Tell us about working with integrations, protocols. What REST API methods do you use and for what purpose?

When working with integrations, protocols like HTTP/HTTPS are often used because they are universal and supported by most systems. REST API is one of the most popular ways for services to interact.

Main methods of REST API:

• GET — to retrieve data from the server. For example, requesting a list of users.
• POST — to create new resources. For example, adding a new order.
• PUT — for full update of an existing resource.
• PATCH — for partial update of a resource.
• DELETE — to delete a resource.

The use of methods depends on business logic. For example, for CRM integration, GET can be used to retrieve client information, POST to create new records, PUT/PATCH to update data, and DELETE to remove outdated records.

It is also important to consider data formats (JSON, XML), authentication (OAuth, API keys), and error handling (HTTP status codes).
