Hello sir,
Reference your inquiry we would like to inform you that we have already worked on this system earlier and have successfully integrated it, and its working fine for more than a period of 5 months since we finished integrating.
For the system to implement properly, we will need to contact the short code provider or you can also communicate with them on our behalf as we will need them to define some rules on the server.
Also we will need the complete source files to implement it.
Looking forward to your valued response.
Regards,
OK Team
