How is information protection carried out when interacting with third-party services?

Information security when interacting with third-party services is achieved through several key mechanisms:

• Data encryption — transmitting data over secure protocols (e.g., HTTPS with TLS) to prevent interception and reading by third parties.
• Authentication and authorization — using API keys, tokens (OAuth, JWT), or certificates to verify the client's identity and restrict access.
• Data validation and filtering — checking incoming and outgoing data to prevent injections and other attacks.
• Logging and monitoring — tracking requests and responses to identify suspicious activity.
• Isolation and access restrictions — minimizing access rights for services and users to limit potential damage in case of a breach.

For example, when calling a third-party REST API, HTTPS is usually used, and an authorization token is sent in the headers. This ensures that data is transmitted securely, and the service accepts requests only from authorized clients.
