I have an outbound application that sends SMS to customers.
In each SMS is a link to a web-page that they click on.
Each link is unique to each customer so that I can identify who they are.
I know there are short link tools around but I need to have a unique link for each customer.
Does Twilio have a nice solution for this? Or do I need to insert a long URL in each SMS.
Twilio developer evangelist here.
Twilio doesn't have an in built URL shortener for plain SMS (though this is an option when sending MMS messages).
I recommend using a URL shortening API, like the Bitly API. You can make a request to shorten your URL, then use the result when sending the SMS with the Twilio API.
