Hi Ivan,
Do you mean get currency exchange rates from your local bank API instead of APIs we have in the plugin? If that’s the case, yes, generally that’s possible. There is alg_wc_pgbc_server_rates_function
filter you could use, but obviously, you’ll need to add a PHP snippet for this to work. Please let me know if you need more info about the filter. Also, if you wish, please let me know where I can check your local bank’s API – I could either provide you a snippet or maybe even add your bank to our plugin directly.
P.S. You can contact me directly at [email protected].
