API Token: You need to create and provide the API token which corresponds to the source product. You’ll find specific instructions in the datasource creation screen.
User+password: you provide a user and password so Dashboard Hub will use it for data accessing. This user+password could be your user and password or another specific one to allow the data access.
Personal access token: the service allows you to create an extra pass to connect for data. You will generate this pass setting different permissions to the data access (like read-only access).
App password: the service allows you to create a special password key to connect for data (the user will not be required). You will generate this password setting different permissions to the data access (like read-only access).
Hybrid datasources: Server/Data Center supported versions
If you don’t know yet what is a Hybrid Dashboards and why do you need hybrid connectors, have a look to https://roninpixels.atlassian.net/wiki/spaces/RDD/pages/301203814. But in summary, you can connect to a server or data center instance from your cloud dashboard. For doing so, create a new Jira server/data center or Confluence server/data center datasource and use it like any other datasource.
