Would Microsoft Teams SDK for Python (Preview) affect marketplace submission

Hi,

I need to know if it's possible to publish a custom teams app and get validated to have the app in marketplace for public if it's developed using Teams SDK with python which is mentioned as still in preview.

 

Teams SDK is now generally available for JavaScript and C#, supports Python in developer preview

Thank you!

    You can publish a Teams app built with the Python SDK, but because Python support is still in developer preview, apps using it are not eligible for full marketplace validation and public listing. Only apps built with the generally available SDKs (JavaScript and C#) can currently pass Microsoft’s marketplace certification process.

    Hey tharushikds​ ,

    Thanks for reaching out — great to hear you're building with our SDK!

    You're right that we're still in public preview for Python. We've been working hard to maintain compatibility, but there are some breaking changes coming before our official GA release. Because of this, we'd recommend holding off publishing until then to avoid potential disruption.

    That said, we'd love to support you along the way. Could you share more about your use case and how you're using the library? We'd be happy to help!
