kayako Fusion in the way that WHMCS works with Kayako v3. Why should we have to pay for a third party module or spend time creating our own module when WHMCS used to offer this for free?Just a thought.
