We have completely reorganized and re-written the Apps&partners section of the developer community. And we will be adding more content, so stay tuned!
You can find the new landing-page at https://community.superoffice.com/en/developer/create-apps/.
Expect hard-coded links from forum posts to sub-pages of developer/apps-partners/ to break. Be pleasantly surprised if they work..
The easiest way to locate the linked content is to use our internal search. Let us know if you have trouble finding something :)
