What role in Jira do I need to create a new project, task, subtask, bug by using jira java api ?

I'm trying to create new task in jira using java. My api call is returning 201 response, but when I'm checking in jira dashboard those task are not available there which I'm creating from my code.

@biswaranjanrout.amai @M Amine is correct about permissions. Few small points I would like to add,

• As your API is returning 201, can you check it's JSON response, if issue is created in Jira you will get id and key of issue in JSON response.

• To create a project you have to be Jira Admin. 
• To create an issue in a project you have to have the "Browse Project" + "Create issue" Permissions in the Project Permission Scheme

Those rules stay the same for API Call.
