Automating account creation workflows or scaling a SaaS platform requires a reliable method to handle mandatory mobile authentication. Manual number acquisition stalls development pipelines and breaks automated testing suites. NumbersStore provides an advanced SMS API for developers, backend engineers, and automation specialists. This phone number API allows technical teams to programmatically request real, non-VoIP numbers and receive authentication codes directly within their applications. Integrating our SMS verification API eliminates manual bottlenecks, enabling continuous deployment, robust automated testing, and seamless user onboarding workflows at scale.
What Makes Our API Advanced?
Our architecture relies on standard RESTful principles, providing a robust REST API SMS solution with predictable URLs and standard HTTP response codes. Unlike legacy systems that force constant endpoint polling, we utilize real-time Webhooks. This event-driven approach pushes the text payload to your server immediately. Responses use clean JSON for straightforward parsing. We provide comprehensive multi-language support, offering code snippets for cURL, Python, Node.js, PHP, and Ruby. Furthermore, API access scales intelligently, applying structured rate limits based on your subscription plan to maintain high uptime (99.98%) across our entire network.
Core API Capabilities
Developers can script complete verification lifecycles programmatically using these core endpoints:
- Get Balance: Check current available funds before executing requests.
- Get Services & Prices: Retrieve the live catalog of supported services and current market rates.
- Buy Number: Request a fresh, non-VoIP number for a specific target platform.
- Order Status: Retrieve the incoming verification code payload securely.
- Cancel Number: Abort a pending request and trigger an automatic refund.
- Reactivate Number: Request a secondary code for the exact same service.
- Rental Services: Provision and manage long-term rental lines autonomously.
- Webhook Configuration: Dynamically set or update your destination URL endpoints.
Webhook Integration
Modern automation demands efficiency, which is why our Webhook integration replaces outdated polling methods. When a platform sends a code, our servers push webhook SMS notifications directly to your endpoint in under 15 seconds. The JSON payload structure delivers precise data, including the full text message and timestamps. To ensure data integrity, we enforce strict security protocols requiring HTTPS endpoints and authentication tokens. If your server experiences downtime, our robust retry mechanism attempts delivery multiple times over a five-minute window, ensuring no authentication codes are ever lost.
Rate Limits & Pricing
To guarantee network stability, API requests are governed by tier-based rate limits. The Basic tier allows 10 requests per minute, suitable for testing. Plus increases to 30 requests per minute. High-volume users require the Pro tier at 60 requests per minute, while enterprise operations utilize the Max tier, supporting 90 requests per minute. Review token costs on our pricing page.
Frequently Asked Questions
Where can I find the official API documentation?
Developers can access comprehensive guides, endpoint definitions, and specific code examples for Python, Node.js, and PHP within our official API documentation. We regularly update these technical resources to reflect new endpoint parameters, payload structures, and best practices for verification API integration.
What happens if an API call fails to retrieve an SMS?
Our API follows the exact same Pay-on-Success model as the web dashboard. If you initiate a number purchase and the target platform fails to send the text message before the timeout period, invoking the cancellation endpoint guarantees an automatic refund to your balance.
Do you offer technical support for API integration issues?
Yes, we provide dedicated assistance for backend engineers and automation specialists. If you encounter persistent HTTP 400 errors or webhook delivery failures, you can contact our technical support team for direct troubleshooting. Our specialists review server logs to pinpoint integration bottlenecks quickly.
