HOW TO: User upload a file to trigger the chat
# support
s
i'm trying to create an agent that on top of the knowledge base, will have the ability to have injected context before the chat session starts with the user. User flow: uploads file (additional context needed for session) --> clicks start --> session begins Im thinking i need to do this but i need to know how, SPECIFICALLY Context Injection: When the chat session begins, retrieve the stored context using the session identifier and inject it into the chat environment. This will allow your agent to use the context during the conversation.

@Suri That's a great approach to enhance the capabilities of your agent by providing it with additional context. To implement context injection for your agent, you would typically follow these steps: 1. **Context Storage**: When the user uploads a file, you need to have a mechanism to parse and store the relevant information from that file. This could be done by saving the data in a database or in-memory storage with a unique session identifier. 2. **Session Initialization**: When the user clicks 'start' to begin the session, your system should generate a unique session identifier that can be used to retrieve the stored context. 3. **Context Retrieval**: At the beginning of the session, your system should use the session identifier to retrieve the stored context from your storage solution. 4. **Context Injection**: Once the context is retrieved, you need to inject it into the chat environment. This could be done by setting the context as part of the initial state of the chat session or by using an API that allows you to set the context for the session. 5. **Agent Utilization**: Your agent should be designed to understand and utilize the injected context to provide relevant responses and actions during the conversation. To implement this, you would need to have the following components: - A file upload mechanism on the frontend. - A backend service to handle file parsing, context extraction, and storage. - A session management system to create and manage session identifiers. - A chat environment that supports context injection. - An intelligent agent that can understand and use the context. If you need assistance with specific parts of this process, such as file parsing, context storage, or modifying the chat environment to accept context, please let me know which part you need help with, and I can provide more detailed guidance.

@Vapi the data is parsed and sitting on supabase, looking how to do the ACTUAL context injection, basically #4 of your point. give me exact steps
@Vapi where did u go

Hey @Suri Vapi agent doesn't supports text-chat, and I am assuming you meant for voice based chat. Now** context injection** is easy using assistant overrides you can pass the previous call context right before the call. checkout this document on setting up dynamic variables, now when Vapi will send request to your server (in-doc-context) you can then pass the context of previous calls as role

https://www.notion.so/vapi/Setting-Up-Dynamic-Variables-for-Your-Vapi-Calls-A-Quick-Guide-140008c8393f8057ac24db4089edc466 For the KB: As of now KB is not working because our vendor has stopped their services, and we are working on integrating other providers. So, wait for this week, Because once you upload the file, the files goes for emebedding which takes some time (few seconds) after that file is made ready to use. Thus, to get the correct solution revolving around KB I suggest waiting for this week.
@Suri do let if you require more help.

@Shubham Bajaj thanks for the reply. If I want text to show up as well along side voice, what would be a preferred method
Also who was the vector store provider so I know not to use them?

You can read more current KB development https://docs.vapi.ai/knowledgebase
There is no preference for realtime text and voice chat. If you want to show relatime transcription, use server event to conversation-update/transcript to show the realtime transcription.
@Suri do let me know if your queries are resolved, and I can close this ticket.

hey, have still been looking into this. my agent at the moment gets the file injected into context but does not reference the file unless the user asks about it. e.g.) the file is a resume, the prompts ensure that the agent is supposed to ask questions tailored to the resume - but this isnt happening. Because I can ask questions about the resume to the agent, i can confirm the injection is working.
When searching with GPT search for a solution, it brings me back to this [chat](https://support.vapi.ai/t/23456624/how-to-user-upload-a-file-to-trigger-the-chat)

@Suri create a new support ticket for this, and share the description in the following format:- Hey! To help track down this issue, could you share: - The call ID - When exactly this happened (the timestamp) - What response you expected to get - What response you actually got instead This would really help me figure out what went wrong!
