Create issue with REST API via oAuth2

Jens_7pl4p5

Hi, 

we are aggregating and analysing server logs with graylog. Now we like to create jira issues for certain events. 

We like to solve this using oAuth2 access via the developer console following this instructions: https://support.atlassian.com/jira/kb/how-to-use-oauth20-in-postman-client-for-jira-cloud-apis/

Authorisation already works

But i have trouble putting the request URL together. In step 3 the documentation tells me to use a site id for the xxx in the request URL. I don't know what the site id is. I tried than using the app id from the oauth app i created in the developer console. This didn't work.

My Request Example: 

I substituted the xxx with the app id, as i dont know yet what a site id is. 

curl --location 'https://api.atlassian.com/ex/jira/xxxxxxxx-xxxx-xxxx-xxxxxxxxxxxx/rest/api/2/project' \
--header 'Accept: application/json' \
--header 'Authorization: ••••••'

The response

Hello @Jens, It's important to mention that the site ID (also known as cloud ID or Tenant ID) is a unique identifier for your Jira cloud instance. It is not the same as the app ID you created in the developer console. You can find your cloud ID from the admin console following the steps on this page here.
