Upload Session Append Batch

View as MarkdownOpen in Claude
Append more data to multiple upload sessions. Each piece of file content to append to each upload session should be concatenated in the request body, in the order delineated by `UploadSessionAppendBatchArg.entries` and their individual lengths indicated by `UploadSessionAppendBatchArgEntry.length`. A single request should not upload more than 150 MiB. The maximum size of a file one can upload to an upload session is 2^41 - 2^22 (2,199,019,061,248) bytes. Calls to this endpoint will count as data transport calls for any Dropbox Business teams with a limit on the number of data transport calls allowed per month. For more information, see the Data transport limit page https://www.dropbox.com/developers/reference/data-transport-limit. **Required scope:** `files.content.write` **Endpoint format:** [Content-upload](https://docs.dropboxapi.com/dropbox-api/docs/technical-reference/request-response-formats#content-upload-endpoints) **Authentication:** [User](https://docs.dropboxapi.com/dropbox-api/docs/auth-types#user-authentication), [Dropbox-API-Select-Admin (Team Admin)](https://docs.dropboxapi.com/dropbox-api/docs/auth-types#admin-authentication-via-dropbox-api-select-admin)

Authentication

AuthorizationBearer
OAuth 2.0 token issued to a specific user. Use `Authorization: Bearer <token>`. Public clients should use the authorization code flow with PKCE (S256). For background or offline access, send `token_access_type=offline` during authorization and use the returned refresh token to obtain new access tokens. You can generate a short-lived access token from the App Console; see [Testing with a generated token](https://docs.dropboxapi.com/dropbox-api/docs/oauth#testing-with-a-generated-token).
