# Telnyx Webrtc - Python

## Installation

```bash
pip install telnyx
```

## Setup

```python
import os
from telnyx import Telnyx

client = Telnyx(
    api_key=os.environ.get("TELNYX_API_KEY"),  # This is the default and can be omitted
)
```

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:

```python
import telnyx

try:
    result = client.messages.send(to="+13125550001", from_="+13125550002", text="Hello")
except telnyx.APIConnectionError:
    print("Network error — check connectivity and retry")
except telnyx.RateLimitError:
    # 429: rate limited — wait and retry with exponential backoff
    import time
    time.sleep(1)  # Check Retry-After header for actual delay
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")
```

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 methods return an auto-paginating iterator. Use `for item in page_result:` to iterate through all pages automatically.

## List mobile push credentials

`GET /mobile_push_credentials`

```python
page = client.mobile_push_credentials.list()
page = page.data[0]
print(page.id)
```

Returns: `alias` (string), `certificate` (string), `created_at` (date-time), `id` (string), `private_key` (string), `project_account_json_file` (object), `record_type` (string), `type` (string), `updated_at` (date-time)

## Creates a new mobile push credential

`POST /mobile_push_credentials` — Required: `type`, `certificate`, `private_key`, `alias`

```python
push_credential_response = client.mobile_push_credentials.create(
    create_mobile_push_credential_request={
        "alias": "LucyIosCredential",
        "certificate": "-----BEGIN CERTIFICATE----- MIIGVDCCBTKCAQEAsNlRJVZn9ZvXcECQm65czs... -----END CERTIFICATE-----",
        "private_key": "-----BEGIN RSA PRIVATE KEY----- MIIEpQIBAAKCAQEAsNlRJVZn9ZvXcECQm65czs... -----END RSA PRIVATE KEY-----",
        "type": "ios",
    },
)
print(push_credential_response.data)
```

Returns: `alias` (string), `certificate` (string), `created_at` (date-time), `id` (string), `private_key` (string), `project_account_json_file` (object), `record_type` (string), `type` (string), `updated_at` (date-time)

## Retrieves a mobile push credential

Retrieves mobile push credential based on the given `push_credential_id`

`GET /mobile_push_credentials/{push_credential_id}`

```python
push_credential_response = client.mobile_push_credentials.retrieve(
    "0ccc7b76-4df3-4bca-a05a-3da1ecc389f0",
)
print(push_credential_response.data)
```

Returns: `alias` (string), `certificate` (string), `created_at` (date-time), `id` (string), `private_key` (string), `project_account_json_file` (object), `record_type` (string), `type` (string), `updated_at` (date-time)

## Deletes a mobile push credential

Deletes a mobile push credential based on the given `push_credential_id`

`DELETE /mobile_push_credentials/{push_credential_id}`

```python
client.mobile_push_credentials.delete(
    "0ccc7b76-4df3-4bca-a05a-3da1ecc389f0",
)
```

## List all credentials

List all On-demand Credentials.

`GET /telephony_credentials`

    connection_id="1234567890",
)
print(telephony_credential.data)
