Hello Manju–thanks for reaching out and we’re stoked you’re considering our plugins for your project. 🙂
Good question. The WooTickets add-on will certainly allow you to create and sell tickets for the events you publish to the site.
Then, there is our Community Events add-on which will allow your vendors to submit events to the calendar from the front end of the site.
While those two add-ons are great for those sole purposes, they unfortunately do no work together. In other words, it is not currently possible for one of your vendors to submit an event to the calendar and create tickets for the event. It’s something we’re looking into but is currently not provided right out of the box.
Does this help answer your question? Please let me know. 🙂
Cheers!
Geoff
