pip install telnyx
import os
from telnyx import Telnyx
client = Telnyx(
api_key=os.environ.get("TELNYX_API_KEY"), # This is the default and can be omitted
public_key=os.environ.get("TELNYX_PUBLIC_KEY"), # Required for client.webhooks.unwrap() (webhook verification)
)
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 telnyx
try:
result = client.messages.send(to="+13125550001", from_="+13125550002", text="Hello")
except telnyx.APIConnectionError:
print("Network error — check connectivity and retry")
raise
except telnyx.RateLimitError:
# 429: rate limited — wait, then retry the request (bounded exponential backoff)
import time
time.sleep(1) # Check Retry-After header for actual delay
# ...retry the call here (give up after a few attempts); otherwise re-raise:
raise
except telnyx.APIStatusError as e:
print(f"API error {e.status_code}: {e.message}")
if e.status_code == 422:
print("Validation error — check required fields and formats")
raise # A failed request must never look like success to the caller
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).
