I am also facing the same issue. Did anyone get any solution?

[RahulRijhwani]

i was also facing that issue and i found solution
Please check steps and parameters of generate checksum how to generate checksum
and same parameters pass with Paytm.startPayment

[HarishJangra]

you must generate checksum with same params as on server like if you dont send mobile or email on server then you must not send mobile and email on your client app. thats how it works i myself faced this problem while integrating. and please confirm them params keys in server side from paytm. I think they have typos in their docs.
here is an example in php server side

        include(__DIR__.'/../lib/encdec_paytm.php');
        $params = [
            'MID' => <your merchant id>,
            'ORDER_ID' => $data['order_id'],
            'CUST_ID' => <customer id>,
            'INDUSTRY_TYPE_ID' => <industrytype>,
            'CHANNEL_ID' => <channel>,
            'TXN_AMOUNT' => ''.$data['amount'], //has to be string
            'WEBSITE' => <website>',
            'CALLBACK_URL'=> "https://securegw-stage.paytm.in/theia/paytmCallback?ORDER_ID=".$data['order_id'],
        ];
        $merchantKey = <Your merchant key>;
        $checkSum = getChecksumFromArray($params, $merchantKey);
        return $checkSum;
