@the deal.... were you able to find out anything about the two?
Now how about pesapal vs jambopay vs kopokopo vs another?
Which can you vouch for?
I have worked with kopokopo but only for the mobile phone based transactions aka "lipa na mpesa".
But what about:-
1) an api supporting web integration?
2) Lowest charges.
3) Easy to implement
4) support widest range of payment options (Mpesa, airtel, yu cash, etc)
When I have money, I get rid of it quickly, lest it find a way into my heart.
