Actually I am using API to send SMS from a webpage from my site.
The SMS gateway site just gives the feedback of delivery, doesn’t return to my website.
After sending SMS, I need to send emails & update database.
I know JavaScript & php.
I don’t want to depend on SMS gateways redirection, is there a way to go to their webpage & return back without their involvement?
Call the API from your server using cURL and keep the client experience completly under your control – this way you not only can redirect, AJAX or whatever as much as you want, you can also doge some low-flying bullets with clients abusing your pages.
