Comunicate with External Software API when new Invoice is made

how can we make Syncro comunicate with a External Software API to send invoice details?

I would like to send Syncro invoices to WHMCS using the generate an invoice related to a service, GenInvoices API : [GenInvoices - WHMCS Developer Documentation]

How can this be done?

If anyone needs, got it working using and an external contractor. The Zapier integration from Syncro is broken and there is no ETA from Syncro.
