This is what I've currently got and it creates a new Confluence page. It doesn't update it. Also it posts it in the root space, `TST`, but I want it to be in `TST/space1/subsection2/updateThisPage`.

```
curl -v -u admin:admin -X POST -H Content-Type: application/json -d  "{\"id\":\"123456\",\"type\":\"page\",\"title\":\"new page\",\"space\":{\"key\":\"TST\",\"title\":\"updateThisPage\"},\"body\":{\"storage\":{\"value\":\"<p>This is the updated text for the new page</p>\",\"representation\":\"storage\"}},\"version\":{\"number\":3}}" http://localhost:8090/rest/api/content?spaceKey=TST&title=updateThisPage

```

This is the error message I get 

```
{"statusCode":400,"message":"A page with this title already exists: A page already exists with the title new page in the space with key TST"}

```

Would it be a permissions error? I know I do not have access to delete.
