no :S, do you want me to attach the whole zip file from paypal ?

[soak]

No, just trying to hint that maybe reading the docs that came with the script would be a better / faster way to get help. If you then get stuck then post your specific problem.

 

There's bound to be a simple example in the docs that you can copy / edit.

You need to look around more on the paypal website. Download the API integration guide...or something similar to that. I can't give you specific advice on the SOAP method since I use NVP, but I know there is a PDF out there with all the information you need.

 

However, after seeing your other post, I don't think the paypal API is what you're looking for. With the API you collect the credit card information directly on your site, and send all the information to paypal. DoDirectPayment is using credit cards, not paypal accounts. You'll want the express pay API if you're looking to have people pay with paypal only. If you don't really know what you're doing I don't recommend you collect any credit card information on your site. If your security is lax you could be held liable for any losses. Not to mention it will be easier for someone to defraud you. It's a good way to lose a lot of money, and it's a lot more complicated than a simple buy it now button.

 

Stick with the IPN for what you're trying to do. But you should be able to find all the information you need on the paypal API in the developer section of their website. In fact, here's a link directly to the documentation: https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/library_documentation
