How can I make an automatic PayPal buy button? - php

I want my PHP web application to have the ability to save the user's PayPal details in their user account.
When they go to purchase items, rather than going through the standard PayPal form, it will automatically grab the user's PayPal details from their user account, and make the payment directly from my website. There is definitely a way to do this, as I have seen this feature on sites such as Freelancer.com
Thanks for the help! :)

No, you don't need Payments Pro for that. That would only be if you want to do it with direct credit cards. What you're after in general is called Reference Transactions, and when done with PayPal Express Checkout it uses Billing Agreements.
You'll use Express Checkout and/or Payments Pro (optional) to process an original authorization or sale transaction. Then, you can send that ID you get back in that original transaction along with a new amount in the DoReferenceTransaction API and that new amount will be instantly processed without any redirection or further authorization required.

how do i link paypal account with online store using php

I am not sure what this is called but here is what i am looking to do.
I am trying to make a php script that will create a link between our store account and paypal buyer, so that when they click our buy button it will process the payment without any future confirmations or user actions.
I have tried the paypal sdks and integration wizard no luck, Does anyone know of a working example of what i am trying to do?
Billing agreement(also called Reference Transactions) allows customer to agree the payment once on your website or app, then you call an API with the billing agreement ID to tell PayPal to charge the customer. Please see document here . You will need to contact PayPal to enable you to use Billing agreement, it's not easy to get approval:(
Integrating Paypal buttons are pretty straightforward.
Go to your merchant account.
Go to your Create Paypal Button page.
Choose whatever the button types you want. Configure it with Price etc.
Now just copy and paste the code generated.
It just works.
P.S
There is an option in your merchant account page to set the returning address from Paypal. You can set a returning page and catch all the transaction details via HTTP Post method when it is called by Paypal.
There is this Sandbox account type in Paypal which you can do a lot of playing with.

Using paypal on custom website and accept credit / debit Card

I have an issue right now that is killing me, I have implemented several payment options but never used paypal, I don't know why is it so complicated.
The website already exists and wasn't developed by myself.
I don't know the ammount of the order it is dynamic, so the "create payment buttons" on the paypal website doesn't work for me, at this point i developed a solution using
PayPal developers
But it turns out that i only have the option to pay with a PayPal account or register a PayPal account, I do not want to force customers to do this, it has no sense. is there any relatively easy solution out there using the same PayPal API?
EDIT
The whole site code is in PHP so i need the solution in this language
As you have mentioned that you are aware of one payment method i.e. Express Checkout ( in which user needs to have a valid Paypal account) so the other method which I think you need is the Direct Payment (i.e. a user can pay with credit cards directly without any Paypal account) API.
For this direct payment api you need to enable Website Payment Pro WPP , here you can get info about WPP.

Confirm Express Checkout on PayPal via PHP

This question asked before but didn't got any answer.Maybe things have been changed.
When you click the Express Checkout PayPal button on any webshop, it redirects you to a specific paypal login link, for paying the order.
I have been searching high and low for 3 weeks for a simple paypal php curl script that logs you in from this step, and confirms the payment, but have not been able to find anything.
I found out it is not possible to use the API for this, so its gotta be done by CURL.
I'm asking for this because I run a dropshipping website, and would like to automate certain steps, like placing and paying orders. A working code for this would help not just me, but all looking to automate buying in some form.
Thank's!
You can't log the buyer into PayPal when you redirect them to the site. The buyer has to enter their own account credentials themselves.
If you wanted to bill a buyer without requiring they log into PayPal each time you would need to use billing agreements (reference transactions) through Express Checkout. If you set up a billing agreement with a buyer you can charge a previously successful sale to bill them again for a different amount.
You cannot do what you want with Express Checkout, especially since nobody will ever enter the paypal details on your website (that is the entire point of paypal).
You can use either preapproved payments (buyers preappove payments being taken out of their account up to a certain ceiling), or reference transactions (you reference a new transaction to an older transaction. PayPal will then use the billing details of this earlier transaction to bill the user).
Preapproved payments is part of Adaptive Payments. Documentation is at https://developer.paypal.com/webapps/developer/docs/classic/adaptive-payments/integration-guide/APIntro/
You can find more details about Reference Transactions at https://cms.paypal.com/uk/cgi-bin/?cmd=_render-content&content_ID=developer/e_howto_api_ECReferenceTxns
Note: Reference Transactions needs to be enabled on your account. This API call is not open to everyone due to the potential for abuse, so you may want to look into whether you're eligible for it before you start working on a full integation with it.
You can find more info here :https://www.paypal-community.com/t5/Merchant-services-Archive/Does-Paypal-have-a-quot-Token-Payments-quot-concept/td-p/325794
Also google "token payments" as that is what you need and most payment gateways usually support them.

PHP: PayPal Integration

im building a site where 2 user groups exist: sellers and buyers. The buyers buy stuff and should pay to the sellers via PayPal.
So, its not a kind of a web shop where users are paying directly to me ( as a website owner/online shop), BUT TO THE OTHER USERS (sellers). So i need to forward a PayPal transaction from one user on my site (buyer) to the other one (seller).
I read some PayPal API Descriptions, but its assumed there that i want to process the PayPal Payments to my PayPal account, what's not my case.
An idea would be that sellers pay to me, and i then pay to buyers, but that's not what i want to do.
So , what I want is: the buyer should process the PayPal payment directly to the seller's PayPal account, and i should then receive the payment confirmation and inform the seller about it.
Does anyone have an idea, expirience or suggestion with this stuff? Thanks in advance!
You have a lot of options for how you can handle that.
One, you could use the Express Checkout API to build the checkout system, and you'd use the Permissions API (optional) so that users can easily grant your application permissions to make API calls on their behalf. Note that users could also do this manually through their PayPal profile until you get the Permissions part integrated.
To get your payments, you could have your users create a preapproval profile using the Preapproval API. This will allow you to submit payments on their behalf automatically at any time. As such, you could use the preapproval key within Pay calls directly in the checkout flow or within IPN (which is what I would recommend) to submit payments to yourself from the user's account.
Another option is to use a parallel payment within Express Checkout. This would handle splitting the payment for you automatically between the seller and yourself, but the buyer would see that split during checkout.
Another option would be to use the Pay API for the checkout which would allow you to create a chained payment. This is the same as a parallel payment except that it hides the split from the buyer, and you could actually delay the payment to secondary receivers if you need to for any reason.
Hope that helps.
if you have a buy now button or similar, use the sellers' email address as below
<input type="hidden" name="business" value="sellers#email.com">
and it will pay the user with that email address. If that's not their paypal address, it will prompt them to either sign up for paypal to receive or add it to a current account.
Then use PHP mail() or your CMS/Admin system to notify you when the successful payment page has been loaded after a referral back from Paypal.

Put my logo on Paypal page when my sellers sells some product from my website

I am doing paypal integration in my website in a section called stores where an user can sell his products from my store. And i am storing the paypal accounts of my sellers to pay him directly when customer purchase something from his store in my website. Is it possible to put my logo on the paypal checkout page where the seller email id i'm passing will not be mine(Since each sellers will have their own Paypal Business email id)?
Yes, you can make it using PayPal Express Checkout. No need for upgrading to Pro, and paying a fixed monthly fee.
When setting up the express checkout transaction, you have a parameter that tells PayPal which images to show for branding.
https://www.paypalobjects.com/en_US/ebook/PP_APIReference/expresscheckout.html#1144280
The parameter name is called cpp-header-image which make sure it's delivered through HTTPS otherwise the browser may ask the user is he/she want to see only the securely delivered content.
There is something called "PayPal Payments Pro", which allows you to have many options over a typical PayPal account. From X.com (a great resource for learning about the Paypal API Stack), I was able to pull the following link for you (which explains what you are wanting to do)
