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

> Replace the content of an existing A+ document, keeping its key and ASIN links — to revise copy, module order or images without creating a new document.

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

ASIN links change through aplusContent_postContentDocumentAsinRelations. Amazon SP-API · updateContentDocument · POST /aplus/2020-11-01/contentDocuments/{contentReferenceKey} 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.

## 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). |
| `contentDocument` | object | yes | The full new document body — same shape as create. Required: name (maxLength 100), contentType (Allowed: EBC = Seller Central A+, use this for seller accounts \| EMC = Vendor Central A+), locale (IETF tag, HYPHENATED — pattern ^[a-z]{2,}-[A-Z0-9]{2,}$, e.g. 'en-US'), contentModuleList (1–100 modules). Optional: contentSubType. See aplusContent_create_and_publish for the module shape and text limits (contentModuleType values: the Body block). |

## Result

- `data.contentReferenceKey` — same as input.
- `data.warnings` — (only when present) Amazon's warnings — the notification is then a warning.

## Gotchas

- SUBMITTED or APPROVED content: suspend it first (aplusContent_postContentDocumentSuspendSubmission), update, then resubmit.

## Workflow

- 1. aplusContent_getContentDocument for the current contentDocument. 2. Change it (e.g. a STANDARD_HEADER_IMAGE_TEXT module's headline) and call this tool with the whole document. 3. aplusContent_postContentDocumentApprovalSubmission to publish the new version.
