CoWIN: Vaccinator ? Extension

After installation, visit the CoWIN self-registration portal.
You'll see a button to start the bot. Click on that button, fill in your details, and click on book my vaccine.
The bot will automatically fill in all your details on the CoWin website, and you only need to enter the OTP.
Once you enter the OTP, the bot will continuously search for available slots, and if found, it will auto-book it for you.

## Advanced Features

Superfast login
The bot saves your mobile number so, in case of log out, you only need to provide the OTP for a superfast login experience.

Multiple Pin Code
You can enter multiple comma(,) separated pin codes. The bot will search for the vaccine availability at all provided pin codes one by one.

Search By State & District
You can also search for vaccine availability with State & District. You can only search with pin codes or state and district.

Multi-User Accounts
The bot supports accounts with multiple registered members. You need to select the correct Member Number On Dashboard. Example: If you have 3 registered members in one account, you can use this bot to book vaccines for all the 3 members one by one. You just need to provide the correct member number(the order in which they are present on the dashboard) for every member on the dashboard.

Dose 2
The bot also supports automated superfast booking for the second dose of vaccine.

Vaccine Preference
You can select the vaccine type from Covishield / Covaxin / Sputnik. You can also limit your search for only free vaccines.

Choose Vaccine Centre
If Let Me Choose The Vaccination Center is checked, the bot will hide all unavailable slots so you can choose the vaccine center from the list of all available centers, based on your preference.

Autobook
If Autobook is selected, the bot will automatically select the available vaccination center and a time slot to autocomplete the booking for you.

Retry Interval
The interval after which the bot should retry searching. CoWIN allows 20 searches within 15 mins, please provide this value responsibly.

Rate Limit Pause
If selected, the bot automatically pauses after it reaches the 20 search rate limit in 15 mins and it automatically continues after the cool-down period.

Audio Alerts
You get an audio alert when a slot is found or when you need to enter your OTP so that you never miss the opportunity to book a slot.


*In case the bot is stuck or behaves unexpectedly, stop the bot and try refreshing the page.
**All the data provided by you always stay on your computer. It is not stored/shared anywhere else.

raju r (ID: 000000714c77da99) Voted 2 ★ - Updated 08/05/2021 when after 20 search its saying *Rate Limit Pause so i see your comment like this Version 2.2 now supports *Rate Limit Pause*. The bot automatically pauses after it reaches the 20 search rate limit in 15 mins and it automatically continues after the cool-down period so wat we do rate limit pause are we logout and log in again or wait,,, if we wait at that time vaccine comes what we do,,, i think old ver is better 20 search logut automatically that the best
