Hi @Zabwino1865,

The presence of this message is something which has been reported to us previously, and case CORE-11887 is open with our development team to clean it up in a future update.

Our investigations have determined this message isn't actually indicative of any functional problems, so can safely be ignored in the meantime.

Hi!

Will this be solved some day? This issue is giving me a lot of trouble.

A have an external checkout page which uses WHMCS API (addorder) to create orders in WHMCS.

When the order total is equal zero, the system automatically tries to run the create module function. In fact the account is created at cPanel but then this error is reported in WHMCS Log: "Application Link Provisioning returned the following warnings: API failure: Provide the “app” parameter for the “Whostmgr::API::1::Integration::create_integration_link” function. XIDs: pbt5s6"

Everytime is the same problem. Despite of this error, the create module function is running fine, order/invoice is created in WHMCS, almost everything is ok. The only and worst thing is that my WHMCS API call returns just an empty string. It doesn't return a satisfying answer. Not a "result=success", "result=error", nothing but an empty string. It should be handled by the API, specially because everything is being created correctly.
