telstra.messaging 3.3.19
SDK for the Telstra Messaging API V3 - Beta
License: Apache-2.0
Requires Python: <4.0,>=3.10

# Telstra Messaging

The SDK for the Telstra Messaging API enables you to send and receive messages
to Australian mobile numbers. For more information about this product, please
see here:
<https://dev.telstra.com/docs/messaging-api/apiReference/apiReferenceOverview?version=3.x>.

> :warning: **This SDK is experimental, everything is subject to change**

## Installing

```bash
pip install telstra.messaging
```

## Getting Started

Set the `TELSTRA_CLIENT_ID` and `TELSTRA_CLIENT_SECRET` environment variables. These
are the `Client id` and `Client secret` you can find here:
<https://dev.telstra.com/user/me/apps>.

To send your first message:

```python
from telstra.messaging import message

message.send(
  to="+61412345678",
  from_="+61412345678",
  message_content="Hello from Python Messaging SDK!"
  )
```

To set the required environment variables if your application is in `app.py`:

```bash
TELSTRA_CLIENT_ID"<client id>" TELSTRA_CLIENT_SECRET="<client secret>" python app.py
```

## Authentication

Authentication through environment variables, a shared credentials file
and through code are supported.

### Authentication using environment variables

Export the following two environment variables, replacing the values
with your own credentials.

```shell
export TELSTRA_CLIENT_ID="<client id>"
export TELSTRA_CLIENT_SECRET="<client secret>"
```

### Authentication using shared credentials

Create a `~/.telstra/credentials` file in your home path with the following contents,
replacing the values with your own credentials.

```markdown
[default]
TELSTRA_CLIENT_ID = <client id>
TELSTRA_CLIENT_SECRET = <client secret>
```

### Authentication using code

On top of the authentication through the `TELSTRA_CLIENT_ID` and
`TELSTRA_CLIENT_SECRET` environment variables
and a `~/.telstra/credentials` shared credentials
file, authentication through code is also supported.
For example:

```python
from telstra.messaging.utils.config import CONFIG

CONFIG.telstra_client_id = '<client id>'
CONFIG.telstra_client_secret = '<client secret>'
```

This should be done before any interactions requiring authentication, such as
sending a message.

## Free Trial

Telstra offers a free trial for the messaging API to help you evaluate whether
it meets your needs. There are some restrictions that apply compared to the
full API, including a maximum number of messages that can be sent and requiring the
registration of a limited number of destinations before a message can be sent
to that destination. For more information, please see here:
