Web APIs have become the connective fabric of existing businesses and innovative business models. Balancing the need for connectivity and collaboration with the inherent dependency in API-oriented settings is one of the biggest challenges in this new API-based landscape. Only part of the problems and solutions in this space are technological in nature, as there also is a large organizational and cultural aspect to this: The question of how to change structures so that organizations can move as quickly as possible in order to adapt to new challenges, and take advantage of new opportunities.

Digital Transformation

It may be hard to pin down the exact meaning of “Digital Transformation”, but it is what many organizations are experiencing and trying to master these days. And whatever exactly organizations are faced with, at the heart it is about data-driven processes and decisions, and this data is increasingly transported through a constantly reconfiguring chain and web of APIs. Understanding the best way how to design and operate for this inevitable future is the underlying theme of the workshop.

As APIs become the connective tissue of modern enterprises, they also become the foundational building block which can be used to learn more about how an organization is structured, how information is passed around, and how this changes over time. Thus, APIs not only transport data, their usage also become the source for more data, which allows a new crop of metrics and decision processes to replace older ways of making decisions.


Issues include provider-side topics such as design and runtime aspects of services, as well as consumer-side topics such as how to combine them and use them in a fault-tolerant way. Specific issues include, but are not limited to:

  • API Design
  • API Documentation
  • Microservices
  • Representational State Transfer (REST)
  • Serverless Architectures
  • Design Time Service Discovery
  • Runtime Service Discovery
  • Management of API Landscapes
  • Choreography/Orchestration of Web APIs
  • Security Issues and Trust Models
  • API Monitoring
  • API Metrics
  • Scalability Issues
  • Balancing Service Evolution and Stability
  • Improving Resilience in an API World
  • Setting up Organizations for API Focus
  • API Stories from the Trenches
  • Operational Aspects of APIs

Submission Instructions

This year, WS-REST will offer two tracks for submission: Research and Industry. While the research track continues the WS-REST tradition of being a forum for quality peer-reviewed research papers, the industry track focuses on attracting submissions from practitioners about their experiences and results.

Research Track

We solicit full papers of up to 6 pages, and short papers of up to 3 pages describing work-in-progress or results. Authors are invited to submit original, unpublished research that is not currently under consideration for publication in any other forum.

Workshop submissions will be evaluated based on the quality of the work, originality, match to the workshop themes, technical merit, and their potential to inspire interesting discussions. The review process is single-blind, so please provide your name and affiliation.

Please use the ACM Proceedings Templates when writing your papers. Your submission must be in PDF format, and has to be submitted via EasyChair at

Accepted workshop papers will be published in the WWW companion proceedings and will be available in the ACM Digital Library. These paper may be regarded as prior publications by other conferences or journals.

For inclusion in the proceedings, at least one author of the accepted paper has to register for the workshop (please see conference page for details) and present the paper.

Industry Track

As a new part of the WS-REST event, this year we are hosting an Industry Track to collect field-tested examples of working implementations, observations, and recommendations in the Web Services, REST, and Web API fields. Industry Track submissions can be as short as a one-page extended abstract or as long as a three-page position paper. This is a great opportunity for companies and teams who would not normally submit a paper for peer-review to contribute to the growing and vital field of Web APIs alongside academic-level colleagues.

The API and Web Services space is changing quickly and this year’s Industry track is an opportunity for authors to submit talks that demonstrate original and outstanding industry practices in the REST, Web Services, and Web API space. Submissions in the industry track should focus on applied examples, original observations, and use-case analysis.

The industry track only requires extended abstracts for submission. Please submit around 500 words explaining the topic of your planned presentation, and how it benefits the program and the audience of WS-REST 2018. Please submit your proposal via EasyChair at
