Batch process all your records to store structured outputs in Vectara. The requirements are as follows. The Vectara connector dependencies. 
pip install "unstructured-ingest[vectara]"
You might also need to install additional dependencies, depending on your needs. Learn more. The following environment variables:
  • VECTARA_CUSTOMER_ID - The customer ID for the target Vectara account, represented by --customer-id (CLI) or customer_id (Python).
  • VECTARA_CORPUS_NAME - The name of the target corpus in the account, represented by --corpus-name (CLI) or corpus_name (Python).
  • VECTARA_CORPUS_KEY - The name of the corpus’s key, represented by --corpus-key (CLI) or corpus_key (Python).
  • VECTARA_OAUTH_TOKEN_URL - The OAuth token URL for getting and refreshing OAuth access tokens in the account, represented by --token-url (CLI) or token_url (Python).
  • VECTARA_OAUTH_CLIENT_ID - A valid OAuth client ID in the account, represented by --oauth-client-id (CLI) or oauth_client_id (Python).
  • VECTARA_OAUTH_CLIENT_SECRET - The OAuth client secret for the client ID, represented by --oauth-client-secret (CLI) or oauth_client_secret (Python).
Now call the Unstructured CLI or Python SDK. The source connector can be any of the ones supported. This example uses the local source connector. This example sends files to Unstructured for processing by default. To process files locally instead, see the instructions at the end of this page.

For the Unstructured Ingest CLI and the Unstructured Ingest Python library, you can use the --partition-by-api option (CLI) or partition_by_api (Python) parameter to specify where files are processed:
  • To do local file processing, omit --partition-by-api (CLI) or partition_by_api (Python), or explicitly specify partition_by_api=False (Python). Local file processing does not use an Unstructured API key or API URL, so you can also omit the following, if they appear:
    • --api-key $UNSTRUCTURED_API_KEY (CLI) or api_key=os.getenv("UNSTRUCTURED_API_KEY") (Python)
    • --partition-endpoint $UNSTRUCTURED_API_URL (CLI) or partition_endpoint=os.getenv("UNSTRUCTURED_API_URL") (Python)
    • The environment variables UNSTRUCTURED_API_KEY and UNSTRUCTURED_API_URL
  • To send files to the Unstructured Partition Endpoint for processing, specify --partition-by-api (CLI) or partition_by_api=True (Python). Unstructured also requires an Unstructured API key and API URL, by adding the following:
    • --api-key $UNSTRUCTURED_API_KEY (CLI) or api_key=os.getenv("UNSTRUCTURED_API_KEY") (Python)
    • --partition-endpoint $UNSTRUCTURED_API_URL (CLI) or partition_endpoint=os.getenv("UNSTRUCTURED_API_URL") (Python)
    • The environment variables UNSTRUCTURED_API_KEY and UNSTRUCTURED_API_URL, representing your API key and API URL, respectively.
    You must specify the API URL only if you are not using the default API URL for Unstructured Ingest, which applies to Starter and Team accounts.The default API URL for Unstructured Ingest is https://api.unstructuredapp.io/general/v0/general, which is the API URL for the Unstructured Partition Endpoint. However, you should always use the URL that was provided to you when your Unstructured account was created. If you do not have this URL, email Unstructured Support at support@unstructured.io.If you do not have an API key, get one now.If you are using an Enterprise account, the process for generating Unstructured API keys, and the Unstructured API URL that you use, are different. For instructions, see your Unstructured account administrator, or email Unstructured Support at support@unstructured.io.
