During one of our recent implementations, CRM Bitrix24 was used as a backend for another external system - for a student's account. Through an account interface, students can apply for training in the chosen course, upload the necessary documents, monitor the status of their application, pay tuition bills, and also interact with their curators. All this is very deeply integrated with Bitrix24 business processes. For such a deep integration of Bitrix with a third-party system, we lacked standard REST methods - the logic for using requests became too complicated and confusing.

Many of my clients use Bitrix24 cloud version as a CRM system and project management system. The main advantage of the cloud version over the on-premise is that the client does not need to think about a server, it's support and security. However, this advantage is partially lost when the need arises to extend the functionality of Bitrix24 through custom applications. Fortunately for the operation of simple non-replicable applications, those for which webhooks are usually used, do not need a server. Serverless service Lambda from AWS (Amazon Web Services) https://aws.amazon.com/ru/lambda/ and Amazon API Gateway https://aws.amazon.com/ru/api-gateway/ are enough.
