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

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.

The IAP server-side module in php

My hired service does not allow JAVA application to run at the service provider. Therefore, IAP server module must be implemented in php.
I wrote php code. I think I can implement it. But if someone has already done it, I would save some development time.
Please inform me is there public IAP server-side module PHP implementation?
IAP servers have a huge range of complexity depending on the needs of your business. The simplest implementation would be just a receipt validator, and there are a handful open-source examples of this on Github (https://github.com/aporat/store-receipt-validator)
Since you mentioned saving development time, there are services such as RevenueCat that manage a complete IAP server for you.

How to register an application?

Using the Outlook REST API, I want to make a browser extension (To-Do). I need graph api and the REST Task API. I make this application only for myself (maybe I will add it on github). Tell me, should I register an account as a commercial developer? Do I need to confirm for this application? Is it free? Where can I register the application? thank
I suggest you go through the Quick Start documentation, which will help you pick the appropriate platform and walk you through registering your Graph application. Also join the Office 365 Developer Program which will give you a free Office 365 developer subscription that you can use.

ASP.NET WEB API Authorization or User based Licensing

Have done a lot of search and reading over the WEB but could not come to any conclusion yet.
We are planning to develop a list of API's (planning to use ASP.NET WEB API). One of the business goals is to package the API and selling/licensing the Packages/API to end users.
Some thoughts that came to consideration:
Using Authorisation Filters to do check against database, if the user requesting the API has access to it or not. Not very sure of the implementation details yet even on this approach.
Are there any better suggestions or ideas or any open source libraries that we can go with?
What are the possible recommendation or best practices to achieve this.
Thanks in advance.
Please take a look at the following links. Hopefully, they help.

does osCommerce have an API?

We work on a lot of integration projects and a customer has a legacy ecommerce site and have asked us to integrate product information, orders and inventory with another platform.
Does osCommerce have an API that can be used for this, or will we need to build our own web services based wrapper for the dB?
No, not that I know of.
I think you'd need to find one online (never heard of one) or build one yourself.

Is there a Web Service community with a large and variety pool of services provided to consume?

Please specify and rate your experience if you know any. Thanks! =]
No there wouldn't be anything like that. In my experience each web service is designed for a very specific purpose, and would not have application outside it's original product. Also, a lot of web services are locked down to prevent unauthorized access. I am not aware of any collection of web services being made available from a single place. Would be curious to check it out if there is one, though.
