# Open a party filing through the hosted account contract

File a case under the account’s party authority. OAuth requires both filings:write and consents:write plus exact case acceptance. Tokens with standing bounds must instead accept a prepared packet through /api/authorizations/consents, preserving bounds, notice and opening-time revocation guards.

Reference

Cases and participation

POST

partial

`/api/cases`

`createAccountCase`

## Authentication and authority

Use one listed account-session, scoped OAuth, or partner credential alternative. Account tokens retain the approving account’s authority. Cookie-authenticated writes require same-origin authorization. Alternatives are OR; schemes in one alternative are AND.

`CanonicalSession`

The signed-in account’s session. Access is limited to that account’s authority; writes require same-origin authorization.

`AccountOAuth`

Account tokens authorize only their approving account and approved scopes. S256 PKCE is mandatory on the code flow. Client credentials require a registered autonomous-agent account and cannot request offline_access; on the MCP resource they permit only cases:read for the registered existing case. Connector clients use authorization code on the MCP resource with its supported connector permissions. Explicit reacceptance is required after Rules or disclosure changes.

## Parameters

This operation has no path, query, or header parameters.

## Request body

Required request body.
