# Telnyx Texml - curl

## Installation

```text
# curl is pre-installed on macOS, Linux, and Windows 10+
```

## Setup

```bash
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:

```bash
# 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`

```bash
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: `call_sid` (string), `from` (string), `status` (string), `to` (string)

## Create a connection-scoped TeXML call

Initiate an outbound TeXML call using a TeXML application connection ID, not an account SID. Request parameter names are case-sensitive. From and To are required; Texml supplies inline instructions and Url overrides the application XML request URL. When neither is supplied, the application configuration supplies the instructions. The response is a flat call object without a data wrapper.

`POST /texml/calls/{connection_id}` — Required: `From`, `To`

Optional: `Method` (enum: GET, POST), `Texml` (string), `Url` (string)

```bash
curl \
  -X POST \
  -H "Authorization: Bearer $TELNYX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "From": "+13120001234",
  "To": "+13121230000",
  "Texml": "<Response><Say>Hello</Say></Response>"
}' \
  "https://api.telnyx.com/v2/texml/calls/1234567890"
```

Returns: `call_sid` (string), `from` (string), `status` (enum: queued), `to` (string)

## Create a TeXML secret

Create a TeXML secret which can be later used as a Dynamic Parameter for TeXML when using Mustache Templates in your TeXML. In your TeXML you will be able to use your secret name, and this name will be replaced by the actual secret value when processing the TeXML on Telnyx side. The secrets are not visible in any logs.

`POST /texml/secrets` — Required: `name`, `value`

```bash
curl \
  -X POST \
  -H "Authorization: Bearer $TELNYX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "name": "My Secret Name",
  "value": "My Secret Value"
}' \
  "https://api.telnyx.com/v2/texml/secrets"
```

Returns: `name` (string), `value` (enum: REDACTED)
