Notifications & Webhooks

Because audio and video transformations are relatively intensive, they can take a few minutes depending on the length of the clip. The first call you make to the API initiates the transformation. Each subsequent call you make for the same task will return the current status—handy if you need to update your UI or application as the process continues.

Once the audio transcoding has completed, a webhook will be sent to notify your application.
