Hi Experts,
I am trying to communicate with the Paygate Payment Gateway, it basically works like this in a nutshell:
STEP 1 - Send the Paygate Server some parameters (Merchant ID, Amount, Reference etc etc...) to Initiate a Transaction.
- Server Responds with a 'PAY_REQUEST_ID' for the transaction.
STEP 2 - Use the PAY_REQUEST_ID (Gotten in Step 1) along with some other parameters and do a Redirect to their Payment's Web page with these parameters to
accept payment.
STEP 3 - Server will redirect to a Return URL and a Query Request can be sent to see if the Transaction has succeeded.
I have STEP 1 working 100% and I get a PAY_REQUEST_ID, STEP 3 I have not done yet.
Now STEP 2 is my problem, basically I am not so sure if I am doing it the right way?
What I get from the Server Response is the RAW HTML of the Payment's page, and I just assign this RAW HTML to a Webview control.
Now this works and I can see the Payment's page and I can also see the correct amount and reference listed there, but is this the correct way of doing it?
Here is the Paygate API docs:
docs.paygate.co.za
Here is the 'POSTMAN' docs showing Java OKHttp etc:
documenter.getpostman.com
Basically what I am doing is this for STEP 2:
Any advice/help would be greatly appreciated.
Regards,
Jacques.

PayWeb3
PayWeb is an easy and secure way to accept payments online. The Customer makes payments using PayGate’s secure hosted payment page. PayWeb is mobile-friendly making it compatible across all mobile devices. By selecting PayWeb, the Merchant gets immediate access to an array of Payment Methods...
Basically what I am doing is this for STEP 2:
B4X:
Private mHTTPClient As HttpJob
mHTTPClient.Initialize("HTTPClient",Me)
Dim strChecksum As String = GenerateMD5Checksum
mParametersMap.Clear
mParametersMap.Put("PAY_REQUEST_ID", mReturnedPayRequestID)
mParametersMap.Put("CHECKSUM", strChecksum)
mHTTPClient.PostMultipart("https://secure.paygate.co.za/payweb3/process.trans",mParametersMap,Null)
mHTTPClient.GetRequest.Timeout = mTimeout
mHTTPClient.GetRequest.SetHeader("Content-Type","text/plain")
Dim mRequestResponseString As String
'Wait for the Paygate Server to Respond....
Wait For (mHTTPClient) JobDone(mHTTPClient As HttpJob)
If mHTTPClient.Success Then
mRequestResponseString = mHTTPClient.GetString 'This contains the RAW HTML of the Payment's page.
mBrowser.LoadHtml(mRequestResponseString) 'Assign this RAW HTML to my Webview
End IfAny advice/help would be greatly appreciated.
