Objective

The goal of this integration is to validate order information for Groucho’s Deli via an AI assistant (Amelia) using VAPI to guide customers through the ordering process. The system will validate each item ordered in real-time to ensure required fields are filled. This involves retrieving and validating options for menu items based on their unique identifiers (menuItemID) and relaying feedback to the customer for incomplete entries.

Current Status

VAPI Tool Configuration

Tool Name: ValidateOrder

Purpose: This tool is intended to validate required fields for each ordered menu item before finalizing the order. It checks for completeness based on specific fields associated with each menuItemID.

Recent Modifications to Prompt and Workflow

We’ve adjusted the prompt to guide the AI assistant (Amelia) through a structured conversation flow for ordering. Here’s an overview of the key steps and modifications:

  1. Step-by-Step Conversation Flow:

    • Prompt Modification: Amelia’s conversation flow was structured in detailed steps, with conditions to handle different user responses (e.g., takeout vs. delivery, specific order times).

    • Real-Time Validation: The modified prompt ensures that Amelia requests all required details in a specific order. If options are missing, the assistant will clarify and ask for the missing options as part of the ordering process, providing real-time guidance.

  2. Order Validation Using ValidateOrder Tool:

    • Step 3d in the prompt specifies that, after collecting options, Amelia should call the ValidateOrder tool to ensure each item has all required fields before adding it to the order.

    • Missing Fields Check: If the validation fails (i.e., any required fields are missing for a given menuItemID), Amelia will be prompted to ask clarifying questions based on the missing requirements.

    • Error Handling: If any field is missing or incorrect, ValidateOrder will respond with a list of missing fields, which Amelia will use to ask the customer for the missing details.

Tool Parameters Configuration

The following parameters have been configured for the ValidateOrder tool in VAPI to support real-time validation:

  1. menuItemID - (string) Unique identifier for each ordered item.

  2. selectedOptions - (array of strings) Options selected by the customer, such as toppings or side choices.

  3. orderType - (string) Indicates if the order is for "takeout" or "delivery".

  4. deliveryAddress - (string) Address for delivery orders (only required if orderType is "delivery").

  5. orderTime - (string) Specifies whether the order is "as soon as possible" or at a specific time.

  6. orderItems - (array) List of items in the order with their quantities and options.

  7. orderTotal - (number) Total amount for the order.

  8. phoneNumber - (string) Customer’s phone number to send confirmation.

  9. customerName - (string) Customer’s name.

These parameters allow ValidateOrder to handle necessary validation logic for each item based on its menuItemID, check selected options, and manage overall order details.

Pipedream Workflow Configuration

Pipedream Trigger URL: https://eo5ucr6l0cswrve.m.pipedream.net

Objective: This URL acts as the entry point for data received from VAPI when an order is submitted for validation.

  1. Trigger:

    • Configured to receive a full HTTP request from VAPI with order data.

    • The incoming payload includes the fields listed above, as VAPI sends them directly to this URL.

  2. Current Setup:

    • We’ve configured a basic HTTP request trigger in Pipedream to capture the order data payload.

    • The trigger setup is incomplete as we are still verifying that the test data sent from VAPI reaches Pipedream correctly.

Testing Steps Completed

  1. Parameter Setup in VAPI: The parameters for ValidateOrder have been defined as per the conversation flow and requirements.

  2. Trigger URL Noted: We’ve identified and saved the unique Pipedream URL that will receive data from VAPI.

  3. Initial Test Execution:

    • A test request was set to be sent from VAPI using the parameters defined in ValidateOrder.

    • The goal was to confirm that the test data arrives in Pipedream successfully, allowing us to proceed with further validation logic in Pipedream.

  4. Validation Pending:

    • We are awaiting confirmation that the test data from VAPI arrives at Pipedream in the expected format.

    • Once data is confirmed to be received in Pipedream, further logic will be implemented to validate each item, check for required fields, and handle any missing or incorrect data.

Planned Real-Time Validation Process

The real-time validation process will proceed as follows:

  1. Step-by-Step Prompt Execution in VAPI:

    • Amelia will follow the prompt’s structured conversation flow, requesting specific information at each step.

    • For each item ordered, Amelia will request required options based on the menuItemID.

  2. Calling ValidateOrder Tool for Each Item:

    • Once all options for an item are collected, the ValidateOrder tool will be triggered to verify completeness.

    • If validation fails (e.g., due to missing required fields), Amelia will prompt the user to provide the missing information in real-time.

  3. Final Order Validation and Confirmation:

    • After all items are validated, Amelia will summarize the order, confirm the total, and ask for a contact number for SMS confirmation.

    • The final order details (including customer information, items, and total) will be sent to Pipedream for final processing and order confirmation SMS.

Next Steps for the Developer

  1. Confirm Data Flow from VAPI to Pipedream:

    • Trigger a test in VAPI by calling ValidateOrder with sample data and ensure that it successfully reaches the Pipedream trigger URL (https://eo5ucr6l0cswrve.m.pipedream.net).

    • Verify that the data arrives in the expected format with all parameters intact.

  2. Build Validation Logic in Pipedream:

    • Once data is received, implement the necessary validation steps in Pipedream to handle each menuItemID and associated options.

    • If any required fields are missing, configure Pipedream to respond with an error message listing the missing fields.

    • If all fields are valid, proceed with further steps (such as sending order confirmations or updating order status).

  3. Testing and Debugging:

    • After implementing validation, test the end-to-end flow from VAPI to Pipedream, including various scenarios (e.g., missing fields, incorrect options).

    • Ensure that error messages and confirmations are handled smoothly based on the validation results.

  4. Documentation and Finalization:

    • Document the final workflow steps and logic within Pipedream, ensuring the integration is well-documented for future reference and troubleshooting.

    • Finalize the setup by enabling live data flow once testing is successful.
