To purchase numbers via API, refer to our documentation, which provides a detailed
explanation of the integration process and required requests: https://smsfast.com/doc
The API is a protocol for interaction between your software and our activation service. It is necessary to automate the SMS receiving process on your side.
Our API provides developers with a powerful tool for deep integration of the temporary number rental service into any business processes or applications. It allows you to fully automate operations with numbers, minimizing manual actions and ensuring the scalability of solutions.
Through the API, you can programmatically manage all key functions: from renting a number to receiving incoming messages. The system supports the creation of numbers in activation mode (for one-time verifications) and long-term rental (with the possibility of extension). When requesting a number, you specify the target service (Telegram, WhatsApp, etc.), and you can also choose the country, operator, or rental period you are interested in (if you use rental numbers).
You can also use the API to quickly track all kinds of information. For example, you can find out the available prices and the number of numbers, or the amount of funds in your balance. The API also provides the ability to extend rental numbers.
Our documentation includes ready-made solutions for Python, PHP, and Java, which speeds up integration. You will get not just access to numbers, but a comprehensive solution for end-to-end automation of SMS verification processes. This allows you to significantly reduce time when working with mass registrations or account management.
