You must first create an API key in the ADI OtoSense SMS UI. To do this, you must be an administrator of your ADI OtoSense SMS tenant. This is a one-time operation. You will be provided with a Client ID and a Client Secret. Please note this information down, as it will be required for the next step. The Client ID and Client Secret should be considered sensitive credentials and thus should be secured appropriately, never use them in front end single page applications, never commit them to source code or otherwise make them generally accessible.
Note: The API key will be governed by the assigned user role. The operations available to the key will be determined by this role.
