Sandbox

Implementation of an API test server that returns JSON encoded accounts and transactions - no database, dynamic generation of data, almost stateless.

routes

GET /accounts
GET /accounts/:account_id
GET /accounts/:account_id/transactions

basic_auth -> Api Token in user field

simple basic auth in Router
Api Token opaque
can be generated
state inside: start balance and offset for generating dynamic data - see Token

generate example data

look into Account or Transaction

API Token generation

  mix help sandbox.gen.token

Generate a new Api Token:

  mix sandbox.gen.token start_balance:float offset:integer

Example:

  mix sandbox.gen.token 999999.12 8

The first argument is any start balance with 2 decimal places (more decimal places are cut off). The second argument is an offset integer to generate dynamic values from the given lists.

To use this generated api token please put it into config.exs:

  config :sandbox, sandbox_api_token: ["first_token", "second_token"]

alternatively and more secure is ENV var handling (separation with ":"):

  export SANDBOX_API_TOKEN=first_token:second_token

Token generation via http request

Because it's for dev testing - any tester could create automatically their own token.

added route:

GET /token

response:

{
    "token": "test_api_GBXKTT42_H3WBFSSY"
}

Todo:

Maybe some more stuff like:

Balance amount check - because transaction could run out of money if the balance was to low (maybe allow negative balance???)
