I need to know that which all companies are using JIRA rest api to create an issue and if they are using then which authentication are they using OAuth authentication or Basic Authentication

Hi! Welcome to the Atlassian Community.

Impossible to say how many companies are creating issues via Jira's REST API but it is certainly something that is being used by a lot of companies. Often in integrations with other applications or monitoring systems where those systems create tickets in Jira.

Personally I have only seen basic authentication with an API token in Jira Cloud.

May we know what your use-case is?

[Shlok Ulva]

Which is the best way to authenticate to JIRA rest Api, OAuth authentication or Basic Authentication ? and generally companies prefer which authentication?

[Charlie Misonne]

For simple scripts where you use a utility like curl basic auth would be the only way to authenticate.

See Security overview 

Scripts and other REST API clients use basic authentication.

If you develop an app yourself you can use OAuth.

My use case is that I need to create a ticket in JIRA using REST API if my tool receives any configured alerts so which authentication mechanism shall I prefer (OAuth or Basic)? and in your experience what authentication mechanism (basic or OAuth) are similar organizations using to address this use case ?

If you can name some similar organizations ? and auth mechanism they are using ?

I would focus on OAuth2 if you are writing a new application for customers considering Basic Authentication will become deprecated over time.
