Introduction

Web services have revolutionized the way applications and platforms communicate and exchange data. With their ability to transcend platform and application boundaries, web services provide numerous advantages that have made them an integral part of modern technology.

Advantages of Web Services

Web services enable communication between any third-party application by using the Simple Object Access Protocol (SOAP) over HTTP.
In addition to including the endpoints for the send request, they offer a uniform set of rules for communication. For Web services like WCF, we don’t require a lot of configuration.
WEB Services support data exchange between different platforms and different applications.

Web Services can be used as web page requests and help us to receive data.
They support faster communication.
They support the highest priority of interoperability.
By using Web services, applications can easily communicate and exchange data among themselves.

Disadvantages of Web Services

While web services offer numerous advantages, they are not without their drawbacks. It’s important to consider these limitations when evaluating the suitability of web services for specific applications

The request for Web services is larger than that encoded with the binary protocol. It does matter when there are low-speed connections or busy connections.
Web Services do not have any other way to discover the service.
It uses XML, which needs to be processed in order to be read. It supports many standards, that should be followed while creating an application.

By considering these limitations alongside the benefits, developers and businesses can make informed decisions about when and how to leverage web services effectively, striking a balance between functionality, performance, and compatibility.

A subset of XML called Web Services Description Language (WSDL) is used to transmit XML communications. The behaviour of a web service is described using the WSDL. An XML-based interface supports it.

E.g.

The above example is a sample of the WSDL.

The address element contains the endpoint of the client.

We can view the WSDL directly on the browser window, as mentioned below.

http://domain.com/webservices?wsdl

How to add a web service using WSDL?

For Adding Web Service in the project, we have to use the following steps.

1) Right-click the project in which you want to add the service and click on “add” option.

2) Next, select "Service Reference" from the following dialogue box.

3) A new dialog boxwill open after clicking on the “add service reference: option.

In the above example, the address will contain a WSDL path. It may be from the local system or any online URL. After clicking on the “ok”, Button, the service gets added to the project.

For security, we can use an SSL certificate at both the ends. It is an asynchronous request and response while calling the SAP endpoints. The SAP gateway port should always be open while sending the request and receiving the response.

We can call endpoints using the following sample code.

If we are using an old version of the dot net framework, we have to use the following code for sending requests to SAP gateway:

A Developer’s Tale: Using Microsoft technologies to integrate Myzone device with Genavix application

meta_prasad — Fri, 20 Nov 2020 12:51:37 +0000

It is no secret that digital technology is slowly shaping the future of the healthcare industry. The use of fitness tracking devices has grown rapidly, the philosophy being ‘that which gets measured can be improved’. The MetaSys team has worked on integrating tracking devices with Fitness and Nutrition Applications. This article describes one such achievement, namely integration of Myzone into our clients’ application.

Our client: Genavix is a venture in the preventive health care services industry. It offers members comprehensive health and fitness solutions to reduce health risks and improve wellness. They provide various fitness and nutrition plans helping associates follow a healthy lifestyle.

About Myzone: Myzone is an innovative wearable heart rate based system. It uses wireless and cloud technology to monitor physical activity. Myzone allows the user to view their fitness efforts live on their phone, such as how many calories they are burning. Users are also able to make connections and compete with other individuals in the network. Based on their fitness efforts, users are awarded MEPs (Myzone Effort Points), which they can use to challenge others on the platform.

We at MetaSys were given the task of integrating the Myzone system with our client’s application. Our solution used the fact that each Myzone device has a unique belt number, which is registered with a particular wellness facility. Users are able to submit their Myzone belt number, after which a unique ID is assigned to their profile. The client system can then track all Myzone activities.

One of the challenges we faced in the integration, was that the data obtained from the Myzone API is only available for the last three months. As a long term health app, our client tracks fitness for a much longer duration. To resolve this issue, we decided to import the data every night by creating a task scheduler, which imports data from the Myzone API into the application SQL tables.

Each wellness facility with registered Myzone belts has a unique API key. Using this API key and Myzone Cloudbase API – 2.0.3, a web request API call is made which retrieves Myzone API data of each user in the previous three months. The data is received in JSON (JavaScript Object Notation), is then interpreted in Asp.net and imported into the application SQL tables. The imported data is used to build a user fitness diary that integrates the Myzone data with data that has been manually entered in the application by the user. The detailed tracking of fitness, such as tracking calories is used to help every user, achieve their daily health and fitness goals.
