How can I get project name?

Answer 1

You won't have it through a JSON payload send by a (GitLab) webhook, since GitLab knows nothing about Sonar (natively).

You need to deduce the Sonar project name from the files of the project themselves.

Typically (for instance) a Maven project would use the pom.xml project name as its Sonar project name: see "Is it possible to tell Sonar the project name from the command line?".
