Support For Open API v3

Currently PowerApps supports creating services based on OpenAPI v2. When is the plan to support v3?

So odd this is not in the tooling.

What are we missing by not having support for OpenApi 3?

I think there are advantages of supporting OpenAPI 3 both in terms of improving developer efficiency and providing developers with more technical flexibility.

For our projects, advantages of OpenAPI 3 support would include:
- a large number of 3rd party cloud services publish their API definitions (via GitHub) as OpenAPI 3. These currently then need be converted back to Open API 2. This is often not just a once off translation but need to be repeatedly done as their APIs evolve. Whilst tools are available to assist with this, manual intervention or tweaks are often required.

- most other development aspects of our projects use OpenAPI v3. Developers often need to then "refresh" there memory of Open API 2 when creating/modifying custom connectors

- newer development tools are focused on OpenAPI 3 (and often have limited support for OpenAPI 2). These tools cannot be used when developing custom connectors that rely on OpenAPI 2

- we often find that OpenAPI 2 definitions are less intuitive and take longer to code than OpenAPI 3 definitions. A good example of this is the simplified document structure of OpenAPI 3 that moves "definitions", "securityDefinitions", "responses" and "parameters" to a consolidated "components" element. Another example is that the "body" and "formData" parameter types elements have been replaced with a "requestBody" element.

- base paths cannot be easily parameterised in OpenAPI 2. In OpenAPI 3, server variables can be used

It is worth noting that support for OpenAPI *3.1* (rather than 3.0) would be even more preferable. This would provide benefits such as:

- full compatibility with JSON Schema
- setting "type" as an array

- support for type "null"

- use of the examples keyword

There are probably many more benefits but these are the ones that would help us during day to day development on our projects.

Even the Official Microsoft Graph SDK uses Open API Specification v3.0.1.


I tried importing it as a Power Apps Connector... No luck! Tried converting it to Swagger 2.0 and then import, no luck! Tried converting it to Postman 1.0 (deprecated) and then importing it, no luck!


Please! When can we get OAS 3.0 support for Power Apps Connectors?

This is a pretty big miss.  In fact, PowerApps entire handling of web services is still lagging behind industry badly. Currently, integrating with custom connectors is a hack, at best.  Microsoft needs to upgrade web services to become a first citizen alongside the current data connectors because most of the world is going away from direct data access.


I think support for OpenAPI 3.0 should be considered a core capability for the Power suite and I suspect Microsoft is working on it.  Unfortunately, insufficient communications are a chronic issue for the PA team.  Can we at least get an acknowledgement that it is on the roadmap somewhere?  If not, the appearance to the community is that Microsoft is knowingly sticking with dated technology and all of the web service integration issues that come with it.

When is the planned role out for this this is something we need ASAP

I am surprised this is not available yet. This is a tool I need for where I work.  It would make it a lot easier.

Is there any update on this? You guys are very very late.
