mittwald

Overview

This node operation verifies a user's phone number by submitting a verification code along with the phone number and user identifier. It is useful in scenarios where you need to confirm that a phone number belongs to a specific user, such as during account setup, two-factor authentication, or phone number updates.

Practical examples:

• Confirming a new phone number entered by a user before enabling SMS notifications.
• Verifying a user's identity by requiring them to enter a code sent via SMS.
• Ensuring phone number ownership in user management workflows.

Properties

Output

The node outputs JSON data representing the result of the phone number verification request. This typically includes confirmation of success or failure and may contain additional metadata about the verification status.

No binary data output is indicated.

Dependencies

• Requires an API key credential for authentication with the mittwald mStudio API.
• The node communicates with the mittwald API endpoint at https://api.mittwald.de.
• Proper configuration of the API credential within n8n is necessary for successful requests.

Troubleshooting

• Invalid or expired verification code: If the code is incorrect or expired, the API will reject the verification. Ensure the user inputs the correct, most recent code.
• Incorrect user ID or phone number format: Validation errors can occur if the user ID is invalid or the phone number is not in international format.
• Authentication errors: Missing or invalid API credentials will cause authorization failures. Verify that the API key is correctly configured.
• Network issues: Connectivity problems can prevent the node from reaching the API endpoint. Check network access and proxy settings if applicable.
