When a user doesn't receive an SMS with a code during registration, it's not just an error—it's a lost customer. According to SMS.RU data, 30% of users abandon the form if the OTP doesn't arrive within 30 seconds. Another 15% of orders are canceled without SMS confirmation. Integrating with a reliable provider like SMS.ru solves these problems and reduces churn. We connect SMS.ru to your website built on Laravel, Django, Rails, or any other framework. Our stack includes PHP 8.3+, Node.js, Go—we adapt to any architecture. Let's dive into the technical details.
How to Integrate SMS.ru in 1 Day?
We use a single service class with explicit error handling. Example for Laravel:
class SmsRuService { public function send(string $phone, string $message): bool { $phone = preg_replace('/[^0-9]/', '', $phone); if (str_starts_with($phone, '8')) { $phone = '7' . substr($phone, 1); } $response = Http::get('https://sms.ru/sms/send', [ 'api_id' => config('services.smsru.api_key'), 'to' => $phone, 'msg' => $message, 'json' => 1 ]); return $response->json("sms.{$phone}.status") === 'OK'; } public function getBalance(): float { return Http::get('https://sms.ru/my/balance', [ 'api_id' => config('services.smsru.api_key'), 'json' => 1 ])->json('balance'); } } The class normalizes the number (8 → 7), sends the request, and checks the status. For asynchronous sending, we wrap the call in Laravel Queue or Redis Pub/Sub. The documentation for SMS.ru recommends using JSON response format for quick validation. Thanks to the provider contract, switching services (e.g., to SMSC.RU) is as simple as replacing one class.
Synchronous vs Asynchronous Sending
| Parameter | Synchronous Call | Asynchronous (Queue) |
|---|---|---|
| User delay | Yes (waits for response) | No (instant response) |
| Reliability | Lower (API failure breaks request) | Higher (retries on error) |
| Speed | ~500ms per SMS | ~10ms to queue job |
For high-load projects, asynchronous sending is mandatory—it is 2x faster for the user compared to synchronous.
Example queue setup in Laravel
class SendSmsJob implements ShouldQueue { use Dispatchable, InteractsWithQueue, Queueable, SerializesModels; public function handle(SmsRuService $service) { $service->send($this->phone, $this->message); } } Why Is Asynchronous Sending Critical?
With synchronous calls, each API request adds ~500ms to the server response time. If you have 1000 registrations per hour, that's 8 minutes of CPU time just waiting for SMS. Queues solve this: we enqueue a job in 10ms, and a background worker processes them in batches. Plus, retries on temporary API errors—synchronous code would simply fail, asynchronous will retry.
Balance Monitoring and Alerts
Zero balance means messages don't go out, and users don't receive OTPs. We set up a check every hour with notification via Telegram. The threshold is 100 RUB. Example code for a console command:
$balance = app(SmsRuService::class)->getBalance(); if ($balance < 100) { Notification::route('telegram', config('services.telegram.chat_id')) ->notify(new BalanceLowNotification($balance)); } Additionally, we log all API responses for quick diagnostics. If the balance is zero, sending doesn't happen—this directly impacts conversion. We also add overspend protection: a daily sending limit in code. Savings from timely top-ups can be up to 25,000 RUB per month by preventing downtime.
What to Do If SMS Are Not Delivered?
Check four points:
- Balance—most common cause.
- Number format: 7XXXXXXXXXX (no 8 or +).
- Sender name—must be registered with SMS.ru.
- API response status: code
100means success, others indicate errors.
We log all requests with response codes so you can spot a problem in a minute. One-time password (OTP) is the standard for verification, but without reliable delivery it's useless.
Scope of Work
- Code: service class with error handling, number normalization, and queue support.
- Tests: unit tests for SmsRuService and functional tests for sending scenarios.
- Monitoring: script to check balance with Telegram or Slack notifications.
- Documentation: description of configuration, environment variables, and integration points.
- Training: one-hour demonstration for your team.
- Support: two weeks after deployment to fix any issues.
Process and Timeline
- Analysis — review existing code, choose integration points (1-2 hours).
- Design — create service contract, provider factory.
- Implementation — write wrapper class, tests (Unit + Feature) — 4-6 hours.
- Testing — verify in SMS.ru sandbox (valid key + test number) — 2-4 hours.
- Deployment — roll out to staging, monitor logs — 1-2 hours.
| Stage | Duration | Result |
|---|---|---|
| Analysis | 1-2 hours | Architecture document |
| Implementation | 4-6 hours | Code + migrations |
| Testing | 2-4 hours | 20+ test cases |
| Deployment + training | 1-2 hours | Checklist, alerts |
