SAP StreamWork is an online collaborative environment that to helps people make better decisions based on shared data, and feedback from colleagues. StreamWork exposes a lot of its functionality to the outside world via REST APIs. This is great, as all environments which support sending HTTP requests can integrate with StreamWork. By doing so, you can easily convert you application into a collaborative application.
So far so good. NetWeaver and ABAP provide some class libraries which allow you to send and receive HTTP requests. So it should be possible to integrate an ABAP system with SAP StreamWork. However, when I talk to ABAP developers they very often tell me that a) they do know ABAP very well but b) they have only very basic knowledge in HTTP and therefore do struggle in making REST calls out of their ABAP coding. They would be very interested in sample coding and a step by step instruction on what they need to do. And – very important – this coding and the sample should also help them in understanding in what is required to master OAuth (which is used by SAP StreamWork REST API Authentication, Authorization, and OAuth).
- Integration of SAP StreamWork with the ABAP world
This is the first article you should read. It fully covers the Oauth process and shows you how to read and write date from and to SAP StreamWork.
- Using HMAC-SHA1 Signatures (ABAP)
For added security, Oauth also supports HMAC-SHA1 signatures. If you have never dealt with signatures in ABAP you can get started reading this article.
- Building RSA-SHA1 Oauth Signatures in ABAP
The most secure OAuth signature method is RSA-SHA1 as your application does not have to locally store neither the Oauth consumer secret nor the access token secret. This article will tell you how to setup NetWeaver to be able to use this signature method and will provide the ABAP coding which actually builds an RSA-SHA1 signature.
During TechEd 2011 in Bangalore and Madrid we will have sessions which cover the integration of StreamWork out of an ABAP system. The session “PMC223 – Developing Collaborative Solutions with SAP StreamWork” will use ABAP samples to demonstrate how to integrate via the REST API with SAP StreamWork. You don’t have to be an ABAP developer to be able to understand the session. The basic concepts and steps are independent of the programming language and it should be simple to translate the ABAP coding into your language of choice.
If you want to know more about StreamWork itself you should attend “PMC113 – Collaborative Decision Making in the Enterprise with SAP StreamWork “
