In advance

Preparation steps

Install the plugin

Download and install INPOL Booking Assistant plugin by SLOT TAKER

Installation guide

Pay for license

You can pay for the license to work with the application within the plugin interface. We guarantee a refund if you are unable to book a slot. Please note that booking slots on the official INPOL website is free!

Plugin setup

Setup before slots appear

Log in to INPOL

Go to inpol.mazowieckie.pl and log in using your username and password.

Select scanning dates

In the plugin, open your application and mark preferred dates for booking. Be sure to enable local cell scanning with an interval of once every 10 seconds

Booking process

Algorithm of actions when a slot is detected

Slot appearance time is determined by INPOL administration. To study slot appearance patterns, we recommend reviewing the monitoring history.

1

Reset data

5-10 minutes before booking starts, click the "Reset" button to clear temporary INPOL data in the browser and reload the page.

2

Wait for INPOL to load

Focus on the 4 loading indicators: ideally all indicators should be green. Without the first two — booking requests will almost certainly not work.

3

Wait for slots to appear

Wait until slots become available on the booking page.

Color indication by detection time:

Green slots
less than 10 seconds
maximum chances
Yellow slots
up to 1 minute
average chances
Red slots
over 1 minute
minimum chances

4

Try booking slots

Click on a slot to attempt booking it. Try to book when slots just appear or become green.

When booking, there are 5 possible responses from INPOL:

HTTP 503/504
What it means:
INPOL website is unavailable due to high traffic.
What to do:
Try booking only green slots. Yellow and red — only if there are no green slots for a long time or slots are running out.
HTTP 403
What it means:
INPOL partner service is blocking your booking request.
What to do:
Press the "Reset" button and wait for green indicators (steps 1 and 2).
HTTP 428
What it means:
INPOL requested a captcha.
What to do:
The plugin automatically checks the box and clicks the button in the captcha. INPOL receives metrics collected from your real actions — that's why it's important to use manual booking. If at some point you see error 428, try pressing "Reset" and wait for green indicators (steps 1 and 2).
HTTP 400
What it means:
Either the slot has ended or INPOL is blocking your booking request.
What to do:
Try to avoid parallel booking attempts. Launch parallel booking only if the previous attempt has been stuck for more than 1-2 minutes or slots are running out.
HTTP 200
What it means:
Congratulations! Slot successfully booked.
What to do:
Write a review about SLOT TAKER and recommend to friends :)

Important Tips

Follow these recommendations for maximum efficiency

Don't make too many requests!

Frequent booking attempts won't speed up the process: INPOL may block your requests, and system load will only increase. Act calmly and steadily — this way you'll succeed.
