The one-time setup must be done before you can process payments and must be done on each machine. PayPal recommends using a separate setup page for the setupUI. Include the following snippet in your setup page:.N ki rashi kya hai
To make sure that the setup has been completed on your computer prior to processing payments, call isSetupComplete. Otherwise, if it has already completed, you can continue on to your payment flow.
Note: See Object references later in this section for details on various options for the different objects in this flow. Create identity.
It tells the SDK which merchant account is receiving the payment and in which environment. Payment configuration. Even though you can process transactions with default values, the SDK allows you to customize the flow depending on your needs. Payment configuration is required for subscribing to events and customizing the payment flow. The following code snippet creates a default configuration:. Create order. In order to process payments or refundsyou need an order.
The following snippet shows how to create an order for a payment and add items to it:. Process payment. Once you have the identity, payment configuration, and order ready, you can then accept the payment. The following snippet shows how to process a sale transaction:. As part of the payment flow, the SDK will automatically prompt for any reader firmware updates that may be available.
You'll need to subscribe to the success or failure events on the Reader object to get the status of said updates:. When the reader firmware update is done successfully, the SDK will simply continue on with the payment flow without you having to action anything.
If the not now option was pressed on the reader firmware update UI, then you will need to call pendingUpdateInstall to trigger that firmware update flow and install the update. If there is a firmware update, it needs to be completed successfully before you will be able to process another transaction.
You can also call pendingUpdateInstall prior to making a payment if you'd like to proactively check for any firmware updates available. Note: saleauthorizeand refund are action calls that need to be last in the chain, as noted in the samples. Refer to the samples for more details on the usage of these payment method types.
Event handlers are functions that are subscribed to as part of the PaymentConfiguration.
These events may have arguments as mentioned below. Refer to the samples for details on how these events are implemented. When your integration is complete, check the going live page to ensure that you have everything ready for activation.
Once that is working, you can implement other customizations that are available with the SDK into your integration. Popular Search Queries.

If the status is connectedthe following authResponse parameters are included in the response:.
If a person opens your webpage but is not logged in or not logged in to Facebook, you can use the Login dialog to prompt them to log in to both.
If they are not logged into Facebook, they will first be prompted to log in, then prompted to log in to your webpage. To use your own login button, invoke the Login Dialog with a call to FB. This dialog allows you to ask for permission to access a person's data.
The scope parameter can be passed along with the FB. This optional parameter is a list of permissionsseparated by commas, that a person must confirm to give your webpage access to their data.
This example asks the person logging in if your webpage can have permission to access their public profile and email. The response, either to connect or to cancel, returns an authResponse object to the callback specified when you called FB.
This response can be detected and handled within the FB. Additionally, logging out of your webpage does not revoking permissions the person granted your webpage during login.
Revoking permissions must be done separately. Build your webpage in such a way that a person who has logged out will not see the Login dialog when they log back in.

Fetching your informationA Web developer is usually concerned with the back end or the programming aspect of creating a website or Web application and is not to be confused with a Web designer, who only deals with the aesthetics of a website or application, although many professionals have both skill sets.
Web developers are found working in many different types of organizations, from small and medium-sized businesses to large corporations.
Many also perform the job on a freelance basis. Web developers can come from different educational disciplines because Web development is one of those fields where once a programming language is learned, much of the rest of the skill set can be acquired through practice.
Although there are no formal educational requirements to be able to work as a Web developer, a lot of employers do prefer formally educated people who come from any computer related field and have Web development skills.

Simplify your data sharing, transportation and availability with XFA.In the modern development landscape, these two tools and the synchronicity between them are the driving force behind web communication and the implementation of third-party APIs. In this piece, we will attempt to create an inclusive definition of both concepts. We will give an example of each, explain how they interact with one another, and find how an API provider can effectively implement one or both of these tools to improve their offering and end developer usability.
An API is simply an interface that allows software to interact with other software. Think of an API as a Rosetta stone, a tablet by which two vastly different languages, two different instruction sets, can be translated and transferred for mutual understanding. APIs come in many shapes and sizes. The browser that a reader would likely use to peruse the Nordic APIs website uses a variety of API sets in order to convert user commands into usable functions, request data from servers, render that data into a viewable format for the user, and validate the performance of their requests.
Even something as simple as copying and pasting on a computer utilizes an API. Copying text converts a keystroke into a command, data is stored into RAM on the clipboard utilizing an API, the data is then carried from one application to another using that same API, and finally, data is rendered when pasting using yet another API. On the world wide web, the API takes on a slightly different function. Web APIs allow for interaction between disparate systems, often for specific use cases.
Ultimately, a web API is simply a set of instructions, just like the personal computer API, but based in the web space. Perhaps most important is the fact that APIs allow for consistency.
In the early years of programming, the computer was a wild west of commands and instructions, loosely coded and rarely documented. With the advent of modern computing, APIs have allowed for consistent coding in stable environments, allowing for replicable functions to be delivered the same every time the request is submitted with reliability and predictability. Think about putting together a model car or plane. When constructing this model, a whole kit of items is needed, including the kit pieces themselves, the tools needed to put them together, assembly instructions, and so forth.
An SDK or devkit functions in much the same way, providing a set of tools, librariesrelevant documentation, code samples, processes, and or guides that allow developers to create software applications on a specific platform.
If an API is a set of building blocks that allow for the creation of something, an SDK is a full-fledged workshopfacilitating creation far outside the scopes of what an API would allow. SDKs are the origination sources for almost every program a modern user would interact with.
From the web browser you work on all the way to the video games you play at the end of the day, many were first built with an SDK, even before an API was used to communicate with other applications. By definition, an SDK is a kit that includes instructions that allow developers to create systems and develop applications. APIs, on the other hand, are purpose-built for an express use — to allow communication between applications.
It should be no surprise then that, when an SDK is used to create an application that has to communicate to other applications, it includes an API for this functionality. Inversely, an API is used for communication, but cannot be used solely to create a brand new application.
Another way to understand this is to think in terms of houses. APIs are telephone lines, allowing for communication in and out of the house. The SDK is the house itself and all of its contents.
Because this suite provides tools for both active users and developers, it includes both an API and an SDK, each with different functionalities and use cases. Used internally and with third-party application providers, the Facebook API allows for communication across the wide Facebook social platform, and utilizes the social connections and profile information data points of every Facebook user to conduct application functions.
Page, photo, event, friend, and group data is collected and collated and used to form meaningful and useful connections that increase the extensibility of the service. The API also allows for the limiting of this data sharing on a per-user basis, allowing for users to limit their profile content and the use thereof.
This integrated security allows for extensive use of multiple data points and resources while still maintaining high privacy and security levels.A web developer is a programmer who specializes in, or is specifically engaged in, the development of World Wide Web applications using a client—server model.
NET C or Java in the server, and http for communications between client and server. A web content management system is often used to develop and maintain web applications.
Web developers are found working in various types of organizations, including large corporations and governmentssmall and medium-sized companiesor alone as freelancers.
Some web developers work for one organization as a permanent full-time employee, while others may work as independent consultantsor as contractors for an agency or at home personal use. Web developers typically handle both server-side and front-end logic. This usually involves implementing all the visual elements that users see and use in the web applications or use, as well as all the web services that are necessary to power the usage of their developing work.
Salaries vary depending on the type of development work, location, and level of seniority. Modern web applications often contain three or more tiersand depending on the size of the team a developer works on, he or she may specialize in one or more of these tiers - or may take a more interdisciplinary role. NETNode. Meanwhile, the other developer might focus on the interaction between server-side frameworks, the webserverand a database system. There are no formal educational or licensure requirements to become a web developer.
