This may be similar to squad concept. I used the vapi squad option but still facing issues because the second prompt requires some data collected after conversation using first prompt.

You can continue this conversation by mentioning me in the message.

@User @User

@Hasan The API endpoint at

https://docs.vapi.ai/api-reference/calls/update-call

is used for updating the details of an ongoing or completed call within the VAPI (Voice API) platform. This could involve changing call-related parameters, such as updating the call's state, modifying the call flow, or attaching additional data to the call record for analytics or record-keeping purposes. Typically, this API would be called programmatically during or after a call session to ensure that the call's metadata reflects any changes that occurred during the call's lifecycle. It's an essential part of managing call states and data within applications that use VAPI for voice interactions. If you need to update a call or have any specific parameters you wish to modify, please provide the details, and I can guide you on how to use the API effectively.

@Vapi what is the difference between update assistant api and this api

@Hasan The "Update Assistant" API and the "Update Call" API serve different purposes within the VAPI platform: 1. **Update Assistant API**: This API is used to update the configuration or settings of an assistant. An assistant in VAPI is a virtual entity that can handle tasks such as managing dialogues, understanding user inputs, and providing appropriate responses. When you update an assistant, you might change its behavior, the way it processes information, or how it interacts with users. 2. **Update Call API**: On the other hand, the "Update Call" API is specifically for updating the details of a voice call in progress or completed. This could involve changing the call's state, modifying the call flow, or adding additional data to the call record. It's more focused on the telephony aspect and managing individual call instances. In summary, the "Update Assistant" API is about configuring the assistant's behavior and capabilities, while the "Update Call" API is about managing the state and details of specific call sessions.

@Vapi so using update call api, I can also change the system prompt of the ongoing call

@Hasan No, the "Update Call" API is typically not used for changing system prompts during an ongoing call. System prompts are usually defined by the call flow or the assistant's logic, which determines what the user hears during a call. If you want to change the system prompts dynamically during an ongoing call, you would generally use methods provided by the call control APIs that allow you to play audio, send text-to-speech prompts, or control the call flow in real-time. These methods are designed to interact with the call as it happens, allowing you to modify the user experience on the fly. For changing prompts during an ongoing call, you would look for APIs that handle call interactions, such as playing messages, collecting input, or transferring calls. If VAPI provides such an API, it would be the appropriate choice for updating system prompts during a call. If you need to update the prompts for an ongoing call and are unsure how to proceed, please provide more details about your use case, and I can guide you further.

@Vapi when was this api for update call released

@Hasan Please ask support for more info on this.

@Sahil please guide

@Hasan you cannot update ongoing call system prompt.

@Shubham Bajaj Basically, I am collecting some required information through one assistant like timezone, income etc. The information of user's timezone is critical for appointment booking assistant so that the current local time of user can be known and used as a reference to evaluate the datetime in some standard format to check against the calendar.

@Hasan allow me sometime to check If I can find anything for it, If I don't respond within next 24hours do ping me.
