# PayTM | Django REST Framework
**A package for PayTM integration in Django REST Framework**<br>
`PayTM | Django REST Framework` is a Django packaged app that provides necessary `views` based in Django REST Framework.
It enables easy integration of PayTM Payment Gateway with Web/Mobile Application with a RESTful API based server.

### Frontend API Integration Guideline
1. Prepare `json` data to post on `request/` view: `{"oid": "ORDER_ID", "amount": "200", "callback_url": "FRONT_END APP URL"}`
2. `callback_url`: FrontEnd URL to open when payment is successful. Must not have any queryset as `?oid=ORDER_ID` is
appended.
3. Post to `request/` and parse response to prepare a HTML form as per code shown below.
4. Don't add `<input>` for empty and `null` fields from json response of `request/` API.
5. Set `CALLBACK_URL` in HTML from `paytm_callback_url` of JSON.
6. Once the payment is done, user is redirected to `response/` view which will verify payment.
7. If payment is verified by Django Backend, user is redirected to `http://callback_url?oid=ORDER_ID`.
8. Access `order/ORDER_ID/` API to get `is_completed` status. If it's `false`, check `last_payment_status`.
**Note: In case of critical failure, server's JSON response is shown.**
Sample HTML Code to be generated by FrontEnd App(from PayTM)
```

<title>Merchant Check Out Page</title>

### MODELS
The application has three models:
- `PayTMConfiguration`: You need to define your PayTM configurations in this model. Only one object can have
`is_active` set to `True` which will be used with PayTM API.
- `TransactionRequest`: This will contain all the PayTM Transaction Request that one will create with PayTM.
- `TransactionResponse`: This will contain all the responses received from PayTM API against transaction.
### VIEWS
The application has following views:
- `ListAddTransactionRequestView`: All payment request should be made on this view. Requires a logged in user.
It'll provide user with required data, including `checksum hash` that will be used with PayTM API.
- `AddTransactionResponseView`: Response from PayTM is posted on this view. URL for this view should go as
`CALLBACK_URL`. This view then redirects user to FrontEnd app with `OID` as queryset parameter.
- `PayNowTransaction`: This view is for testing w/o a frontend client. It will open PayTM payment page.
### URLS
- `request/`: All payment request to be made via this URL.
- `response/`: All response from PayTM is posted on this URL.
- `order/OID/`: Retrieve specific payment request data.
- `now/`: For immediate testing of API, open this url.
### Quickstart Guide
- Complete `Installation Steps` (mentioned above)
- Create a configuration via `Django Admin` in `PayTM Configuration`.
- Provide `base_url` of your Backend Server.
- Set `is_active` to `True`
- Note: Use sandbox mode credential at first
- Test API by accessing `/api/paytm/now/` endpoint
- Use `PayTM Testing Credential`:
