Ingestion gives Supermemory the source material it uses to build searchable context and memories. Add new content or update an existing source without creating a disconnected copy.

| Operation | Purpose |
| --- | --- |
| `POST /ns/{namespace}/document` | Add text or a URL; reuse an ID to build on an existing document |
| `POST /ns/{namespace}/document/batch` | Bring in up to 600 documents together |
| `POST /ns/{namespace}/document/file` | Turn an uploaded file into searchable memory |
| `PATCH /ns/{namespace}/document/{id}` | Update metadata or replace canonical content |
| `POST /ns/{namespace}/document/file/{id}` | Completely replace a file-backed document |
| `PATCH /ns/{namespace}/document/file/{id}` | Refresh selected file details or its source |

The `dynamic` processing mode (default) groups related documents together so memories form from coherent, logical units rather than one isolated entry at a time. Use `instant` to process each document on its own right away; it bills one extra operation per document.

Every request is scoped to a namespace, keeping each user, project, or tenant isolated. See [document write migration](/migration/api-v5-document-writes).
