I'm trying to post to a create a Confluence page via a browser app.
I've set up my OAuth 2.0 (3LO) authentication, my url is configured correctly, I've (temporarily) added all scopes to my app, and ensured that I have the most possible permissions in my Confluence instance.
POSTing to JIRA works fine, GETting from Confluence works fine, but everytime I try to POST to Confluence, I get a 403 response with the text 'XSRF check failed'.
I am running my app locally, so it's coming from 'http://localhost:8000', but I thought OAuth handles any CORS problems.
I'm happy to share any code or specific info, but I could really use some help here.
