Add below line to declaration.d.ts file

In SuccessCallback method, you will get response object as json, with infromation present in http://paywithpaytm.com/developer/paytm_api_doc?target=interpreting-response-sent-by-paytm

var successCallback(response) {
    if (response.STATUS == "TXN_SUCCESS") {
        var txn_id = response.TXNID;
        var paymentmode = response.PAYMENTMODE;
        // other details and function after payment transaction
    } else {
        // error code will be available in RESPCODE
        // error list page https://docs.google.com/spreadsheets/d/1h63fSrAmEml3CYV-vBdHNErxjJjg8-YBSpNyZby6kkQ/edit#gid=2058248999
        alert("Transaction Failed for reason " + response.RESPMSG);
    }
}

var failureCallback(error) {
    // error code will be available in RESCODE
    // error list page https://docs.google.com/spreadsheets/d/1h63fSrAmEml3CYV-vBdHNErxjJjg8-YBSpNyZby6kkQ/edit#gid=2058248999
    alert("Transaction Failed for reason " + error.RESPMSG);
}

Expected "Options" that has to be send to the plugin to start the transactions is

{
  "REQUEST_TYPE": "DEFAULT",
  "MID": "PAYTM_MERCHANT_ID",
  "ORDER_ID": "ORDER0000000001",
  "CUST_ID": "10000988111",
  "INDUSTRY_TYPE_ID": "PAYTM_INDUSTRY_TYPE_ID",
  "CHANNEL_ID": "WAP",
  "TXN_AMOUNT": "1",
  "WEBSITE": "PAYTM_WEBSITE",
  "CALLBACK_URL": "https://securegw.paytm.in/theia/paytmCallback?ORDER_ID=ORDER0000000001",
  "EMAIL": "abc@gmail.com",
  "MOBILE_NO": "9999999999",
  "CHECKSUMHASH": "w2QDRMgp1/BNdEnJEAPCIOmNgQvsi+BhpqijfM9KvFfRiPmGSt3Ddzw+oTaGCLneJwxFFq5mqTMwJXdQE2EzK4px2xruDqKZjHupz9yXev4="
}

Response:

{
  "TXNID": "414709",
  "BANKTXNID": "",
  "ORDERID": "ORDER48886809916",
  "TXNAMOUNT": "1.00",
  "STATUS": "OPEN",
  "TXNTYPE": "SALE",
  "GATEWAYNAME": "",
  "RESPCODE": "",
  "RESPMSG": "",
  "BANKNAME": "",
  "MID": "klbGlV59135347348753",
  "PAYMENTMODE": "CC",
  "REFUNDAMT": "0.00",
  "TXNDATE": "2015-11-02 11:40:46.0"
}

CHECKSUM has to be created without "ENVIRONMENT" field, it is for plugin's internal use to determine which environment it's going to hit.

References: Various fields avialbale in "options" Doc on response from the plugin Logic to generate checksum Paytm guys suggests to verify the transaction status manually after the successful transaction. Refer this link to know about it

Note:

• Version 0.0.3 is not backward compatibile with 0.0.2. In v0.0.3, send options as JSON object where in 0.0.2, send each value separately i.e (txn_id, customer_id, email, phone, amount, callbackurl, environment,..,..)
• ENVIRONMENT info has to be part of 'options', which says the environment transaction has to be started. Possible values are 'staging' and 'production'.
• Send transaction amount in String format, as that is the format accepted in iOS platform.
