Marketplace apps that are created on, or migrated to, the new HubSpot Developer Platform now have customer install limits.
Apps with the “marketplace” distribution type are limited to 25 customer installs until they are listed on the HubSpot Marketplace, and apps distributed privately using OAuth are limited to 10 customers (or up to 100 customers for Solution Partners).
App partners who plan to use new features on the updated HubSpot Developer Platform need to account for these limits when preparing their app and Marketplace listing.
All new apps created with the “marketplace” distribution type on the Developer Platform, or apps migrated as public apps from the previous platform, are limited to a maximum of 25 customer installs until they are listed on the HubSpot Marketplace.
Alternatively, partners can distribute their apps privately to customers using OAuth. Private distribution is limited to 10 customers, or up to 100 customers for Solution Partners. More information about managing the distribution configuration for your app is available here.
You can find details about the Marketplace listing process and requirements here.
This applies to all hubs and tiers.
