ekreta-docs v3

Notice: I no longer have access to a Kreta account. As such, I am looking for a maintainer to take over this project and allow it to remain up to date. Email me for details!

Updated documentation for version 3 of the e-kreta API.

Most of the info here is based on Filc's source code and boapps' v1 documentation, while the rest was hand tested.

The repository also contains a Python program to access most functions, and as a sort of example of usage.

General Disclaimer

It seems that not all schools use the ekreta.hu API link. If you get an HTTP 301 - Moved Permanently response, try changing your domain to e-kreta.hu instead. (#4)

Kreta projects based on the new API

Filc: An unnofficial e-diary application for the e-Kreta system.
Asztal: Terminal-based e-Kreta client.
kreta-cli: A command line interface for KRÉTA's latest v3 api
Táblafilc: A grade calculator program for students (GitHub).

To add your project to the list, create a pull request with it added.

Getting current API links

Useful so that if the api links change you don't have to update your app.

Technically it is available from a normal browser as well.

Getting list of all Kreta schools

May not work in languages with no lowercase header request, like Swift and Dart, see BoA's note.

curl -H "apiKey: 7856d350-1fda-45f5-822d-e1a2f3f1acf0"  https://kretaglobalmobileapi2.ekreta.hu:443/api/v3/Institute

Access & Refresh token

Access token

Returns a Bearer authenticator to be used later for most requests.

NOTE: Sometimes it seems to return a 502 error, not sure why or if it's a problem I can fix.

NOTE: To simplify the X-AuthorizationPolicy-Key and X-AuthorizationPolicy-Nonce header information, please refer to the kreta_v2.py file.

curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -H "User-Agent: hu.ekreta.student/1.0.5/Android/0/0" -H "X-AuthorizationPolicy-Key: xxx" -H "X-AuthorizationPolicy-Version: v2" -H "X-AuthorizationPolicy-Nonce: xxx" -d 'userName=xxxxxxxx&password=xxxxxxxxx&institute_code=xxxxxxxxx&grant_type=password&client_id=kreta-ellenorzo-mobile' https://idp.e-kreta.hu/connect/token

Response from server:

{
 "access_token":"XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
 "refresh_token": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
 ...
}

Refresh token

With grant_type=refresh_token you can then refresh your access token:

curl -H "Content-Type: application/x-www-form-urlencoded" -H "User-Agent: hu.ekreta.student/1.0.5/Android/0/0" -d "institute_code=xxxxxxxxx&refresh_token=xxxxxxxxxxxx&grant_type=refresh_token&client_id=kreta-ellenorzo-mobile" https://idp.e-kreta.hu/connect/token

Messages

Get all messages

Requires the same headers as all GET requests, but also needs an endpoint that can be beerkezett, elkuldott or torolt.

curl -H 'Authorization: Bearer xxxxxxxx' -H 'User-Agent: hu.ekreta.student/1.0.5/Android/0/0' https://eugyintezes.e-kreta.hu/api/v1/kommunkacio/postaladaelemek/$type

Get information about a specific message

The above method is limited in message length (I think to 100 characters), so this gets more info about a specific messages denoted by it's numeric id.

Get information about student

Used to be together with absences & evaluations, but has it since been separated with v2.

Important notes:

"SzuletesiDatum" represents 00:00 of the given date, but is in UTC time: YYYY-MM-(DD-1)T23:00:00Z.
"TestreszabhatoBeallitasok" shows if the school allows things like student-submitted homeworks, showing themes of lessons, displaying class averages or even a global delay in evaluations showing up for whatever reason.

Important Notes:

type_of_eval seems to have the same values possible as Pre-Announced
Leiras looks to be the way to differentiate mid/half/endyear grades
SulySzazalekErteke is usually 100/200, but I've seen end of term grades registered at 150 so it's better to code it flexibly.

I've only listed and examplified what I think is probably the most used parts, or ones with peculiarities.

Everything else listed in the classes that's not mentioned should follow the same header format as seen above.
