The task of integrating the CRM Bitrix24 with WhatsApp was implemented by me and my team 4 times using various methods. (2 times for Cloud Bitrix24 and 2 times for Self-hosted Bitrix24). We have been working on this task for the last 3 months. The WhatsApp messenger has not yet opened API for everyone, so in order to integrate Bitrix24 with WhatsApp, we had to use third-party services as a proxy.
AWS, Python, Dynamo DB, MongoDB, Serverless, NoSQL, AWS Lambda, Bitrix24, PHP, SQL, MySQL
