  1. Replace {bandwidthApplicationId} with the real Application ID from the Bandwidth dashboard.
  2. Enable username/password authentication for both callbacks.
  3. Use the same callback user ID for the inbound and status callbacks.
  4. Use the same callback password for the inbound and status callbacks.

4. Location Setup

  2. On the Messaging tab, enable SMS using the HTTP API, Version 2.

6. Gather Required Credentials

  • Bandwidth API token and API secret

7. Prepare Test Accounts

Create Netsapiens test accounts, or provide existing accounts that Acrobits can use for testing.

8. Assign SMS Numbers to Test Accounts

Assign the newly allocated SMS numbers to the test accounts in the Metaswitch or Netsapiens portal.

If the test Metaswitch or Netsapiens accounts already have SMS numbers assigned, go to the Bandwidth dashboard and add those SMS numbers to the Location of the test Bandwidth application.
