Telnyx Storage - 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).

Get API Usage

Returns the detail on API usage on a bucket of a particular time period, group by method category.

GET /storage/buckets/{bucketName}/usage/api

curl -H "Authorization: Bearer $TELNYX_API_KEY" "https://api.telnyx.com/v2/storage/buckets/{bucketName}/usage/api?filter={'start_time': '2020-01-01T00:00:00.000Z', 'end_time': '2020-01-01T00:00:00.000Z'}"

Returns: categories (array[object]), timestamp (date-time), total (object)

Get Bucket Usage

Returns the amount of storage space and number of files a bucket takes up.

Create Presigned Object URL

Returns a timed and authenticated URL to download (GET) or upload (PUT) an object. This is the equivalent to AWS S3’s “presigned” URL. Please note that Telnyx performs authentication differently from AWS S3 and you MUST NOT use the presign method of AWS s3api CLI or SDK to generate the presigned URL.

POST /storage/buckets/{bucketName}/{objectName}/presigned_url

Optional: ttl (integer)

curl \
  -X POST \
  -H "Authorization: Bearer $TELNYX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "ttl": 60
}' \
  "https://api.telnyx.com/v2/storage/buckets/{bucketName}/{objectName}/presigned_url"
