According to this DHL statement, the shutdown of version 1 SOAP API will occur on May 31, 2024. DHL Shipping Plugin in plenty is based on SOAP Version 3 and will not be impacted on this date. According to the Information we currently possess, It should not be changed within the next two years (further information and more specific updates from DHL will follow in the future).

The new REST API Module is already available as a beta-version in plenty. With the early switch to REST, we are giving you a longer “test phase”, as the effective switch-off of the old interface with version 3. We also reserve the right to discontinue our SOAP implementation with an appropriate lead time (a separate announcement will follow).

Further information concerning this update is available in this forum thread.

Best regards,
