The Apic Discovery Test repo allows you to test the discovery action from here. This is an example repo from where the API documents can be sent to the API connect manager using the discovery action and where they can be promoted as required to be managed by Apiconnect through their entire lifecycle.

See discover-api.yml and send-to-discovery.yml

The file discover-api.yml has an example of sending the API documents in different ways to the host d-j02.apiconnect.dev.automation.ibm.com to the provider organisation name niraimathi when the workflow file or any one of the mentioned API file content changes.

The job check_changes_job checks for the changes in the workflow file or mentioned API document and the job run-discovery sends the documents mentioned.
The run-discovery job uses the apic-discovery-action repo main branch in the ibm-apiconnect organization

• uses: ibm-apiconnect/apic-discovery-action@main
  with the parameters supplied

with:
  api_host: ${{ env.API_HOST }}
  provider_org: ${{ env.PROVIDER_ORG }}
  api_key: ${{ secrets.apicApikey }}
  if: env.API_FILES
  api_files: ${{ env.API_FILES }}
  else if: env.API_FOLDERS
  api_folders: ${{ env.API_FOLDERS }}
  resync_check: ${{ needs.check_changes_job.outputs.action_changed && true || false }}

The file send-to-discovery.yml is another example of sending API documents with the extra variable git_diff which sends the git diff files between the current and previous commit. And the discovery action will send the api_files or api_folders to the server when there is a change in the files.

The content can be modified according to the test requirement for sending the APIs
