Written by Corbin ai - February 02, 2024

Welcome back to Corbin AI! In this tutorial, I will show you step by step how to build an assistance API that requires no code and set up automations for answering emails in customer service. This guide will provide you with a pragmatic way to start applying AI in your business.

Comprehensive Description and Analysis

In this tutorial, we will use the assistance API from OpenAI and Zapier to create a customer service bot or assistant trained on our business data. The tutorial will cover how to gather and format the relevant information, set up the assistance API, and integrate it with Zapier for practical use cases. By following the steps outlined in this guide, you will be able to automate customer service tasks and improve efficiency.

How to Use Assistance API with No Code

The assistance API allows us to create a customer support agent or assistant without writing any code. It provides the ability to save chats and build on top of existing instructions to cater to specific use cases and contexts. With the OpenAI assistance API and Zapier integration, we can automate email responses and streamline customer service processes.

Creating the Assistance API

To create the assistance API, we will start by accessing the OpenAI front end. We will name our assistant "Customer Service" and specify that it is trained on our business data. Additionally, we will select the GBT-4 1106 preview model, which offers a more affordable option for training models. We will choose the retrieval format to allow the use of files and format them correctly using .txt files for maximum efficiency.

Gathering and Formatting Business Data

In order to train our assistant on relevant information, we need to gather and format our business data effectively. This can include FAQs, email chains, conversations, and any other data that is commonly encountered in customer service interactions. For our tutorial, we will start by extracting information from our website, particularly the FAQ, About, and Licenses pages. We will create a text file containing the relevant information in a structured format.

Training the Assistant and Verifying Results

Once we have formatted the business data, we will upload it to the assistance API. We can then use the OpenAI Playground feature to test and verify the results. This allows us to check if the assistant is trained on the data and provides accurate responses. By iterating and refining the instructions, we can optimize the assistant's performance and ensure that it meets our specific requirements.

Setting Up Zapier Automations

With the assistance API trained and verified, we can now integrate it with Zapier to create practical automations for customer service tasks. Zapier allows us to connect various apps and automate workflows. In this guide, we will focus on integrating the assistance API with Gmail to automate email responses.

Creating a Zap

To get started, we will create a new zap in Zapier. We will set the trigger as a new email in Gmail, specifically filtering for emails with the subject line "New Customer Message." This ensures that the automation is only triggered when relevant customer inquiries are received.

Integrating the Assistance API with Zapier

Within the zap, we will use the "Conversation with Assistant" feature in the assistance API. This allows us to generate a response based on the email inquiry received. We will provide the necessary prompts and specify the format of the response we want. By leveraging the power of the assistance API, we can generate accurate and contextually appropriate email responses.

Creating Email Drafts with AI-Powered Responses

Using the output from the assistance API, we can create draft email responses in Gmail. This allows us to review and edit the responses before sending them to customers. We can customize the subject line, add signatures, labels, and attachments as needed. By automating the email drafting process, we can save time and ensure consistent and efficient customer service.


Implementing AI-powered customer service can greatly enhance efficiency and productivity in your business. By using the assistance API with no code and integrating it with Zapier automations, you can automate email responses, streamline customer service tasks, and provide accurate and timely support to your customers. With the step-by-step guide provided in this article, you have all the tools you need to get started. Embrace the power of AI and transform your customer service operations today!

    A: Absolutely! The assistance API can be trained on various types of data, allowing you to create assistants for different use cases. Whether it's generating ebooks, providing sales support, or assisting with internal processes, the versatility of the assistance API opens up a world of possibilities.

  • Q: How should I structure my business data for training the assistant?

    A: It is important to format your business data correctly to ensure optimal training. Use .txt files and focus on including the most relevant information while minimizing unnecessary data. This will optimize the training process and improve the assistant's performance.

  • Q: Can I customize the email responses generated by the assistant?

    A: Yes, you can customize the email responses generated by the assistant. By providing specific instructions and prompts, you can shape the tone and content of the responses. Experiment with different instructions to find the style that best aligns with your business and customer service goals.

  • Q: How can I further optimize the performance of the assistant?

    A: To optimize the performance of the assistant, iterate and refine the instructions provided during training. Test different prompts and evaluate the responses to ensure they meet your requirements. Additionally, gather feedback from actual customer interactions to continuously improve and enhance the assistant's capabilities.

  • Q: Can I use the assistant API in other automation platforms besides Zapier?

    A: While this guide focuses on integrating the assistant API with Zapier, you can use it with other automation platforms that support API integrations. The versatility of the assistant API allows you to leverage its power in various contexts and workflows.
