Hello, I am developing a dashboard for customers using VAPI APIs in PHP. I am fetching the call logs of multiple assistants at once, but it is taking a lot of time to fetch the data. Is there any way to reduce the response time of the API?

Hi there! 👋 I understand you're experiencing slow response times when fetching call logs for multiple assistants in your PHP dashboard. I can definitely help with some strategies to improve this! While I don't have PHP-specific implementation details for VAPI, I can share several effective approaches to reduce API response time when fetching call logs: ### 1. Use Filtering and Pagination Utilize the API's filtering and pagination parameters to limit the amount of data returned:

https://api.vapi.ai/logs?assistantId=YOUR_ASSISTANT_ID&page=1&limit=100

According to the [VAPI API documentation](https://docs.vapi.ai/api-reference/logs/get), you can use parameters like: -

assistantId

to filter by specific assistant -

page

for pagination (defaults to 1) -

limit

to control results per page (defaults to 100, max 1000) ### 2. Implement Date Range Filtering Narrow down results by specifying date ranges:

https://api.vapi.ai/logs?createdAtGte=2025-03-01T00:00:00Z&createdAtLte=2025-03-21T00:00:00Z

This significantly reduces the data being processed and transferred. ### 3. Consider Using Webhooks Instead of repeatedly polling for logs, implement webhooks to receive real-time updates:

serverMessages: ['end-of-call-report']

According to [VAPI documentation](https://docs.vapi.ai/server-url/events), this approach sends you an end-of-call report after each call, containing all call artifacts including transcript, call ID, and recording URLs. ### 4. Use the Analytics API with Grouping The Analytics API allows you to filter and group data by `assistantId`: ``` curl --location 'https://api.vapi.ai/analytics' \ --header 'Content-Type: application/json' \ --header 'Authorization: Bearer YOUR_TOKEN' \ --data '{ "queries": [ { "name": "getAnalyticsByAssistantID", "table": "call", "timeRange": { "start": "2025-01-01T00:00:00Z", "end": "2025-03-21T23:59:59Z",

This is the function I have created to fetch the call logs file attached https://cdn.discordapp.com/attachments/1353426530801287209/1353428007062339664/fetchCallLogs.txt?ex=67e19d8e&is=67e04c0e&hm=e66f12b4c5943446dca10d5885ad225e4e544f6c56ebc962e088705dbfdde684&

Hey Hasan, There is no way to reduce the time it takes to get the API to get the call logs related to an assistant. Instead, what you can do from now on is store the call logs related to each call and the assistant using the end-of-call report server message or server event. This will help you reduce the time and get real-time updates. Like right after the end of the call, you will have the complete call data in your database. This will eventually solve your problem, but yes, once you have to use call logs API.
