This seems to work when hitting the wiki/rest/api/content/
endpoint
{
"title": "Test Page from API editor v2",
"type": "page",
"space": {
"key": "TS1"
},
"status": "current",
"ancestors": [
{
"id": "1239286918"
}
],
"body": {
"storage": {
"value": "Test content",
"representation": "storage"
}
},
"metadata": {
"properties":{
"editor": {
"value": "v2"
}
}
}
}
