Add credit to invoice using API

[Klangaroo]

If a customer has credit on their account, and they then generate an invoice, the credit doesn't appear to automatically be applied to the invoice. This is fine, as the user might want to save up their credit, but i do all of my interactions with WHMCS using the API and the database directly and there doesnt appear to be an API function for moving credit around. You can give a client credit, but you can't do anything with it.

 

Or can you? I can't work out how to apply a customer's existing credit to an invoice.

nevermind, i wrote my own function for it.

Klangaroo, would you mind either outlining the steps in your function or providing your function? I'm in the same pickle. I can add/subtract a clients credit via the API, but not apply the credit to an invoice. I too can drive that horse from the backend with a function but I just want to make sure my thoughts on doing this are similar/same to the direction you took.

 

Thanks,

Brad
