Amocrm link to api site

Site on php Yii2 mysql.
It is necessary to transfer information from the user profile to amocrm through the amocrm api.
1. Create a contact, company and transaction immediately after the user places the service on our website.
2. Bind and record the id of companies from amocrm in the appropriate field of the company in our DB.
2. Update the information in the fields after they are changed on our website.
3. Reverse synchronization is not yet planned.
4. In the admin of the site you need to withdraw the logging of data transfer processes and company id from amocrm

In total, we will transfer/update about 20 fields.
