Calling https link that is not a web service

Stephen3 — Tue, 19 Jun 2012 15:12:51 GMT

Hi All;

I have a need to call a credit card clearing house. Specially the URL https://secure.authorize.net:8080/gateway/transact.dll'

There is no WSDL or web service for this URL.

I am trying to use the method cl_http_client=>create_by_url but I can't seem to get it working.

Does anyone have any code samples they can share?

I am using a Linux Red Hat 5 system with SAP ECC 6.0 EHP4.

Thanks

Stephen

Hi Stephen,

can you please explain where your problem is?

The ABAP part (cl_http_client) or the Basis part (installing the SSL certificate)?

The test transaction is well documented here: http://developer.authorize.net/guides/DPM/wwhelp/wwhimpl/js/html/wwhelp.htm

Best regards

Hi Uwe;

My problem is the ABAP part. There are number of sample code examples on the authorize.net website, but none for SAP ABAP. Also, I am trying to use the AIM process described by Authorize.net. You provided a link to the DPM process. Is DPM a better process?

Hi Stephen,

so you have already imported the SSL certificate?

The ABAP part for the test transactionis quite simple:

- create the client (with url = secure.authorize.net/gateway/transact.dll and SCHEME = https)

- send a POST (with field x_test_request = "TRUE")

- receive the response

- close the connection

(code samples for CL_HTTP_CLIENT you can find all around SCN).

If the test transaction works for you, all other transactions should be no problem

Regards

Uwe

Hi Uwe,

How do I then pass the value like CC #, Amount - Shall I use http_client->request->set_header_field method?

Thanks.

Hi Bharat;

Here is the code of the function module I used to call our credit card clearing house:

It reads the credit card number from the contact table associated with the customer master record. This way a customer can have multiple credit cards on file.
