[FIXED] How to find relation between send and received message in twillio

Issue

I am using Copilot API of twillio to send sms. so i am able to send sms to end user. Now if user reply to that sms, i am receiving the callback (PHP Script). Using that callback URL, i am able to get the reply message.

Now i want to do is, i am trying to find a relation between sent and received(which end user reply) message. so i can then forward the reply message to their sender.

I will have UI like below, where user enter the message and number where he wants to receive reply.

But the problem is i am not able to find relation between send/receive message.

Any advice will be helpful.

Solution

Twilio developer evangelist here.

Other than storing the information on your server upon sending/receiving a message, you could make use of the cookies stored at Twilio.

When Twilio makes a request to your server and it returns a cookie (a Set-Cookie HTTP response header), Twilio stores this cookie and associates it with the From and To numbers for the incoming call or SMS message.

A little caveat to this is the fact that this cookie is only stored for four hours, so unless that works for you, I'd suggest using the from & the to as composite keys to find a relation.

Hope this helps you
