RE: Buy Now Paypal integration workflow
There are some utilities out there to help you with the integration. Using the Buy Now, you would send over a success_url or failed_url (I think that is correct) which would be a page within your website. Thus, you can take the appropriate actions as needed. -Original Message- From: Rick King [mailto:[EMAIL PROTECTED] Sent: Tuesday, October 03, 2006 4:39 PM To: CF-Talk Subject: Buy Now Paypal integration workflow Anyone ever have this issue when integrating a Buy Now button from Paypal? I have a site where a user posts a listing for an item, say a shirt. They are also allowed to upload 3 images for that item. I'm charge a listing fee that equals a percentage of the asking price of that item (say 5%). Once the user fills out the details, and uploads the images, they go to the review page.

Are you using Paypals IPN (Instant Payment Notification) feature. It will send you a data packet full of payment data when a transaction is completed. -- Ian Skinner Web Programmer BloodSource www.BloodSource.org Sacramento, CA - | 1 | | - Binary Soduko | | | - C code.

RE: Buy Now Paypal integration workflow
You need you use the IPN method, so that you have a callback that happens in the background.

RE: Buy Now Paypal integration workflow
Hi Rick, You should use the IPN (Instant Payment Notification) feature of PayPal. There is example ColdFusion code on the PayPal site for processing the IPN Post data that is returned to the page that you specify as the return page for the IPN. Essentially, the workflow could be: 1. User logs in 2. Create product and in database and set status to pending 3. Upload images and associate with product record 4. Click Buy Now Button and go to PayPal site (Buy Now Button has various properties you can set, some of which can be retrieved from the IPN Post data) 5. Have the IPN take the user back to thankyou.cfm 6. Read the IPN Post data inside thankyou.cfm 7. Update your product record status to completed Cheers, Martyn -Original Message- From: Rick King [mailto:[EMAIL PROTECTED] Sent: Wednesday, October 04, 2006 9:39 AM To: CF-Talk Subject: Buy Now Paypal integration workflow Anyone ever have this issue when integrating a Buy Now button from Paypal?

RE: Buy Now Paypal integration workflow
Hi, Rick... Sorry I don't have an answer for you, because I have no experience with ecommerce...however, I have thought of creating a virtual Mall for our area and allowing local merchants to sell their wares on the site. Is that what you're doing...or something similar?

Thanks guys...I didn't know about the IPN method. I'll look into it tonight.

Re: Buy Now Paypal integration workflow
So I tried implementing IPN, made all the preference changes on Payapl, read up on the lastest IPN tutorial over at easycfm by Mike Daugherty (http://tutorial468.easycfm.com/), and am using the code below. Unfortunately, I'm only receiving the contents of the cfelse statement which means it's not returning SUCCESS. I'm sure the authToken is correct. Has anyone else tried implementing this code? The whole process works great up until it returns to my ipn.cfm page.
