# aplusContent_postContentDocumentAsinRelations (https://sellersheetai.com/docs/mcp-api/tools/aplusContent_postContentDocumentAsinRelations)

> Replace all ASINs linked to an existing A+ content document.

Access: **DESTRUCTIVE** · toolset amazon_sp · family sp.aplusContent_2020-11-01

Amazon SP-API · postContentDocumentAsinRelations · POST /aplus/2020-11-01/contentDocuments/{contentReferenceKey}/asins Gate: approve — interactive: show the change (Amazon's preview first where one exists), wait for an explicit approve; autopilot: only when the seller's own words asked for this change; otherwise ask. This is a FULL replacement — the new asinSet becomes the complete set of linked ASINs. Any ASIN omitted from asinSet will have A+ content suspended on its listing. Always include ALL ASINs you want linked, not just the new ones.

## Call it

MCP tool call:

```json
{
  "name": "aplusContent_postContentDocumentAsinRelations",
  "arguments": {
    "store": "myStore-US",
    "contentReferenceKey": "<contentReferenceKey>",
    "asinSet": []
  }
}
```

Tool API (early access — contact us):

```bash
curl -X POST https://api.sellersheetai.com/api/v1/tools/aplusContent_postContentDocumentAsinRelations \
  -H "Authorization: Bearer $SELLERSHEET_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"store":"myStore-US","contentReferenceKey":"<contentReferenceKey>","asinSet":[]}'
```

## Arguments

| Name | Type | Required | Description |
|---|---|---|---|
| `store` | string | yes | the store ref `<store>-<CC>` (name-country, e.g. 'myStore-US') — one of get_user_context's store_refs, verbatim. |
| `contentReferenceKey` | string | yes | the A+ content document key (from aplusContent_searchContentDocuments). |
| `asinSet` | string[] | yes | New complete set of ASIN strings. All previously linked ASINs not in this list will be suspended. |

## Result

- `data.contentReferenceKey` — same as input.
- `data.asinCount` — number of ASINs sent.
- `data.warnings` — (only when present) Amazon accepted the call but did not apply all of it — the notification is then a warning.

## Workflow

- 1. aplusContent_listContentDocumentAsinRelations for the current set of linked ASINs. 2. Merge existing ASINs with new ones (or remove specific ones). 3. Optionally aplusContent_validateContentDocumentAsinRelations to check eligibility. 4. Call this tool with the complete new asinSet. 5. If the document is DRAFT, submit it with aplusContent_postContentDocumentApprovalSubmission. 6. Write the updated ASIN list to your tracking sheet.
