Callback URLs provide our messaging API with a location to accept new messages. You can find existing Callback URLs and set Callback URLs on your Manage > DID page.
To set Callback URL for your DID
Log into the Manage portal.
Navigate to the "DID" panel on the left side.
Under the tab "Manage" you have a list of available to you DIDs on the account.
To set a new Callback URL on a message-enabled DID, use the checkbox and select the DID you wish to update.
Above the DIDs there is a dropdown that has the "Select an Action" default displayed.
When you use the dropdown, under Messaging Options, you will find "Set Callback URL" option
Select that option and use the orange "Apply Action" button on the right to execute the selection on the checked DIDs.
You will be redirected to a new page where you will create a new Callback URL selection.
The checked DIDs will be noted above the Callback URL selection field.
Select the desired change to the Callback URL option.
