All examples below assume client is already initialized as shown above.
All API calls can fail with network errors, rate limits (429), validation errors (422), or authentication errors (401). Always handle errors in production code:
import com.telnyx.sdk.errors.TelnyxServiceException;
try {
var result = client.messages().send(params);
} catch (TelnyxServiceException e) {
System.err.println("API error " + e.statusCode() + ": " + e.getMessage());
if (e.statusCode() == 422) {
System.err.println("Validation error — check required fields and formats");
} else if (e.statusCode() == 429) {
// Rate limited — wait and retry with exponential backoff
Thread.sleep(1000);
}
}
Common error codes: 401 invalid API key, 403 insufficient permissions,
404 resource not found, 422 validation error (check field formats),
429 rate limited (retry with exponential backoff).
