Verify Now

Start by deciding where identity checks fit in your app: sign-up, sign-in, or sensitive actions like payout changes. In Verify Now, create an API key, set your code length and expiry, and draft a concise message template that includes your brand and a clear time limit. Map your screens: request code, enter code, and success/failure. For web, trigger SMS from your server to keep credentials off the client. For mobile, call your backend first, then the Verify Now endpoint. Add rate limits per user and device to prevent spam and set a short resend cooldown.

Developers can wire the basic flow in a morning. Use a server route to call the send-code endpoint with the user’s phone and a reference ID. Log the response ID so you can trace any delivery questions later. When the user submits the code, hit the verify endpoint with that reference ID and the code; on success, issue your session token and mark the phone as confirmed. Handle common errors: expired code (prompt a new one), too many attempts (delay and show a safe retry window), mismatched code (increment a soft counter). Separate sandbox and production keys, and seed test numbers to automate QA. For international audiences, maintain templates per locale and set expiry windows that match typical delivery times in each region.

Operations teams can handle peaks and rollouts with the bulk interface. During a migration or a new product launch, upload a vetted list and schedule sends by cohort to avoid sudden traffic spikes. Use delivery callbacks to track latency and completion; route users who don’t receive a code within your target window to a guided resend. Monitor key metrics: delivery rate, time-to-first-code, verification completion, and resend ratio. If you see slow delivery in a region, temporarily extend the expiry and adjust resend wait times. Keep your templates short to reduce carrier filtering, and avoid links unless your compliance team approves them.

Security and product managers can harden the flow without adding friction. Set global and per-user attempt caps, block numbers with repeated failures, and enable IP allowlisting for your admin tools. Rotate API keys on a schedule and restrict who can view phone numbers in logs. Use audit trails to review changes to templates, keys, and rate limits. For growth and UX, A/B test message copy, code length, and expiry to balance speed and safety. Customer support can trigger a single-use verification for account recovery, with limited lifetime and no reuse. Finally, export daily reports to your BI stack to correlate verification health with sign-up conversion, chargeback rates, and support volume.
