We've developed an add-in and are looking at how to publish it on the ArcGIS Marketplace. The steps look straightforward until the "register an app" part (Register an app—ArcGIS Marketplace Help | ArcGIS); there's no clear set of instructions for add-ins afterwards. Any code or configuration changes we need to apply to the add-in? How does the OAuth 2.0 requirement apply to add-ins? Any help would be appreciated.
Hello Mark, great to hear you have a Pro add-in ready for the Marketplace. This Marketplace blog post should help you with the steps for creating your listing for your add-in. There are no additional code or configuration changes you need to to make to your add-in for the listing, and also the OAuth 2.0 points are not applicable for Pro add-in listings.
