Read the Swagger documentation of the Kimai API in your Kimai installation at /api/doc
.
For example, you can have a look at the API docs for the demo installation at https://demo.kimai.org/api/doc.
You need to authenticate to see them, credentials can be found here.
Or you can export the JSON collection by visiting /api/doc.json
. Save the result in a file, which can be imported with Postman.
When calling the API you have to submit two additional header with every call for authentication:
X-AUTH-USER
- holds the username or emailX-AUTH-TOKEN
- holds the users API password, which he can set in his profileThe API calls can be exported in a Swagger file format, which can be imported into Postman.
You find the link in the API docs (the URL is api/doc.json
).
Simply export the swagger file and import it into Postman.
After importing the collection into Postman, edit the collection and switch to the Pre-request Scripts
tab.
You can add the following script to have a global authentication in-place, which you can still overwrite per call.
pm.request.headers.add({key: 'X-AUTH-USER', value: 'susan_super' });
pm.request.headers.add({key: 'X-AUTH-TOKEN', value: 'api_kitten' });
TL;DR
The API returns ISO 8601 formatted datetime strings in the users local time, including the timezone offset.
When POST
ing or PATCH
ing timesheet records, you MUST use the HTML5 format (see RFC 3336 as well).
Even if the API might allow different formats, only this one is guaranteed to work in the future.
It is also the only format that works correct, adding a timezone might and will result in unexpected and wrong records.
Please read this article to find out more about the “local date and time” pattern.
yyyy-MM-dd'T'HH:mm:ss
or Y-m-d\TH:i:s
(for example 2019-04-20T14:00:00
).YYYY-MM-DDTHH:mm:ss
or moment.HTML5_FMT.DATETIME_LOCAL_SECONDS
.Be aware: Kimai treats the given datetime as local time and adds the configured users timezone without changing the given time.
Read this comment to understand the backgrounds about that decision.
This example uses the API to import a list of customers, projects and activities from a CSV file.
First create the following composer.json
file and run composer install
afterwards.
{
"name": "kimai/api_demo",
"require": {
"guzzlehttp/guzzle": "^7.3",
"symfony/console": "^5.3",
"league/csv": "^9.7",
"ext-json": "*"
}
}
Now create a file with the name importer
and adjust the KIMAI_API_*
constants to your installation:
#!/usr/bin/env php
<?php
require __DIR__.'/vendor/autoload.php';
define('KIMAI_API_URL', 'https://127.0.0.1/api/');
define('KIMAI_API_USER', 'susan_super');

->run();
Set execute permission chmod +x importer
and start it by passing the filename for your CSV ./importer ~/kimai-import.csv
,
which should be formatted like this:
Customer,Project,Activity
DEMO,FOO,A long activity title
DEMO,FOO,Demand management
DEMO,BAR,Software as a service
DEMO,BAR,Administration
DEMO,BAR,Video conference
DEMO,BAR,Sales talk
DEMO,Hello world,I see you
DEMO,Hello world,Testing the API
If you develop your own plugin and need to use the API for logged-in user, then you have to
set the header X-AUTH-SESSION
which will allow Kimai to use the current user session and not look for the default token based API authentication.
Copy & paste this code into a new api.html
file and open it in your browser.
You can execute some sample requests and see the JSON result.
