How to get the JIRA data to Power BI? i mean without using the AIO Connector?
I am the only developer uses AOI connector so it doesn't make sense to but license for all JIRA users with this connector license.
So, need help to get data from JIRA to power BI.
You can use PowerBI's built-in connector for free here - https://powerbi.microsoft.com/en-us/blog/explore-your-jira-data-with-power-bi/
This is largely a config activity, similar to the AIO connector, to ensure the connector integrates with your instance properly, and may require some data manipulation in the PowerBI program to create a truly 'clean' data source.
Utilising the JIRA API, whilst more powerful than an out-of-the-box solution, can be much more difficult to get of the ground as you're essentially building a script that can authenticate with your Jira instance, collect & prepare the data, store it in an accessible location (usually as a .json, .xml or .csv file), and have that script run on a batch job to update at a suitable frequency (daily, weekly, monthly etc.).
Link to the Cloud API - https://developer.atlassian.com/cloud/jira/platform/rest/v3/intro/
Link to the Server API - https://docs.atlassian.com/software/jira/docs/api/REST/latest/
These two APIs are largely similar with regards to their end points, the only key difference being authentication methods can vary between the two.
Hope that helps!
