Push API

To use Push API you need to have individual User API token, which can be found in the settings of space.

You’ll see the block with User API token on the space settings page only in case if your tariff plan and access rights allow to use devtodev API. You can reset User API token or create it again on the same page.

Please attend, if you use several spaces, in every space user has individual User API token.
