I am simply briefing the project:
When a user subscribe to my site, the process is:
1. my system identifies the user's msisdn (user mobile number) from the header
2. after he presses subscribe button, we redirect him to 3rd party consent page called SDP
3. From there if he presses "YES" then he come backs to our site and his details are stored in a table of mysql
After the change, it will be:
1. my system identifies the user's msisdn (user mobile number) from the header
2. after he presses subscribe button, we will redirect him to OTP page (you have to create it to let the user put OTP code that we sent in his sms inbox)
3.In the background, we will enter data of the user's msisdn and other in another table of mysql so that he gets the sms
4. OTP code will be valid for 5 minutes. After successful OTP verification, we redirect him to 3rd party consent page called SDP
5. . From there if he presses "YES" then he come backs to our site and his details are stored in a table of mysql as happened
