In this blog post, we will delve into the capabilities of the CustomGPT.ai RAG API, providing detailed instructions on how you can handle your project conversation management in the CustomGPT.ai RAG API browser to streamline your conversation management processes.
Managing Conversation
Now let’s see how you can manage to create, list, update, retrieve, and send messages to conversations directly from the CustomGPT.ai RAG API browser.
Before starting, ensure you have:
- A RAG API token from CustomGPT.ai.
- The projectId of the project you want to manage conversations within.
You can get this RAG API token and projectId from your CustomGPT.ai account.
Create Conversation
To create a new conversation in your CustomGPT.ai chatbot via RAG API, follow these steps:
- Authorization: Copy your RAG API key into the authorization box in the RAG API documentation.
- Project ID: From your chatbot settings, copy your project ID and place it in the designated box.
- Conversation Name: Provide a name for your new conversation.
Following is the pre-built code snippet that demonstrates how to send a POST request to the CustomGPT.ai RAG API endpoint to create a new conversation, which you can then use when retrieving messages from a conversation. All you have to do is enter the above information in the box as shown below:

Click “Try it” to execute the code. A successful POST request will return a status code 201, indicating that the new conversation was created successfully.

Now let’s see in our CustomGPT.ai interface whether a new conversation is created with the name we provided or not through the CustomGPT.ai API endpoints.

You see that we successfully created A new conversation in our chatbot project by making a CustomGPT.ai RAG API and Python HTTP request.
Update Conversation
To update a conversation using the CustomGPT.ai RAG API browser, you’ll authenticate with your RAG API key and navigate to the PUT endpoint for updating conversations within a specific project and session.
- Input the project ID and session ID to identify the conversation you wish to modify.
- Provide the desired updates in the request body, such as changing the conversation name or adjusting specific parameters.

- Execute the request, and upon successful completion, the conversation attributes will be updated accordingly, confirmed by a status code response indicating the operation’s success.

- Now let’s see the updated conversation in the CustomGPT.ai interface.

Retrieve Message within a Conversation
To retrieve messages from a conversation using the CustomGPT.ai RAG API, the GET endpoint will be utilized for accessing message data within a specified project and session. This GET RAG API endpoint facilitates the retrieval of a comprehensive collection of messages exchanged during a particular conversation. Each message typically includes content, timestamps, and other pertinent details shared throughout the conversation’s duration.
- To retrieve the message write the RAG API in the authorization box.
- Write other details such as Project ID and Session ID.

- Now run the code and see the response. The retrieved message and other details will be shown in the response body.

List Conversations
To list all conversations associated with a project using the CustomGPT.ai RAG API browser, the GET endpoint will be used for fetching conversation data. By providing the unique project ID, you can retrieve a collection of all conversations related to that specific project.
This process involves entering your RAG API key for authentication, navigating to the appropriate endpoint, and supplying the project ID.

Executing the request will return a list of conversations, each containing relevant details such as conversation names and IDs.

This method allows you to efficiently access and review all conversations within the specified project directly from the CustomGPT.ai RAG API browser.
Delete Conversation
To delete a conversation within a project using the CustomGPT.ai RAG API, the DELETE endpoint will be used. By providing the unique project ID and session ID, you can target the specific conversation you wish to remove. This endpoint will permanently delete the conversation along with all associated messages.
To perform this action, enter your RAG API key for authentication, navigate to the DELETE endpoint, and supply the required project ID and session ID.

Executing the request by clicking on “Try it” and it will result in the complete removal of the targeted conversation and its data, ensuring it is no longer accessible within the project context.

Frequently Asked Questions
How should I manage conversation state in a custom chat app?
u0022Powered by my custom-built Theory of Change AIM GPT agent on the CustomGPT.ai platform. Rapidly Develop a Credible Theory of Change with AI-Augmented Collaboration.u0022 — Barry Barresi, Social Impact Consultant. To keep that kind of custom experience consistent, create one conversation when a user starts a thread, store the returned session ID in your app, and send each follow-up message to that same conversation. Start a new conversation only when the user begins a genuinely new thread or topic. Use the update endpoint to rename or modify conversation metadata, not as the normal way to send the next user turn.
Can I use the Conversation RAG API behind WhatsApp or another messaging channel?
Yes. You can place WhatsApp or another messaging channel in front of the API, while your backend maps each user or phone number to a conversation or session ID. The messaging layer handles delivery, and the API handles conversation creation, history retrieval, updates, and deletion. The provided materials confirm API deployment and 1,400+ Zapier integrations, but they do not document a native WhatsApp-specific endpoint, so you should expect to connect it through your own app or integration layer.
How do I export conversations or pull all messages from yesterday?
The provided materials describe conversation listing and message retrieval, but they do not describe a dedicated export endpoint or a built-in ‘yesterday’ date filter. A practical approach is to list conversations, track timestamps in your app or database, retrieve messages for the matching session IDs, and then write the results to your reporting or warehouse system.
Can the Conversation RAG API handle multilingual conversations at scale?
Yes. You can manage conversations in 93+ languages through the same API. A clean setup is to keep one conversation per user thread and store the user’s preferred language in your application so routing, analytics, and exports stay organized across locales.
Can businesses use the Conversation RAG API to build a fully customized AI interface?
u0022Check out CustomGPT.ai where you can dump all your knowledge to automate proposals, customer inquiries and the knowledge base that exists in your head so your team can execute without you.u0022 — Stephanie Warlick, Business Consultant. Yes. You can build your own front end and use the API on the backend for conversation creation, message handling, retrieval, and cleanup. The provided materials also confirm support for custom personas, branding, and API-based deployment.
How is a conversation RAG API different from OpenAI’s chat API history?
u0022I just discovered CustomGPT, and I am absolutely blown away by its capabilities and affordability! This powerful platform allows you to create custom GPT-4 chatbots using your own content, transforming customer service, engagement, and operational efficiency.u0022 — Evan Weber, Digital Marketing Expert. In practice, a conversation RAG API gives you explicit conversation objects you can create, list, update, retrieve, and delete, while a basic chat-completions workflow usually requires your app to keep and resend prior turns itself. If you need grounded answers tied to your own content plus more auditable conversation records, that extra layer reduces session-management work. The provided materials also state the API is OpenAI-compatible at /v1/chat/completions and that it outperformed OpenAI in a RAG accuracy benchmark.
Does the Conversation RAG API store confidential user input for future conversations?
Conversation data can persist so you can retrieve or delete it later, which means user input may remain available within that conversation unless you remove it. The provided materials do not say that confidential input is automatically reused across unrelated new conversations. For security, the available credentials say the service is SOC 2 Type 2 certified, GDPR compliant, and does not use customer data for model training. If you handle sensitive data, set clear retention and deletion rules in your own system and delete old conversation records on schedule.
