This endpoint is used to directly upload local files to Carbon. The `POST` request should be a multipart form request.
Note that the `set_page_as_boundary` query parameter is applicable only to PDFs for now. When this value is set,
PDF chunks are at most one page long. Additional information can be retrieved for each chunk, however, namely the coordinates
of the bounding box around the chunk (this can be used for things like text highlighting). Following is a description
of all possible query parameters:
- `chunk_size`: the chunk size (in tokens) applied when splitting the document
- `chunk_overlap`: the chunk overlap (in tokens) applied when splitting the document
- `skip_embedding_generation`: whether or not to skip the generation of chunks and embeddings
- `set_page_as_boundary`: described above
- `embedding_model`: the model used to generate embeddings for the document chunks
- `use_ocr`: whether or not to use OCR as a preprocessing step prior to generating chunks. Valid for PDFs, JPEGs, and PNGs
- `generate_sparse_vectors`: whether or not to generate sparse vectors for the file. Required for hybrid search.
- `prepend_filename_to_chunks`: whether or not to prepend the filename to the chunk text


Carbon supports multiple models for use in generating embeddings for files. For images, we support Vertex AI's
multimodal model; for text, we support OpenAI's `text-embedding-ada-002` and Cohere's embed-multilingual-v3.0.
The model can be specified via the `embedding_model` parameter (in the POST body for `/embeddings`, and a query 
parameter in `/uploadfile`). If no model is supplied, the `text-embedding-ada-002` is used by default. When performing
embedding queries, embeddings from files that used the specified model will be considered in the query.
For example, if files A and B have embeddings generated with `OPENAI`, and files C and D have embeddings generated with
`COHERE_MULTILINGUAL_V3`, then by default, queries will only consider files A and B. If `COHERE_MULTILINGUAL_V3` is
specified as the `embedding_model` in `/embeddings`, then only files C and D will be considered. Make sure that
the set of all files you want considered for a query have embeddings generated via the same model. For now, **do not**
set `VERTEX_MULTIMODAL` as an `embedding_model`. This model is used automatically by Carbon when it detects an image file.

For pre-filtering documents, using `tags_v2` is preferred to using `tags` (which is now deprecated). If both `tags_v2`
and `tags` are specified, `tags` is ignored. `tags_v2` enables
building complex filters through the use of "AND", "OR", and negation logic. Take the below input as an example:
```json
{
    "OR": [
        {
            "key": "subject",
            "value": "holy-bible",
            "negate": false
        },
        {
            "key": "person-of-interest",
            "value": "jesus christ",
            "negate": false
        },
        {
            "key": "genre",
            "value": "religion",
            "negate": true
        }
        {
            "AND": [
                {
                    "key": "subject",
                    "value": "tao-te-ching",
                    "negate": false
                },
                {
                    "key": "author",
                    "value": "lao-tzu",
                    "negate": false
                }
            ]
        }
    ]
}
```
In this case, files will be filtered such that:
1. "subject" = "holy-bible" OR
2. "person-of-interest" = "jesus christ" OR
3. "genre" != "religion" OR
4. "subject" = "tao-te-ching" AND "author" = "lao-tzu"

Note that the top level of the query must be either an "OR" or "AND" array. Currently, nesting is limited to 3.
For tag blocks (those with "key", "value", and "negate" keys), the following typing rules apply:
1. "key" isn't optional and must be a `string`
2. "value" isn't optional and can be `any` or list[`any`]
3. "negate" is optional and must be `true` or `false`. If present and `true`, then the filter block is negated in
the resulting query. It is `false` by default.

This endpoint revokes the access token for a particular data source connection.

Revoke Connection

This endpoint retrieves active connections across all data sources for a user.

View Connections

You can bypass the authentication flow on Carbon by directly passing in an access token. This endpoint eliminates the need for users to go through the typical authentication flow. By providing the access token directly, users can gain immediate access to Carbon's features and functionality without any additional steps.

Add Connection

This endpoint syncs all items in a user's data source connection. Note that only the directory structure and accompanying metadata will be synced, not the content within files.

Sync Connection

Use this endpoint to access and navigate a user's file directory, allowing you to create a custom file selector interface.

List Connection Items

After listing files and folders via /integrations/items/sync and integrations/items/list, use the selected items' external ids 
as the ids in this endpoint to sync them into Carbon. Sharepoint items take an additional parameter root_id, which identifies
the drive the file or folder is in and is stored in root_external_id. That additional paramter is optional and excluding it will
tell the sync to assume the item is stored in the default Documents drive.
