You can use Exotel's SMS API to shorten a long URL in SMS and you can track customer's click data as well. Shortening a long URL will also reduce the number of characters in SMS and allow you to stick to the 160 characters limit for SMS. Follow steps below to set it up:


1. Get in touch with your Account Manager or drop an email to "[email protected]" to enable URL shortening services for your account 


2. While making the API Request to send SMS, make below changes to your SMS request -

  1. Set Parameter "ShortenUrl" -  'true' if you want to shorten a URL, To provide flexibility, we allow you to set it to 'false' as well don't want to shorten any particular SMS.

  2. Set Parameter "ShortenUrlParams[CustomDomain] " - with the custom domain you want the short URL to start with. If custom domain is not present or empty, we will use the default domain(exo.tl), If custom domain is given in the request it will be used to form the short URL . Note : Clients will have to route the traffic on their custom domain to exo.tl domain, this is a change on your domain management system

  3. Set Parameter "ShortenUrlParams[Tracking] " - 'true' if you want to track data when a customer clicks on the URL. This feature is currently available to select customers.
