Webhooks are one of the best ways to connect other applications with SMSto - especially when the communication and events between those are happening asynchronously.

Instead of app A having to constantly query app B if a certain even in B has occurred or not, A will just be listening for webhooks from B. B will actively give a signal towards A that an event in B has happened. The webhook can include additional information about the event. for example whether a message sent via our API was delivered successfully or not.

Using webhooks for this purpose reduces unnecessary overhead and makes sure that the communication happens directly after the underlying event has occurred.
