Simple Merchant Server Implementation Reference for Mobile SDK (Python version).

Description

This is a example mobile SDK server for Midtrans's iOS and Android SDK, as an implementation reference to use the mobile sdk. Please read more in Documentation of Midtrans mobile SDK.

Purpose

The main idea why this server implementation needed is: To securely add HTTP Authorization Header from server side. This auth header is generated from server key (from your Midtrans account), this server key is secret, and should only be kept in server side, not client side (mobile app can be easily reverse engineered to extract any secret).

Additionally, it allows you to tweak JSON request parameter as needed from server side.

Prerequisites

You need these to run the app:

• Python 2.7.x

Install dependencies

$ pip install -r requirements.txt

Running the app

$ export FLASK_ENV=development
$ python app.py / flask run

Endpoints

There is only one endpoint that are required to use Midtrans mobile SDK:

POST /charge

This endpoint will proxy (forward) client request to Midtrans Snap API 'https://app.midtrans.com/snap/v1/transactions' (or 'https://app.sandbox.midtrans.com/snap/v1/transactions' for sandbox) with HTTP Authorization Header generated based on your Midtrans Server Key.

The response of API will be printed/returned to client as is. Example response that will be printed

{
    "token": "413ae932-471d-4c41-bfb4-e558cc271dcc",
    "redirect_url": "https://app.sandbox.midtrans.com/snap/v2/vtweb/413ae932-471d-4c41-bfb4-e558cc271dcc"
}

Usage

Edit file config.yml, insert your Midtrans Account Server Key to sandbox_server_key and production_server_key. Set is_production to True when you use env production.

Set <url where you host this>/charge as merchant base url in mobile SDK. (refer to Midtrans mobile SDK doc)

Testing

You can mock client's request by executing this CURL command to the /charge endpoint:

curl -X POST \
   http://<your url>/charge \
  -H 'Accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{
    "transaction_details": {
        "order_id": "mobile-12345",
        "gross_amount": 280000
    },
    "item_details": [
        {
            "id": "A01",
            "price": 280000,
            "quantity": 1,
            "name": "Mie Ayam Komplit"
        }
    ],
    "customer_details": [
        {
            "email": "[email protected]",
            "first_name": "Budi",
            "last_name": "Khannedy",
            "phone": "628112341234"
        }
    ]
}'

Note: dont forget to change "http://<your url>/charge" to your url where you hosted the /charge.

You can also import that curl command to Postman.

Notes

This is just for very basic implementation reference, in production, you should implement your backend more securely.
