Header update needed as Offer API v11 exits beta

On January 19th at 12:00, the Offer API v11 will move out of beta and the Offer v11 version will go live. As part of this change, the required request header will be updated.

The current header (Content type- and Accept header):

application/vnd.retailer.v11-beta+json

This will change to (Content type- and Accept header):

application/vnd.retailer.v11+json

If you are currently using the v11 beta, please make sure to remove -beta from the header by January 19th at 12:00 to ensure your integration continues to work as expected.

Update

At 12:00 (Dutch time), we expect a short downtime of approximately 30 minutes. During this period, the offer v11 beta endpoints will be unavailable.
