# Resumable upload Users uploading larger files and/or with poor connectivity can initiate a resumable upload session with the resumable_upload_url from the upload_request body. Google provides some great documentation on resumable uploads (as the content will be uploaded to Google Cloud Storage). > NOTE: Resumable Uploads use the POST method on initialization and the PUT method after to resume upload. > NOTE: After uploading a file, you can add it as Brandfolder asset by copying the object_url value from the [Get an upload URL](/api/brandfolder/openapi/binary_upload/opidstorageserviceuploadrequestsget) response into your request body's attachments.url property. See [Create assets in a Brandfolder](/api/brandfolder/openapi/assets/opidapiv4collectionsassetsbybrandfolderidpost) for details. Endpoint: POST /resumable_upload_url Version: v4 Security: ## Header parameters: - `x-goog-resumable` (string, required) Enum: "start" ## Response 201 fields (application/json): - `location` (string) Example: "https://storageservice.com/bf-upload-request/signed-resumable-upload-url\n"
