10. Define the following settings:

• Verification name: Enter the name of the configuration.
• OTP Length: Set the OTP length here.
• OTP Type: Select the type of the OTP (Numeric or Alphanumeric) from the OTP type drop-down menu.
• Interval between channels in seconds: Enter the time interval between the channels.
• Expiry time in seconds: Define the expiration time of the OTP here. The OTP expires beyond this time, and the user has to request a new one.
• Set this configuration as default: Select this option to set this configuration as default.

11. Click Publish.
    The Verification Configuration is created successfully, and you can see the same under the Configuration tab.

Configuration ID

Kaleyra.io will generate a unique ID called Configuration ID for every configuration. This ID acts as a reference and executes the configuration as per the settings when you pass it through the generated OTP API.

Generate OTPs

Now that you have configured the verification flow, you should execute the Generate OTP API command with the Flow ID to generate and send the OTP.

Validate OTPs

You can verify the status of the OTP through either Validate OTP API or the Kaleyra.io console. The Dashboard tab in the Verify page displays the real-time data of the number of OTPs sent, delivered, and verified by the users.
