Webhooks

LLMWhisperer from V2 onwards supports webhooks. You can now register a webhook and use it to receive the processed document.

Requirements

• A publicly accessible URL to receive the webhook. (Can be internal in on-prem installations)
• The URL must be able to receive POST requests.
• The URL must be able to handle the payload sent by the webhook.
• Only Bearer token authentication is supported for webhooks.
• The webhook must return a 200 status code to acknowledge receipt of the payload.
• A maximum of 3 retries will be made in case of a failure. (Can be changed in on-prem installations)

Payload

The payload sent to the webhook will be a JSON object with the following structure:

{
  "payload_status": {
    "status": "success",            # The status of the payload.
    "message": ""                   # Message in case of error
    "whisper_hash": "<WHISPER_HASH>" # Whisper hash of intiated request.
  },
  "line_metadata": [],              # Refer to retrieve API for details
  "confidence_metadata": [],        # Refer to retrieve API for details
  "result_text": "extracted_text",  # The extracted text
  "metadata": {}                    # Refer to retrieve API for details
}

Setting up a webhook

To set up a webhook, you need to provide the following details:

• url (str, required): The URL of the webhook to call after the document is processed.
• auth_token (str, required): The Bearer token to use for authentication. Note: Pass the token alone without the 'Bearer' keyword.
• webhook_name (str, required): The name of the webhook to register.

Once the webhook is registered, it can be used in the whisper API to deliver the payload after processing the document.
