All examples below assume `client` is already initialized as shown above.
## Error Handling
All API calls can fail with network errors, rate limits (429), validation errors (422),
or authentication errors (401). Always handle errors in production code:
```go
import "errors"
assistant, err := client.AI.Assistants.New(context.Background(), telnyx.AIAssistantNewParams{
Instructions: "You are a helpful assistant.",
Name: "my-resource",
Model: "openai/gpt-4o",
})
if err != nil {
var apiErr *telnyx.Error
if errors.As(err, &apiErr) {
switch apiErr.StatusCode {
case 422:
fmt.Println("Validation error — check required fields and formats")
case 429:
fmt.Println("Rate limited, retrying...")
default:
fmt.Printf("API error %d: %s\n", apiErr.StatusCode, apiErr.Error())
}
} else {
fmt.Println("Network error — check connectivity and retry")
}
}
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).
Important Notes
- Phone numbers must be in E.164 format (e.g.,
+13125550001). Include the+prefix and country code. No spaces, dashes, or parentheses. - Pagination: Use
ListAutoPaging()for automatic iteration:iter := client.Resource.ListAutoPaging(ctx, params); for iter.Next() { item := iter.Current() }.
Reference Use Rules
Do not invent Telnyx parameters, enums, response fields, or webhook fields.
- If the parameter, enum, or response field you need is not shown inline in this skill, read references/api-details.md before writing code.
- Before using any operation in
## Additional Operations, read the optional-parameters section and the response-schemas section.
