I have 2 extensions developed for Magento 1/2 respectively which pass the validation tool which magento provides.
What's the process for Magento to approve the extensions for marketplace usage in both 1 / 2.
These apps are free and are used to communicate to an external API.
Thanks in advance.
Maybe you can check here to know a little but more about the whole process:
