Steps
Discover the cardholders href from GET /api as above
POST a cardholder object requiring at minimum a division href plus a first or last name
Embed access group membership directly in the same POST body as an accessGroups array, e.g. accessGroups: [{accessGroup: {href}, from: date}]
Read the Location header on the 201 Created response to get the new cardholder's href for later updates
To later remove a membership, DELETE /api/cardholders/{id}/access_groups/{membership_id} or PATCH the cardholder with a remove array
Known gotchas
Access groups, cards, competencies, roles and operator groups are all embedded sub-resources of the same cardholder POST — there is no separate 'assign access group' create call
Division is effectively required; without the correct division href the create fails privilege checks even if the field looks optional
One cardholder is created per POST — there is no documented bulk-create endpoint
