I spent MONTHS trying to integrate PayPal into my website, followed countless tutorials, articles - I read all the documents, downloaded countless samples and the so-called "full working samples" and still haven't got a job.
I also asked a few questions in individual cases, right here in S / O (under the old, now canceled account), which did not lead to the correct answers.
I just stumbled upon the website www.x.com and read it. I'm going to give him another try, but before I do this, I would like to know if,
Getting started 1. Check the status of your account. Sign in to PayPal. Go to your PayPal profile and click on "My Settings." Confirm that your account type is either Premier or Business, or upgrade your account.
2. Check the API settings. Click "My Selling Tools." Expand Online Sales if necessary and check API Access. Click Refresh and Add or Modify. API or View API.
3. In your PayPal profile, click "My Selling Tools", click "Instant Alert." Follow the instructions to enable your IPN including entering notification URLs.
4. To create a basic IPN script listener, use the PayNal IPN script generator. If necessary, modify the script to suit your needs.
5. Install the script on your website at the notification URL specified in your PayPal profile. 6. Try using a script using Sandbox in PayPal. (Registration is free.)
7.After you have verified that your implementation works correctly in the Sandbox, you are now ready to live life.
What above quoted text (from https://www.x.com/developers/paypal/products/instant-payment-notification ) is really all I need, as they say?
Are there other things that are not related to the documentation, or are there other things you need to know to integrate PayPal IPN into your website that are not easily accessible through PayPal or X.com sites?
