Learn the fundamentals of the HALO GraphQL API and how to design, develop, and implement time-saving automations
Summary
This presentation introduces the foundational concepts of GraphQL, beginning with a clear explanation of what GraphQL is and how it is implemented for the HALO Link platform. It then provides an overview of OpenID Connect (OIDC) while examining both the Client Credentials Flow and the Authorization Code Flow. The session demonstrates how OIDC authentication integrates with the HALO Link GraphQL API, including a walkthrough of obtaining an access token using the Client Credentials Flow.
Building on these fundamentals, the presentation unveils the design and development of an Automated Slide QC Process. Feature requirements are defined, including: triggering the process via the ImageCatalogedEvent when an image is cataloged into HALO Link; automatically performing an Image QC analysis to compute percent normal tissue; and updating the corresponding HALO Link task to complete or failed based on a configurable threshold. A high-level architectural overview illustrates how the Automated Slide QC workflow interacts with both GraphQL and OIDC, supported by a sequence diagram.
The session concludes with a live coding demonstration in Python, developing the Automated Slide QC Process in real time to show how the concepts, APIs, and authentication mechanisms come together in a practical implementation.
Learning Objectives
- Learn the fundamentals of GraphQL and how it is implemented in HALO Link
- Learn about OpenID Connect and how OIDC authentication works with the GraphQL API
