What considerations should I keep in mind when handling exceptions related to external APIs?

When dealing with external API calls, handle exceptions like `HttpRequestException`, `TimeoutException`, and API-specific exceptions. Implement retry logic with exponential backoff for transient errors. Log the API request and response details for debugging. Consider circuit breaker patterns to prevent cascading failures if the external API is unavailable. Return informative error messages to the user without exposing sensitive API details.
