Setup
import (
"context"
"fmt"
"os"
"github.com/team-telnyx/telnyx-go" "github.com/team-telnyx/telnyx-go/option" )
client := telnyx.NewClient( option.WithAPIKey(os.Getenv("TELNYX_API_KEY")), )
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"
result, err := client.Messages.Send(ctx, params)
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:
// Rate limited — wait and retry with exponential backoff
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
- Pagination: Use
ListAutoPaging()for automatic iteration:iter := client.Resource.ListAutoPaging(ctx, params); for iter.Next() { item := iter.Current() }.
