node_id attribute, used to identify objects in our GraphQL API from our REST API, has just graduated from preview for GitHub dotcom and GitHub Enterprise versions 2.14 and higher. The
node_id attribute will be included in all supported REST resources that have a corresponding GraphQL object, and you can use this information to help move between the REST API and the GraphQL API. For more information, see "Migrating from REST to GraphQL" and "Using global node IDs."
Preview media type no longer needed
Now that the preview period has ended (first announced in December 2017), you no longer need to pass this custom media type. Instead, we recommend that you specify v3 as the version in the Accept header:
Please note that if you use GitHub Enterprise versions 2.11 to 2.13, you will still need to provide a custom media type in the Accept header:
Onward! Thanks again to everyone that tried out GraphQL global node IDs during the preview period. If you have any questions or feedback, please let us know on the GitHub Platform Forum.
