This issue is completely related to your API credentials that you put under your env file. In my case, I am giving the wrong paytm_merchant key.

So you just have to recheck your credentials provided by Paytm. To get your API credentials you have to visit the following link https://dashboard.paytm.com/
In the sidebar under the Developers section, you can find the API keys as well as the API documentation.
