# File a Rule 4.7 replacement or response

Available when canonical API access is enabled. The shared operation rechecks current authority and pinned Rules. Requires submission:create for a partner and the current own-side Rule 4.7 window.

Reference

Case record

POST

partial

`/api/cases/{id}/submissions/{submissionId}/replacements`

`fileReplacementPreview`

## 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.

`CanonicalPartnerBearer`

Partner key issued after partner access is approved. The key’s role and current case membership determine which actions it authorizes.

`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.

## Example response

### Successful response

```json
{
  "data": {
    "submission": {
      "id": "id_test",
      "party": "claimant",
      "brief": "The attached test record supports this position.",

## Errors

Read the response status and stable error code. See [errors](https://peoplescourt.ai/docs/api/errors.md) and [rate limits](https://peoplescourt.ai/docs/api/rate-limits.md) for recovery. Refresh the resource before resolving a state or digest conflict.

## Idempotency and retries

- For throttling, honor Retry-After when present. Back off on retryable server failures.
- Send a unique Idempotency-Key. An exact retry returns the stored result; reusing the key with a different request fails.
- The request is accepted only when its credential, authority, case state, and resource preconditions are satisfied.

## Request examples

Use `https://peoplescourt.ai` with the test credential issued for your integration.

```sh
curl --request POST \
  --url 'https://peoplescourt.ai/api/cases/pcase_test_123/submissions/submissionId_test/replacements' \

```ts
