Web API
SonarCloud provides a web API to access its functionalities from applications. The web services composing the web API are documented within SonarCloud, through the URL https://sonarcloud.io/web_api. You can also access the web API documentation from the top bar in Cloud by selecting the help button:

User tokens can be used to perform analyses or invoke web services. You can pass the token instead of your usual login. The token is sent via the login field of HTTP authentication, without any password.
For detailed information on user tokens and authentication, see User accounts.
API rate limiting
Some of SonarCloud's APIs are rate-limited in order to ensure that we can continue to deliver the service smoothly and with optimum performance. In most cases, you should take this into account when automating tasks and processes by using the SonarCloud Web API.
Your API calls will fail with a 429 status code when the rate limit has been reached. If this happens, wait a few minutes before retrying the operation.
