Community Server API
This document describes the community server API. The community server is written in PHP and mixes front with backend. Furthermore cakePHP and its auto-generated controller structure is used to access the API. This whole part of the Software will be subject to refactoring.

Account overview
Returns the current account balance
Request
GET http://localhost/api/getBalance/
Response
Assuming: session is valid
Session will be searched in php session and GRADIDO_LOGIN cookie.
Additional session can be provided as GET-Parameter
GET http://localhost/api/getBalance/-127182
{
"state":"success",
"balance":1590.60,
"decay":1587.38,
"decay_date":"2021-04-16T11:47:21+00:00"
}
balance: balance describes gradido as float with max two decimal placesdecay: balance with decay on it at the time in decay_date, so it is the precise balance of user at time of calling this functiondecay_date: date and time for decay amount, should be the time and date of function call
List transactions
List all transactions for logged in user
Request
GET http://localhost/api/listTransactions/[1]/[25]/[DESC]/[session_id]
Parts symbolized by [] are optional
- first parameter (1) is page for paging
- second parameter (25) is count for paging
- third parameter is ordering of resulting array, default is ASC
- fourth parameter is session_id (session will be searched in php session and GRADIDO_LOGIN cookie and if not found use this )
Paging
With count you say how many entrys you like to have in the result. With page you say on which page you are. For example 50 transactions are in db. With 1/25 you get the first 25 transactions (1-25) With 2/20 you get the second 20 transactions (21-40)

Creation transaction
Makes a creation transaction to create new Gradido
This assumes you have set
unsecure.allow_auto_sign_transactions = 1
in the Login-Server, so transactions can be auto-signed directly with handing in the transaction. Normally a forwarding to login-server check transactions side is necessary to minimize security risks. // TODO this is not documented

Send transaction
Make a simple GDD Transaction, send Coins from logged in user to another.

In case of success returns:

Process
Once the transaction was created on community server, send to login-server, signed (if unsecure.allow_auto_sign_transactions = 1 and auto_sign = true) and then send back to community server to be finally put into the database.
After you get this answer you see the new transaction if you request the transaction list or call for the balance.
// TODO balance and at least last transaction must be returned with the call itself
Without auto-sign the transaction is pending on the login-server and waits for the user to review it at http://localhost/account/checkTransactions
// TODO how is this more secure? // TODO Is this in line with our usability goals? // TODO Should this not be handled client side?
