How can i capture more then autorized amount - paypal

On the PayPal developer site they state it is possible to capture 75 US Dollar or 15% percent more than the original authorized amount of a payment. I am currently using the order API because I can't seem to figure out how to create a Payment from the payment API. My question is the following: how can I capture a different amount then the authorized amount(order API). In the capture section of the Order API I can't give up a new amount. I tried to patch the order first but after the amount was authorized the status of the order is COMPLETED, so the value couldn't be updated.
I think the reason I don't understand how to do it is because I don't know the difference between Order and Payment API. I would like to use the payment API but I can not find an PayPal API to create a payment.

Use the order API with "intent":"authorize". The completed order will have a payment authorization object in the response.
Use the payment API to capture the authorization object for the desired amount, https://developer.paypal.com/docs/api/payments/v2/#authorizations_capture

CyberSource: Retrieve Capture Token from PayPal Transaction Details

I'm trying to retrieve the capture request token from past PayPal transactions as I need that for refunding customers. We don't have that info anywhere on our systems anymore because, just don't even ask. It looks kind of like this:
AxjrrwSTQDiO3h+N6P5RABJPE8jCJjo7f4OxZX/x/FO5LcGBSKHWXfwtSx+j1ncoSt3SABJtkGk=
Is it possible to get that?
I looked at PayPal's Transaction Search API here and nothing in the response says that field exists:
https://developer.paypal.com/docs/api/transaction-search/v1/
I have also checked the built-in reports on PayPal but they don't give us that either.
Furthermore, I have tried the REST API with CyberSource and that doesn't provide the Token either:
https://developer.cybersource.com/api-reference-assets/index.html#transaction-details
I have the PayPal Generated Transaction ID, the dates, our reference numbers, etc. All I need is that Capture Request Token. I will then be able to refund customers using CyberSource.
Any help or ideas would be most appreciated.
That's a CyberSource token, so you won't find it anywhere within PayPal.
The PayPal REST API itself (no CyberSource) doesn't require it for refunds, only the transaction ID: https://developer.paypal.com/docs/api/payments/v2/#captures_refund

Which PayPal API for variable billing

I have a site that bills variable monthly amounts based on the subscriber's usage (typically $3 to $60). Currently, the 200 or so subscribers set up a monthly PP subscription that may or may not match their usage. I would probably use IPN to collect that info, but currently do it by hand.
I would like to use an API to request and receive the exact monthly amount. Which API? I have read elsewhere that Adaptive Payments may be the one to use, but is that appropriate/accessible to my business size?
Additionally, where would I post a request for a programmer for such?
You would need to utilize Reference Transactions for that.
Basically, you setup a billing agreement with the user an then you can use the Billing Agreement ID that you get back with the DoReferenceTransaction API any time in the future to process any amount necessary without further approval.
So you'll need to create your own system to automatically process payments on a daily basis as necessary, but this method will allow you to handle variable amounts.
If you're using Payments Pro you can do the same thing, but you don't do a "billing agreement". What you can do instead is run a $0 authorization, and then you would use the transaction ID you get back from that in the DoReferenceTransaction request instead of a Billing Agreement ID.

How to test a PayPal capture API call with Sandbox

I have setup PayPal Sandbox test accounts, a Personal (buyer) and a Business (merchant).
I'd like to test a PayPal 'DoCapture' API Operation. The problem I'm encountering is that I need an AuthorizationID and don't know how to obtain it. If i run the 'DoExpressCheckoutPayment' API call, I do not get an AuthorizationID returned, using the merchant API credentials, though I do get an 'ACK' of success. Do I need to be using the buyer credentials with the 'DoExpressCheckOutPayment' call? I don't see the API credentials in the PayPal Sandbox profile for the Personal account.
Express Checkout example with authorization and capturing you can find here.
Short answer - according with DoCapture documentation
AuthorizationID ... This is the transaction ID returned from DoExpressCheckoutPayment...
According with DoExpressCheckout documentation you need field from response, attention, PaymentInfo#TransactionId
... this value is your AuthorizationID for use with the Authorization & Capture APIs.
This is what you need to do to implement the capture API.
Create Payment: set intent as authorize in its request to get payment Id
Show Payment Details: to get approval_url. The customer will use this URL to pay for the order.
Execute approved PayPal payment: Use this API after customer successfully pays for the order. This API returns authorization-id along with capture link.
Use Capture API: use the URL obtained from step 3 to capture.
Use this link and check payments API.

Paypal: Is there a way to check a cart right before a user pays?

Is there any way currently for Paypal's API to send my site an authorization request before completing a user's payment?
I think the answer here would be that there is no way to do this, but one can set "authorization" as a cart parameter instead of "sale". This still leaves the question of how to complete the authorization in the callback.
May be this would clarify your doubt up to a certain extent.
Authorization & Capture starts when your buyer authorizes a payment amount during checkout.
For example, you can use the PayPal Express Checkout API with the PAYMENTACTION element set to Authorization or Order.
After your buyer completes checkout, you can then use the payment’s transaction ID with Authorization & Capture APIs. You can:
Capture either a partial amount or the full authorization amount.
Authorize a higher amount, up to 115% of the originally authorized amount (not to exceed an increase of $75 USD).
Void a previous authorization.

Express Checkout is what you want, but there's better documentation available.
Basically, what you're after is Authorization and Capture. When you create your Express Checkout API requests you'll set the PAYMENTACTION to Authorization. Then, when you're ready to process the payment you call DoCapture and pass in the transaction ID you get back from Express Checkout.
No money is processed until the DoCapture call is processed. If you don't end up needing to process it you can simply do nothing, but that would strand the authorization on the user's account for the default period of time depending on their bank. Usually 30 days.
It's a better practice to call DoVoid at that point, which would cancel the authorization and release those funds back to the user's account immediately.
If you want to do the same thing with credit cards directly you can use Payments Pro. The process is almost identical, except there are actually fewer calls involved.
If you're using PHP I would recommend taking a look at my PHP class library for PayPal. It'll make all of this very simple for you, and I can provide 30 min of free training to help you get going if you want, too.
