Clarification on Technical Requirements for AppSource Publishing

(2) ShareShare

Posted on by 2,116

Hello Community,

We are in the process of creating an add-on for Business Central and are following the steps outlined in Microsoft's Technical Validation documentation. Since this is our first time publishing to AppSource, we would like some clarification on a few points:

  1. We have registered our publisher prefix (Affix) with Microsoft for AppSource.
  2. When we try to register for the object range, we are required to log in to the Microsoft Partner Center account. However, when we attempt to log in, we receive an error. Do we need a different type of partner account subscription, such as an active support plan or active partner entitlements, to access this?
  3. Is a Code Signing Certificate mandatory for submitting an app to AppSource?
  4. Is it mandatory to sign the app package (.app file) using a .pfx certificate before submission?
  5. We have not yet set up automated testing for our extension. Is it required for the AppSource submission process?

Could someone please confirm which of the above steps are mandatory and which tools or services we need to purchase or set up in order to successfully upload our extension to AppSource?

Thank you in advance for your guidance!
