Telnyx Texml - 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

• **Pagination:** List endpoints return paginated results. Use `page[number]` and `page[size]` query parameters to navigate pages. Check `meta.total_pages` in the response.

Fetch multiple call resources

Returns multiple call resources for an account. This endpoint is eventually consistent.

`GET /texml/Accounts/{account_sid}/Calls`

curl -H "Authorization: Bearer $TELNYX_API_KEY" "https://api.telnyx.com/v2/texml/Accounts/{account_sid}/Calls?Page=1&PageSize=10&To=+1312345678&From=+1312345678&Status=no-answer&StartTime=2023-05-22&StartTime>=2023-05-22&StartTime<=2023-05-22&EndTime=2023-05-22&EndTime>=2023-05-22&EndTime<=2023-05-22"

Returns: `calls` (array[object]), `end` (integer), `first_page_uri` (string), `next_page_uri` (string), `page` (integer), `page_size` (integer), `start` (integer), `uri` (string)

Initiate an outbound call

Initiate an outbound TeXML call. Telnyx will request TeXML from the XML Request URL configured for the connection in the Mission Control Portal.

`POST /texml/Accounts/{account_sid}/Calls` — Required: `Url`

Optional: `Texml` (object)

curl \
  -X POST \
  -H "Authorization: Bearer $TELNYX_API_KEY" \
  -H "Content-Type: application/json" \
  "https://api.telnyx.com/v2/texml/Accounts/{account_sid}/Calls"

Returns: `from` (string), `status` (string), `to` (string)

Fetch a call

Returns an individual call identified by its CallSid. This endpoint is eventually consistent.

`GET /texml/Accounts/{account_sid}/Calls/{call_sid}`

curl -H "Authorization: Bearer $TELNYX_API_KEY" "https://api.telnyx.com/v2/texml/Accounts/{account_sid}/Calls/{call_sid}"

Returns: `account_sid` (string), `answered_by` (enum: human, machine, not_sure), `caller_name` (string), `date_created` (string), `date_updated` (string), `direction` (enum: inbound, outbound), `duration` (string), `end_time` (string), `from` (string), `from_formatted` (string), `price` (string), `price_unit` (string), `sid` (string), `start_time` (string), `status` (enum: ringing, in-progress, canceled, completed, failed, busy, no-answer), `to` (string), `to_formatted` (string), `uri` (string)

Update call

Update TeXML call. Please note that the keys present in the payload MUST BE formatted in CamelCase as specified in the example.

`POST /texml/Accounts/{account_sid}/Calls/{call_sid}`

Fetch recordings for a call

Returns recordings for a call identified by call_sid.

`GET /texml/Accounts/{account_sid}/Calls/{call_sid}/Recordings.json`

curl -H "Authorization: Bearer $TELNYX_API_KEY" "https://api.telnyx.com/v2/texml/Accounts/{account_sid}/Calls/{call_sid}/Recordings.json"
