Bitrix24. Market contains a lot of useful applications that help expand the functionality of the basic product: connect additional payment methods, PBXs, or chatbots.
Despite the fact that these solutions integrate perfectly and may seem as if they are a part of Bitrix24, these apps are released by third-party developers, who can consult you about their apps.
How to find developer contacts
Open the Market page and search for the desired application in the search bar or in the categories.
Open the application form, and then the Support tab. There you will find all the developer's contacts.
