Upload a file to the corpus

POST 
/v2/corpora/:corpus_key/upload_file

Upload files such as PDFs and Word Documents. Vectara will attempt to automatically extract text and any metadata. The File Upload endpoint request expects a multipart/form-data request containing the following parts:

• metadata - (Optional) Specifies a JSON object representing any additional metadata to be associated with the extracted document. For example, 'metadata={"key": "value"};type=application/json'
• file - Specifies the file that you want to upload.
• filename - Specified as part of the file field with the file name that you want to associate with the uploaded file. For a curl example, use the following syntax: 'file=@/path/to/file/file.pdf;filename=desired_filename.pdf'

For more detailed information, see this File Upload API guide.
