To create a digit collector in an active voice call, follow the steps below

1. Create an active voice call

Request:

curl -X POST \

  https://api.syniverse.com/scg-external-api/api/v1/calling/calls \

  -H 'Authorization: Bearer <TOKEN>' \

  -H 'Content-Type: application/json' \

  -d '{

    "from": "USfmJmPpEw4uXRjdQfN9J4",

    "to": "+14085551212"

}'

               Response: {"id": "dX9qqkH0b2UPEBL0WBsCz6"} - Active call ID

 2. Create Digit collector

Using the response id from the Active Call, submit a Digit collector call

curl -X POST \

        https://api.syniverse.com/scg-external-api/api/v1/calling/calls/dX9qqkH0b2UPEBL0WBsCz6/digits_collector \

        -H 'Authorization: Bearer <Token>' \

        -H 'Content-Type: application/json' \

         -d '{"max_digits":"10","terminating_digits":"#","timeout":"15","prompt":{"sentence":"<speak><prosody rate=\"slow\">Hello, please type your passcode digit and press #</prosody></speak>","voice":"matthew"}}'

               Response {"id": "9M5HBv1LIXTv1BLDCz6iL1"}  - collector ID

Please note that "#" is the only supported value for the "terminating_digits" parameter.
