Answer from AI

The method getExternalOrderIdFromCRM is responsible for retrieving data from an external system (CRM), so it belongs to the layer of integration with external services.

It is recommended:

To allocate a package or module in the project responsible for working with CRM, for example crm or external.
To place the getExternalOrderIdFromCRM function in this package, which encapsulates the logic of contacting the CRM (HTTP requests, response processing).
To call this method from business logic through an interface or service to separate integration details from the core logic.

Example structure:

/project
  /crm
    crm.go       // contains getExternalOrderIdFromCRM
  /service
    order.go     // uses crm.getExternalOrderIdFromCRM
  main.go

This approach improves readability, testability, and maintainability of the code.
