how to set dynamic price

Not sure what you mean about being dynamic but you can use URL queries:

If you want it structures differently let me know.

in my case price value is not static. it may change by every 1 hour or every day

Where does this price come from?

How are you calculating the amount?

https://deen.seoxpertise.org/ check this website. price may increase or decrease when a user licks buy now current price value to be added in cart. Is it possible in this plugin

You need to capture the price when the ‘buy now’ button is clicked. This can easily be done with a script.

That’s the only way the plugin will work with dynamic pricing.

yeah using script i can get current price but how to pass the current price with plugin short code

To get this to work you just need a script to grab the amount from wherever and inject it into the plugin. Not sure what else I can do as the script will have to be bespoke to your website (because I have no idea where the amount is being generated and in what format).

I got current price using script but no idea to pass the amount value during payment

If you want a solution you need to get in contact with your website details and I will see what can be done.

I can’t offer any solutions on the support forum without access to the site and the script that generates the amount.
