# Migrate document ingestion to v5

> Upgrade single, batch, and file ingestion without changing append behavior

## Migration details

v5 moves document scope into the URL and keeps repeated caller IDs attached to one evolving document.

### Rename common fields

| Legacy | v5 | Location |
| - | - | - |
| `containerTag` | `{namespace}` | Path |
| `customId` | `id` | JSON body |
| `entityContext` | `supportingContext` | JSON/form body |
| `filterByMetadata` | `group` | JSON/form body |
| `documentDate` | `date` | JSON/form body |
| `taskType`, `dreaming` | unchanged | Query string |

### Add or append one document

<CodeGroup>
  ```bash Legacy theme={null}
  POST /v3/documents
  {"content":"new turn","customId":"conv_1","containerTag":"user_1"}
  ```

  ```bash v5 theme={null}
  POST /ns/user_1/document?dreaming=dynamic
  {"content":"new turn","id":"conv_1"}
  ```
</CodeGroup>

The response remains an acceptance result with `id` and `status`. Repeating the v5 request with `id: "conv_1"` adds or diffs the new content into that document; it does not silently replace the canonical source.

### Batch ingestion

<CodeGroup>
  ```json Legacy theme={null}
  {"documents":["first","second"],"containerTag":"user_1"}
  ```

  ```json v5 theme={null}
  {"documents":[{"content":"first","id":"doc_1"},{"content":"second","id":"doc_2"}]}
  ```
</CodeGroup>

Send the v5 body to `POST /ns/user_1/document/batch`. The array accepts 1–600 document objects. Namespace, `taskType`, and processing mode apply to the request; document content, ID, context, metadata, grouping, and date stay per item.

Batch results preserve input order. Inspect `success`, `failed`, and every item in `results`; a batch can contain successful and failed items together.

### File ingestion

Replace `POST /v3/documents/file` with `POST /ns/{namespace}/document/file`. Continue using `multipart/form-data`:

| Part | Encoding |
| - | - |
| `file` | Binary file |
| `supportingContext`, `date` | Plain strings |
| `metadata`, `group` | JSON-encoded strings |
| `fileType`, `mimeType` | Query parameters when inference is insufficient |

The API acknowledges the file after durable acceptance. Extraction, indexing, and memory formation continue asynchronously; poll the document rather than assuming the first response means processing is complete.

### Processing choices

* `taskType=memory` extracts long-term memories; `taskType=superrag` indexes source context without memory generation.
* `dreaming=dynamic` (default) groups related documents into coherent memory units.
* `dreaming=instant` processes each document independently and bills one extra operation per document.

### Verification

* Ingest text, a public URL, and a file, then wait for each document to finish processing.
* Repeat a caller-defined ID and confirm append/diff behavior instead of replacement.
* Submit a mixed-success batch and verify result order and per-item errors.
* Confirm metadata and grouping remain filterable after processing.
