Telnyx Messaging Hosted - Python

Installation

pip install telnyx

Setup

import os
from telnyx import Telnyx

client = Telnyx(
    api_key=os.environ.get("TELNYX_API_KEY"),  # This is the default and can be omitted
    public_key=os.environ.get("TELNYX_PUBLIC_KEY"),  # Required for client.webhooks.unwrap() (webhook verification)
)

All examples below assume `client` is already initialized as shown above.

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:

import telnyx

try:
    result = client.messages.send(to="+13125550001", from_="+13125550002", text="Hello")
except telnyx.APIConnectionError:
    print("Network error — check connectivity and retry")
    raise
except telnyx.RateLimitError:
    # 429: rate limited — wait, then retry the request (bounded exponential backoff)
    import time
    time.sleep(1)  # Check Retry-After header for actual delay
    # ...retry the call here (give up after a few attempts); otherwise re-raise:
    raise
except telnyx.APIStatusError as e:
    print(f"API error {e.status_code}: {e.message}")
    if e.status_code == 422:
        print("Validation error — check required fields and formats")
    raise  # A failed request must never look like success to the caller

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

• **Phone numbers** must be in E.164 format (e.g., `+13125550001`). Include the `+` prefix and country code. No spaces, dashes, or parentheses.
• **Pagination:** List methods return an auto-paginating iterator. Use `for item in page_result:` to iterate through all pages automatically.

Send an RCS message

Queues an outbound RCS message through the selected RCS agent. Check recipient capabilities before sending features that require RCS support.

`POST /messages/rcs` — Required: `agent_id`, `to`, `messaging_profile_id`, `agent_message`

Optional: `mms_fallback` (object), `sms_fallback` (object), `type` (enum: RCS), `webhook_url` (url)

response = client.messages.rcs.send(
    agent_id="Agent007",
    agent_message={},
    messaging_profile_id="550e8400-e29b-41d4-a716-446655440000",
    to="+13125551234",
)
print(response.data)

Returns: `body` (object), `direction` (string), `encoding` (string), `from` (object), `id` (string), `messaging_profile_id` (string), `organization_id` (string), `received_at` (date-time), `record_type` (string), `to` (array[object]), `type` (string), `wait_seconds` (float)

Generate RCS deeplink

Generate a deeplink URL that can be used to start an RCS conversation with a specific agent.

`GET /messages/rcs/deeplinks/{agent_id}`

response = client.messages.rcs.generate_deeplink(
    agent_id="550e8400-e29b-41d4-a716-446655440000",
)
print(response.data)

Returns: `url` (string)

List all RCS agents

Returns RCS agents available to the authenticated account.

`GET /messaging/rcs/agents`

page = client.messaging.rcs.agents.list()
page = page.data[0]
print(page.agent_id)

Returns: `agent_id` (string), `agent_name` (string), `created_at` (date-time), `enabled` (boolean), `profile_id` (uuid), `updated_at` (date-time), `user_id` (string), `webhook_failover_url` (url), `webhook_url` (url)

Retrieve an RCS agent

Returns the configuration and current state of the specified RCS agent.

`GET /messaging/rcs/agents/{id}`

rcs_agent_response = client.messaging.rcs.agents.retrieve("550e8400-e29b-41d4-a716-446655440000",
)
print(rcs_agent_response.data)

Returns: `agent_id` (string), `agent_name` (string), `created_at` (date-time), `enabled` (boolean), `profile_id` (uuid), `updated_at` (date-time), `user_id` (string), `webhook_failover_url` (url), `webhook_url` (url)

Modify an RCS agent

Updates the supplied configuration fields on the specified RCS agent.

`PATCH /messaging/rcs/agents/{id}`

Optional: `profile_id` (uuid), `webhook_failover_url` (url), `webhook_url` (url)

rcs_agent_response = client.messaging.rcs.agents.update(
    id="550e8400-e29b-41d4-a716-446655440000",
)
print(rcs_agent_response.data)

Check RCS capabilities (batch)

Returns RCS capability information for multiple recipients in one request.

`POST /messaging/rcs/bulk_capabilities` — Required: `agent_id`, `phone_numbers`

response = client.messaging.rcs.list_bulk_capabilities(
    agent_id="TestAgent",
