Telnyx Oauth - 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.

Authorization server metadata

OAuth 2.0 Authorization Server Metadata (RFC 8414)

`GET /.well-known/oauth-authorization-server`

Protected resource metadata

OAuth 2.0 Protected Resource Metadata for resource discovery

`GET /.well-known/oauth-protected-resource`

curl -H "Authorization: Bearer $TELNYX_API_KEY" "https://api.telnyx.com/v2/.well-known/oauth-protected-resource"

Returns: `authorization_servers` (array[string]), `resource` (uri)

OAuth authorization endpoint

OAuth 2.0 authorization endpoint for the authorization code flow

`GET /oauth/authorize`

curl -H "Authorization: Bearer $TELNYX_API_KEY" "https://api.telnyx.com/v2/oauth/authorize?scope=admin"

List OAuth clients

Retrieve a paginated list of OAuth clients for the authenticated user

`GET /oauth/clients`

  -H "Content-Type: application/json" \
  -d '{
  "name": "My OAuth client",
  "allowed_scopes": [
    "admin"
  ],

Get OAuth client

Returns the details of a single OAuth client on your account by its ID.

`GET /oauth/clients/{id}`

curl -H "Authorization: Bearer $TELNYX_API_KEY" "https://api.telnyx.com/v2/oauth/clients/550e8400-e29b-41d4-a716-446655440000"
