Announcing General Availability of Custom and Certified Connectors for Power BI

Headshot of article author Colin Popell

We are happy to announce that Custom and Certified Connectors in Power BI are now generally available!

Custom and Certified Connectors

After delivering the Power BI Custom Connectors SDK, our incredible community has developed hundreds of connectors. Some of these were developed by vendors, some by consultants, and some by third parties who were passionate enough about Power BI to write connectors for specific data sources. It’s been an incredible success, and we’re happy to announce it is no longer a preview feature!

Custom Connectors for Power BI are modules that extend Power BI’s capabilities to connect to data sources not covered by what’s shipped with the product. We’ve seen these used to connect to databases, web services, and even specific private data sets (such as census data).

As this feature is no longer in preview, connectors are now fully supported in Power BI Desktop, the On Premise Data Gateway (Personal and Enterprise), and Power BI Service (via the Gateway). We support both refresh of data through import as well as direct query for those connectors that support it. We also have now have a dedicated Power Query section on Microsoft Docs, with all the information you might need to develop a Custom Connector, alongside our existing M Language Reference.

Alongside this, we are announcing our ‘Certified Connector’ program. A certified connector is:

  • Built by the developer
  • Evaluated by Microsoft
  • Distributed by Microsoft
  • Maintained by the developer
  • Supported by the developer

This program will allow owners of data sources to deliver connectors seamlessly via Get Data in Power BI, making it easy for you to take advantage of the capabilities of Power BI and the breadth of our audience.

Connector support is provided by the connector owner, with assistance to the connector owner from Microsoft. If you’re a vendor interested in certifying your connector, reach out to us via this form. More information about requirements can be found here.

We encourage the community to use custom connectors to enable bringing all their data into Power BI, not just from sources we already support. Many vendors have reached out to work with us already, and more information about some of the connectors we’ve already certified are below.

What does this mean?

Custom Connectors are now Generally Available and every Power BI user is encouraged to leverage them – whether that is building new connectors or leveraging connectors built by others. This includes Certified connectors that are distributed seamlessly, as well as using other Custom Connectors built by 3rd parties.

We have new security settings under ‘Security’ in ‘Options’. If you’d like to know more about the security levels, please read the documentation page here. You’ll note that there are two security levels currently—one for ‘custom connectors’ and one for ‘certified connectors’. Because we go through all certified connectors to make sure they’re safe, we’re willing to distribute them at the higher level of security.

However, to ensure your security, modules not certified by Microsoft will not load without changing security settings.

We are aware that there are lots of connectors don’t fall into the certified path, as mentioned above. Sometimes, however, you may trust a vendor to provide you a connector that (for whatever reason) isn’t easily certifiable. It could be a data back-end they don’t own, it might be a specific data set, or it might be a private database technology not generally available on the market. There are lots of reasons, and we will do our best to support this use-case.

Certified Connectors in October Release

As mentioned above, we’ve worked with a number of vendors already on the Certified Connector program. Below is a blurb about each of them. Some of these connectors (Exasol, JethroData, and TeamDesk) were introduced under the feature switch a few months ago—check them out! The others are brand new with the October release of Power BI. All statements below, aside from learn more links, are taken from the ISV.
