  6. Handle network errors and timeouts for OTP requests

    When dealing with network failures or timeouts during OTP service calls, follow these best practices:

    1. Retry Logic: Implement a retry mechanism using exponential backoff.
    2. Timeout Configuration: Set a request timeout (recommended: 30 seconds).
    3. Logging: Log all errors to facilitate debugging.
  7. Understand the Ibtikar OTP authentication workflow

    The OTP authentication process follows a four-step workflow:

    1. OTP Request: The user requests a verification code.
    2. Reception: The user receives the code via SMS or WhatsApp.
    3. Submission: The user submits the received code for verification.
    4. Validation: The system verifies the code and confirms the user's authentication.
  8. Implement security best practices for OTP integration

    When integrating the OTP service, follow these security guidelines:

    1. Client-side Validation: Validate the phone number format before sending the request to the API.
    2. Transport Security: Use HTTPS for all API requests.
    3. Secure Storage: Never store OTP codes in plain text.
    4. Expiration Management: Handle token expiration logic on the client side.
    5. Audit Logging: Log verification attempts to monitor for security anomalies.
  9. Handle OTP delivery channels and restrictions

    The service supports two delivery channels with specific constraints:

    1. SMS (Default): Used for national (Mauritania) and international numbers (via Twilio).
    2. WhatsApp: Available only for international numbers. Mauritanian numbers (+222) located in Mauritania cannot receive OTPs via WhatsApp; the system verifies this automatically via the provided IP address.
  10. Handle OTP network errors and code formats

    To manage network errors, implement retry logic with exponential backoff and an appropriate timeout. Regarding code format: OTP codes may contain zeros, but they will never start with a zero.
