# OTPValidation Incubating API Repository to evolve and maintain the definitions and documentation of OTPValidation Service API within the Sub Project [Number Insights](https://lf-camaraproject.atlassian.net/wiki/x/BYEpBQ) * API Repository [wiki page](https://lf-camaraproject.atlassian.net/wiki/x/yDXe) ## Scope * Service APIs for “OTPValidation” (see APIBacklog.md) * The OTP SMS API facilitates real-time verification of a user's device by sending a unique code via SMS to the specified mobile phone number. The process involves three key steps: 1. **Code Generation and Delivery:** The send-code operation is used by the API consumer (e.g., an application) to request a one-time code to be sent by SMS to the application user's mobile phone along with an message to the user's mobile device. 2. **User Input:** The user receives the SMS and enters the received code into the application. 3. **Verification:** The application submits the entered code using the validate-code operation, which then verifies its accuracy and responds with a confirmation indicating whether the code is valid. This process ensures secure, real-time validation of user possession of the specified device, enhancing authentication security. * by delivering a one-time password (OTP) to it through SMS and validating the received code with the user's operator after the code is entered as requested. * Started: October 2022 * Incubating stage since: February 2025 ## Release Information > [!NOTE] > Please be aware that the project will have frequent updates to the main branch. There are no compatibility guarantees associated with code in any branch, including main, until a new release is created. For example, changes may be reverted before a release is created. **For best results, use the latest available release**. * **NEW**: The latest public release is [r3.2](https://github.com/camaraproject/OTPValidation/releases/tag/r3.2) (Fall25), with the following API versions: * **one-time-password-sms v1.1.1** [[YAML]](https://github.com/camaraproject/OTPValidation/blob/r3.2/code/API_definitions/one-time-password-sms.yaml) [[ReDoc]](https://redocly.github.io/redoc/?url=https://raw.githubusercontent.com/camaraproject/OTPValidation/r3.2/code/API_definitions/one-time-password-sms.yaml&nocors) [[Swagger]](https://camaraproject.github.io/swagger-ui/?url=https://raw.githubusercontent.com/camaraproject/OTPValidation/r3.2/code/API_definitions/one-time-password-sms.yaml) * The latest public release is always available here: https://github.com/camaraproject/OTPValidation/releases/latest * Other releases of this repository are available in https://github.com/camaraproject/OTPValidation/releases * For changes see [CHANGELOG.md](https://github.com/camaraproject/OTPValidation/blob/main/CHANGELOG.md) _The above section is automatically synchronized by CAMARA project-administration._ ## Contributing * Meetings are held virtually * Schedule: Every 4 weeks, Thursday, 7:30 AM UTC (8:30 CET/9:30 CEST) * [Registration / Join](https://zoom-lfx.platform.linuxfoundation.org/meeting/94893248838?password=05b2197d-309e-41ef-aadf-639f71ef7f38) * Minutes: Access [meeting minutes](https://lf-camaraproject.atlassian.net/wiki/spaces/CAM/pages/14564484/Minutes+-+Number+Insights) * Mailing list * Subscribe / Unsubscribe to the mailing list . * A message to the community of this Sub Project can be sent using .
