If you have problems with the code in this repository, please file an issue or a pull-request. Thanks!

## Installation

```
pip install aioexponent
```

## Usage

Use to send push notifications to Exponent Experiences from a Python server.

[Full documentation](https://docs.expo.io/versions/latest/guides/push-notifications.html#http2-api) on the API is available if you want to dive into the details.

Here's an example on how to use this with retries and reporting via [pyrollbar](https://github.com/rollbar/pyrollbar).
```python
from aioexponent import DeviceNotRegisteredError
from aioexponent import PushClient
from aioexponent import PushMessage
from aioexponent import PushResponseError
from aioexponent import PushServerError
from aiohttp import ClientError


# Basic arguments. You should extend this function with the push features you
# want to use, or simply pass in a `PushMessage` object.
async def send_push_message(tokens, message, extra=None):
client = PushClient()
try:
response = await client.publish_multiple([
PushMessage(to=token,
body=message,
data=extra) for token in tokens])
except PushServerError as exc:
# Encountered some likely formatting/validation error.
rollbar.report_exc_info(
extra_data={
'tokens': tokens, 'message': message, 'extra': extra
'errors': exc.errors,
'response_data': exc.response_data,
})
raise
except (ClientError) as exc:
# Encountered some Connection or HTTP error - retry a few times in
# case it is transient.
rollbar.report_exc_info(
extra_data={'tokens': tokens, 'message': message, 'extra': extra})
raise retry(exc=exc)

try:
# We got a response back, but we don't know whether it's an error yet.
# This call raises errors so we can handle them with normal exception
# flows.
response.validate_response()
except DeviceNotRegisteredError:
# Mark the push token as inactive
from notifications.models import PushToken
PushToken.objects.filter(token=token).update(active=False)
except PushResponseError as exc:
# Encountered some other per-notification error.
rollbar.report_exc_info(
extra_data={
'tokens': tokens,
'message': message,
'extra': extra,
'push_response': exc.push_response._asdict(),
})
raise retry(exc=exc)
```
