Bitrix24 Cloud and Self-Hosted

Bitrix24 operates as both a cloud service and as self-hosted installations on a client's server. This section helps prepare a REST application to work with the self-hosted version: accounting for the differences of the self-hosted version, opening the necessary network access on the client side, and complying with security requirements.

If you are just starting, open REST API Peculiarities in the Self-Hosted Version — it covers the main differences between the self-hosted version and the cloud. Network access and security will be required during the implementation stage at the client site.
