+## List GDT Transactions
+`GET http://localhost/api/listGDTTransactions/[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)
+

+  - `amount`: amount of payed money in euro, expect by gdt_entry_type_id = 7, then it is GDT Sum for Global Modificator time span
+  - `date`: date of transaction with let create gdt transaction, date for picking factor and Global Modificator
+  - `comment`: custom comment or Global Modificator name if gdt_entry_type_id = 7
+  - `gdt_entry_type_id`: type of gdt entry
