SAP API :Simplify Business Processes with Seamless Integration

Application Programming Interfaces, also called SAP API have a significant function in how we interact with technology in the present. Application Programming Interface or API is a user interface that is provided by an application to interact with other software. APIs describe the ways software programs are able to exchange data with each other, regardless of whether they are designed and operated by different companies.

This Digitalizing process in businesses requires integration with non-SAP systems.SAP standard interfaces provide the possibility for connecting the external system to SAP Such as BAPIs, RFCs IDOCs.etc. SAP interfaces permit all other software and solutions to share information with the SAP system.

SAP now provides a range of libraries (connectors) for various programming languages (VB, Java) that allow custom systems to connect to SAP and perform various tasks. These tools are still used in a variety of older custom applications and systems.

What are the advantages of using sap api?

  • There is no development or implementation cost.
  • Near real-time data transfer.
  • 100% fully automated machine-to machine data exchange decreases risk of errors.
  • Stability and security are improved.

What are the various SAP API types?

There are different kinds of APIs are available in the market here are listed of APIs most commonly use

  • Odata API


OData is a protocol based on REST for updating and querying data. It is based on technology such as HTTP ATOM/XML, ATOM/XML & JSON. It is more adaptable than other web services based on REST and offers a consistent method of describing the information and data model to facilitate interoperability among data sources, applications, services, and clients.OData that is well-known in the SAP world, is a REST API.


The development of REST APIs is done in a certain way. They’re based on the HTTP protocol, which lets you use URIs to send and receive JSON and XML data (uniform resource identifier). The use of JSON-based REST APIs is common.

SOAP is Simple Object Access Protocol – is perhaps the most well-known model of both.SOAP is heavily based on XML and, when combined with schemas, creates a highly structured messaging framework.SOAP is the abbreviation for Simple Object Access Protocol. It’s a protocol for exchanging data in a distributed and distributed system. SOAP works with any protocol that uses an application layer like HTTP, SMTP, TCP, or UDP.

SAP API Management

Designing APIs using the API Portal and offering APIs through the Developer Portal are the two key areas of SAP API Management.

The API Builder can use so-called “API proxies” within the API Portal to abstract an existing API or SOAP WebService (through the façade pattern). The API proxy should be the sole way to access the actual API implementation, hiding internal data and providing certain characteristics that would otherwise have to be programmed in the API itself, such as security, traffic management, and data transformation.

A web service API is a common infrastructure for interfacing with an enterprise service, but its requirements and how to create an API are not very consistent. In the past, this was mainly due to differences between the API developer tools and the design of the actual API implementation.

In the Cloud solution, this is no longer the case. The infrastructure behind the platform has been designed with exactly this type of situation in mind. The SOAP web service APIs will be exposed in the façade pattern and by using an API proxy, such as Apache JMeter, can be modeled.

The following sample shows an API example with SOAP WebService and some payloads:


POST /api/orders POST /api/orders HTTP/1.1 Host:

Design APIs Through the API Portal

The portal allows you to design your API in a simple and intuitive manner. It provides high-level programming constructs, a powerful keyword-based DSL so that you can easily build an API that conforms to your design principles and the architecture of your platform.

The API Builder can serve as a UI-based mockup and is always up-to-date with the latest technical details. It allows you to start new projects, upload mockups, and choose the right interfaces to manage your API.

Before you can start building your API, you need to configure the Platform ID, select a Platform and apply all components in your API. Your Account, Integration Services, and SOAP interface specifications are the most important parts of the API.

Provide APIs Through the Developer Portal

By using the Developer Portal, you are no longer limited to designing the API from scratch. The portal gives you access to the full SAP-API product suite, providing complete access to all types of functionality required for any business process. And unlike the API Builder, it is possible to integrate virtually all of your own business logic inside your own tools, without ever leaving the portal.

Create APIs From Data Structures

Implementing the change in the way you receive data in your SAP Ariba applications is actually pretty straightforward. There are only 2 models that you can interact with to transform this data, namely Abstract Data Type (ADT) and Data Transformation. The simplest example would be transforming the customer address structure to a database table or column.

An overview of the Developer Portal

Access to the API Manager is required to monitor and control each API in your production environment.

Data can be discovered using the Data Discovery Web Service, which exposes a REST API for querying the data store through a set of RESTful principles. (Exchange provider XM1 provides X-Real-IP from a SIP connection, thus it’s also known as X-Real-IP-to-IP-Address)

Data Transformation, implemented through a Data Transformation Protocol, exposes an API for specifying transformations, can provide settings to enable, limit and enable only transformation based on certain rules.

Data Manipulation, such as the addition of new fields, subtraction of existing fields or the creation of new records, can also be achieved with the available Data Manipulation APIs.

Final Thoughts.

Both SAP API Management and the SAP HANA Management Suite are exceptional choices in the space of modern business infrastructure. They are not only the first and only technologies that enable a single administrator to design, operate, and monitor an enterprise-wide SAP system, but they are also fantastic tools that offer a lot more. Asynchronous programming is now possible, and all of the OOP goodness that Object-Oriented Programming brings to the table can now be leveraged to build APIs.

The new HANA Development Solutions can be used both for the development and for the administration of a database, and the cloud-centric platform allows a user to optimize workflows through its many capabilities.


SAP API Management is a framework that simplifies the design, deployment, and management of APIs, connecting SAP and non-SAP applications. It offers tools like API Portal for meticulous API design and Developer Portal for developers. The strategic use of SAP APIs can unlock new business models, accelerate digital transformation, and create new customer and partner engagement channels. It’s a step towards future-proofing enterprises.
