Telnyx Verify - curl
Installation
# curl is pre-installed on macOS, Linux, and Windows 10+
Setup
export TELNYX_API_KEY="YOUR_API_KEY_HERE"
All examples below use $TELNYX_API_KEY for authentication.
Error Handling
All API calls can fail with network errors, rate limits (429), validation errors (422), or authentication errors (401). Always handle errors in production code:
# Check HTTP status code in response
response=$(curl -s -w "\n%{http_code}" \
-X POST "https://api.telnyx.com/v2/messages" \
-H "Authorization: Bearer $TELNYX_API_KEY" \
-H "Content-Type: application/json" \
-d '{"to": "+13125550001", "from": "+13125550002", "text": "Hello"}')
http_code=$(echo "$response" | tail -1)
body=$(echo "$response" | sed '$d')
case $http_code in
2*) echo "Success: $body" ;;
422) echo "Validation error — check required fields and formats" ;;
429) echo "Rate limited — retry after delay"; sleep 1 ;;
401) echo "Authentication failed — check TELNYX_API_KEY" ;;
*) echo "Error $http_code: $body" ;;
esac
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: List endpoints return paginated results. Use
page[number]andpage[size]query parameters to navigate pages. Checkmeta.total_pagesin the response.
