In the new 2023R2 release of SAGE X3 we can find information about the new GRAPHQL capabilities for customation or extensability, like:
Add-on packages for Sage X3 API dictionary
You can create new add-on packages in the dictionary for customizing and extending the Sage X3 GraphQL API.
Packages help you manage your extensions securely and can be associated with activity codes. Packages can be extensions of other packages.
Declare scripts through the Sage X3 API dictionary
To run a wide range of operations, you can declare Sage X3 scripts, or subprograms, as GraphQL operations attached to a GraphQL entity through the Sage X3 API dictionary.
See the online help and training resources for more details on the Sage X3 GraphQL API.
Automatic generation of GraphQL node definitions
GraphQL API schemas are described in the Sage X3 metadata dictionary. You can easily extend standard APIs, including customizations, and create new queries and operations.
The API menu contains all the links needed to view or extend the Sage X3 GraphQL APIs: packages, data models, node bindings, binding dictionary, and operations.
After updating SAGE X3 we can find the new menu options for Development API, but no documentation from there, through the normal online help.
The only existing information is the release notes, but no help or how to, or even what's new we can find!
