While the McMaster community has access to H5P at eCampus Ontario, McMaster’s H5P license is separate and our own instance of the tool within Avenue to Learn. You can access McMaster’s H5P instance either through the Avenue to Learn integration or access it using your Mac ID at https://mac.h5p.com.
At the moment there is no link or communication between the two. If you have content in eCampus Ontario’s H5P that you would like to use in Avenue to Learn’s H5P instance, you will need to export the content from eCampus and import it into McMaster’s H5P instance.
