Dwolla Payments module

Does anyone know how to create/ integrate a Dwolla payments module? (Dwolla: U.S. based system which offers electronic payments for $0.25/ transaction vs. 3%+ for paypal).

mmwilcox,

Dwolla is something I just learned about by accident a couple weeks ago - they are here in Des Moines even! So not being much of a programmer, but a zen cart user (must have some programming skills for customizing ZC, right?) I went to one of their meetup events and was very impressed.

Anyway it looks like a fantastic service that will doubtless take off b/c of the awesome fee structure and ease of use.

Anyway, I'm 99% sure that I've successfully ported the oscommerce module to Zen Cart using the ZC wiki article on porting modules from osc.

Maybe this weekend I'll find out more. I just want you to know someone is working on it and I may be posting it soon.

Thanks John. I look forward to seeing it.

I'd like to offer a discount of 1 or 2% for using Dwolla. Its still less than the credit charges we pay. Anyway, being a remedial programmer, I was able to modiffy the Dwolla setup to allow the admin to set a discount amount. Then, when checking out, it would calculate the discount and net amounts and feed those to the Dwolla Hub for the user.

It worked perfectly except when a coupon was used. I was unable to grab the after-coupon total to determine the appropriate discount and net payment amount.

I would be happy to share what i've done thus far if you are interested in the discount feature.

Thanks,

Here it is. Okay it won't allow me to upload the files b/c they exceed the maximum.

I tested it and found it works with my version 1.3.9fp1.

It requires you to check your email and enter the random code that was emailed to you to complete the checkout. (I kept entering my Dwolla PIN number and it kept rejecting the transaction at first.)

Yes I'm interested in having the price discounted by 2% or something when users choose this method of checkout, but I really don't know where to start on coding this. Maybe in the 'orders.php' file? If you know anything more then I'd be interested in your approach.

Thanks!

Here it is.

EDIT:
(Okay it won't allow me to upload the files b/c they exceed the maximum. So I uploaded the files I could as "languages.zip" and "modules.zip". These have the 2 files that need to be put in the "includes" folder while retaining the file structure. For this module to work it also needs the xml/SOAP library in the "includes/modules/payment/lib" folder, which can be downloaded here: http://addons.oscommerce.com/info/7732.
Extract the files, then only use the xml library "includes/modules/payment/lib")

Hint: There is one other thing to consider with this type module is that it is using SOAP so you may have to have your web host enable SOAP on your web server.

I tested this and found it works with my version 1.3.9fp1.

Thanks and nice work.

Here are the two files that I worked on to create a percentage discount. Perhaps there are some pieces that you or someone will find helpful.

Good luck.
