-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" ;;
esacCommon 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).
