Cannot update webpage using python requests returning error response code 400

Question

I am trying to update an already existing page in the Atlassian confluence page through the Python requests module. I am using the requests.put() method to send the HTTP request to update my page. The page already has the title "Update Status". I am trying to enter one line as the content of the page. The page id and other information that is within the JSON payload has been copied by me directly from the rest/API/content... output of the webpage I am trying to access. Note: I am already able to access information from the webpage through python requests.get but I am not able to post information to the webpage.

The method used to access information from the webpage which works:

response = requests.get('https://confluence.ai.com/rest/api/content/525424594?expand=body.storage',
                        auth=HTTPBasicAuth('[email protected]', 'AIengineering1@ai')).json()

Below is the code I used to update the webpage that is returning error code 400.

import requests
from requests.auth import HTTPBasicAuth
import json

url = "https://confluence.ai.com/rest/api/content/525424594"
payload =  {"id":"525424594","type":"page", "title":"new page-Update Status","space":{"key":"TST"},"body":{"storage":{"value": "<p>This is the updated text for the new page</p>","representation":"storage"}}, "version":{"number":2}}

result = requests.put(url, json=payload, auth=HTTPBasicAuth('[email protected]', 'AIengineering1@ai'))
print (result.content)

result.content outputs the below status:

{"statusCode":400, "data":{"authorized":true, "valid":false, "allowedInReadOnlyMode":true, "errors can't change an existing page's space.", "args":[]}}], "successful":false}, "message":"Could not update content of type : class com.atlassian.confluence.pages.Page with id 525424594","reason": "Bad Request"} 

When I go to the link https://confluence.ai.com/rest/api/content/525424594?expand=body.storage I get the rest api content of my page as:

{"id":"525424594","type":"page","status":"current","title":"Update Status","space":{"id":152698959,"key":"AIENG","name":"Consumer Solutions (AI) ENG","type":"global","_links":{"webui":"/display/CSSFW","self":"https://confluence.ai.com/rest/api/space/AIENG"},"_expandable":{"metadata":"","icon":"","description":"","homepage":"/rest/api/content/155503904"}},"history":{"latest":true,"createdBy":{"type":"known","username":"[email protected]","userKey":"8a78e5ac71e441c5017250468bbc0259","profilePicture":{"path":"/images/icons/profilepics/default.svg","width":48,"height":48,"isDefault":true},"displayName":"[email protected]","_links":{"self":"https://confluence.ai.com/rest/api/user?key=8a78e5ac71e441c5017250468bbc0259"},"_expandable":{"status":""}},"createdDate":"2021-04-18T00:14:32.732Z","_links":{"self":"https://confluence.ai.com/rest/api/content/525424594/history"},"_expandable":{"lastUpdated":"","previousVersion":"","contributors":"","nextVersion":""}},"version":{"by":{"type":"known","username":"[email protected]","userKey":"8a78e5ac71e441c5017250468bbc0259","profilePicture":{"path":"/images/icons/profilepics/default.svg","width":48,"height":48,"isDefault":true},"displayName":"[email protected]","_links":{"self":"https://confluence.ai.com/rest/api/user?key=8a78e5ac71e441c5017250468bbc0259"},"_expandable":{"status":""}},"when":"2021-04-18T00:16:18.762Z","message":"","number":1,"minorEdit":false,"hidden":false,"_links":{"self":"https://confluence.wdc.com/rest/experimental/content/525424594/version/1"},"_expandable":{"content":"/rest/api/content/525424594"}},"extensions":{"position":"none"},"_links":{"webui":"/display/CSSFW/Update+Status","edit":"/pages/resumedraft.action?draftId=525424594&draftShareId=0984750c-3696-4918-b9ce-4358fefc26c9","tinyui":"/x/0ldRHw","collection":"/rest/api/content","base":"https://confluence.ai.com","context":"","self":"https://confluence.ai.com/rest/api/content/525424594"},"_expandable":{"container":"/rest/api/space/CSSFW","metadata":"","operations":"","children":"/rest/api/content/525424594/child","restrictions":"/rest/api/content/525424594/restriction/byOperation","ancestors":"","body":"","descendants":"/rest/api/content/525424594/descendant"}}

Above is the output I get on chrome when this page is not updated. But I want to update its content i.e its storage. I am guessing that the payload I am using right now is not in the right format. Any suggestions? Note: The link, username, and password shown here are all fictional.

If you're still stuck on this, based purely on your error message:

"errors can't change an existing page's space."

I would double check the space that you have identified it as being in. If you have just copied it directly from the Confluence examples then it has "key":"TST", but your get request gives "key":"AIENG". I had similar issues when trying to the same method and it was solely down to that, but equally I don't know if you have changed it on your example here just for display.

NB: auth also works without the HTTPBasicAuth (but I'm also very new to coding so it might be good practice!), and I've found data=payload tends to work better for me.

I'd also second the recommendation on the atlassian-python-api as it does make life a little easier.
