Integrate MessageBird OTP into your RedwoodJS app by installing the MessageBird Node.js SDK, setting up environment variables for your API key, creating necessary API services and frontend components, and updating your database schema to handle verification statuses. This guide provides a detailed walkthrough of the process, ensuring a secure and production-ready integration.

The MessageBird Verify API is a service that simplifies the process of sending and verifying one-time passwords (OTPs) for phone number verification. It handles generating OTPs, sending them via SMS or voice calls, and verifying user-submitted tokens, making it easy to implement two-factor authentication (2FA).

MessageBird offers a reliable and easy-to-use API for sending OTPs via SMS, enhancing the security of your RedwoodJS application. This helps prevent fraudulent accounts and provides an additional layer of security beyond passwords.

Phone verification is recommended during user signup, for high-security actions like changing passwords, or for account recovery. This adds an important layer of security to your RedwoodJS application, particularly useful for preventing fraud and unauthorized access.

Yes, you can customize the OTP message template using the `template` parameter when calling the MessageBird Verify API. Use the `%token` placeholder within your template string, which MessageBird will automatically replace with the generated OTP.

Handle MessageBird API errors by catching errors from the MessageBird SDK, logging the detailed error information using Redwood's logger for debugging, and then returning user-friendly error messages to the frontend. Map specific MessageBird error codes to customized user messages for improved UX.

The E.164 format is an international standard for phone numbers. It includes a '+' sign followed by the country code and the phone number, ensuring compatibility with global communication systems. For example, a US number would be formatted as +14155552671.

Store user phone verification status in your database using a boolean field, typically named 'phoneVerified.' Update this field to 'true' after successful verification via the MessageBird API. This guide shows how to update your Prisma schema to include this field.

Implement rate limiting to prevent abuse, use robust input validation, and protect against brute-force attacks. Ensure the verification process securely links to the correct user account. Never expose API keys in version control and always run your application over HTTPS.

Implement rate limiting using libraries like `rate-limiter-flexible` within your service or API function. Alternatively, use your deployment platform's API gateway features, such as those provided by AWS API Gateway or Cloudflare.

Robust input validation is crucial to prevent vulnerabilities and ensure data integrity. Validate phone numbers using libraries like `google-libphonenumber` to ensure they are in E.164 format and strictly validate the format of user-entered OTPs.

If the database fails to update after successful MessageBird verification, the user will be in an inconsistent state. Implement thorough logging to capture these errors and consider a robust retry mechanism or alert system to handle such scenarios. Manual intervention or support contact might be required.

Common troubleshooting includes verifying your API key, ensuring the phone number is in E.164 format, checking for token expiration, and implementing rate limiting to avoid request throttling. Consult the MessageBird documentation for specific error codes.
