What do I need to use PayPal API? - e-commerce

I a real noob when it comes to developing applications for PayPal. But, I have a client who needs me to build integration to paypal from his asp.net MVC website.
I am not sure where to start looking for answers on how to do this. I don't believe that my client is using Paypal Pro.
Can I use PayPal's API without a PayPal Pro account?

I think that you can get started here - https://merchant.paypal.com/cgi-bin/marketingweb?cmd=_render-content&content_ID=merchant/wp_standard

I need to integrate Square Reader device to my c# .Net WPF application to send Request & verify payment which is better way?

I have created a WPF application and integrate checkout-api successfully for payment via payment-url.
Now I want to integrate Square Reader device so can access card payment also at same application. Please guide, suggest a proper way to integrate it.
Any way to send payment request from WPF application to SQUARE READER? Now this is my current requirement. If the terminal API works for it also?
At this time the only way to take in person payments using a web application is with our Terminal API. If this is a mobile app you can use either Reader SDK or Point of Sale API.

How to integrate Sagepay iOS SDK

According to my application requirement, I need to integrate the Sagepay ios SDK, but on the Sagepay website, they don't provide any official document or flow also.
I try and get some code in the objective-c mode in here
https://github.com/ColorsSoftwarePvtLtd/SagePay-iOS
Please refer to me any SDK example codes in Swift or already existing links.
That looks like a third party project I reckon that's not an official SagePay supported SDK.
If app integration is extremely important to you, don't use SagePay and instead use modern providers like Stripe/Braintree/Adyen who generally provide SDKs and have better documentation / examples.
The support for mobile payments from SagePay is painful. We asked them for a ApplePay / GooglePay integration back in 2017 and they said then that they "are working on it". We've since gone with a different provider for those types of payments, and we're quite glad we did otherwise we'd still be waiting 2.5 years later.
At the moment for classic card payments we submit payment details to SagePay and then go to a WebView for 3-D Secure, which we've had to manage in our apps. There is unfortunately no nice SDK to use. For iOS there is this https://github.com/brightec/3DSecureView which helps somewhat with that.
HTH.

Shopify App development

I am a Joomla and WordPress developer. Now I want to learn shopify store. I am planning to develop an app to extend the shop functionality and seeing that app on market store(Like WordPress market store).
Till now I couldn't understand how I can develop my own custom app. No documentation was found with code examples. Can any one help ?
The first thing you must be familiar with is OAuth (https://es.wikipedia.org/wiki/OAuth) it is important to understand the API calls to shopify endpoints, the second thing you must know is about RESTFul, specifically the Shopify's RESTFul API (https://help.shopify.com/api/reference), knowing these points, you will be able to develope any app to extend shopify's functionality. Hope this help.

Integrating First Data (previously YourPay and LinkPoint) payment gateway with custom ASP booking system

I’m trying to integrate a simple booking system (developed in ASP) with this payment gateway: https://www.firstdata.com/
My site is hosted on a shared server and I was hoping to pass the transaction details to firstdata and have all the secure data entered and processed on their system (as in a Form Purchase token type model).
However, I'm having trouble ascertaining whether that's possible on Firstdata, the documentation is complicated and I'm not getting much response from their technical support. Ideally I'd like a test store integration example, but I can't find this on their site.
Does anyone have any experience of integrating this payment gateway using ASP, and if so any help they can offer?
Many thanks,
Lucy
FirstData is the worst for support and integration.
I have experience w/ integrating them w/ perl, so that probably doesn't help much, sorry. But just letting you know its basically trial and error, there tech support is of no help.
I have done the LinkPoint and YourPay gateways. Both required a COM object, so a DLL must be installed on the server. Is your host willing to install that DLL and incur a possible reboot for your site, or do they already have it installed?
If they have it installed, there will be sample .asp integration examples from FirstData, but you have to sign up for a developer account. Once you get their example and if you have any further questions on how to do it, please update your question here and we will work through it.
