By December 16, 2021Blog

This year’s API Specifications Conference (ASC) organized by the OpenAPI initiative was held virtually from September 28 through 29, 2021. The conference continues to grow by leaps and bounds and is gaining the attention of people interested in API technology. It was a real thrill hearing from industry experts discussing topics such as OpenAPI Specifications, RAML, Blueprint, gRPC, OData, JSON, Schema, GraphQL, AsyncAPI and other formats. For example, the keynote presentation Leading API efforts at scale by Mandy Whaley & Yina Arenas, Microsoft, So you think you understand JSON Schema? By Ben Hutton, Postman/JSON Schema. Or AsyncAPI 2.0: Enabling the Event-Driven World by Someshekhar Banerjee, Ebay.The discussions helped attendees get acquainted with the different formats and also learn how to practically use them.
