IBM Watson provides a set of industry leading AI services for conversation, natural language processing and other purposes. Since 2019, IBM has provided an ABAP SDK for IBM Watson to allow ABAP programmers accessing the IBM Watson services in a very convenient way. On June 29th, 2021, IBM has released version 1.0.0 of the SDK. Its main purpose is to adopt the changes that came with OpenAPI specifications version 3. Along the lines, some minor bugs were fixed and new methods were exploited.
