As communicated via our blog and newsletter, we will be sunsetting the EZ API as of 31 December 2021.
All repositories that used the EZ API will need to transition to the the DataCite REST API. This must happen before 31 December 2021.
The webinar sunsetting of the EZ API provides more information for those making the transition.
Do not hesitate to contact us with any questions!
Kind regards,
The DataCite Team
