I’m working on an integration where a VAPI (Voice API) function returns the date and time in UTC format. However, when I use this timestamp to create events in Google Calendar via the Google Calendar API, the event times do not appear as expected. It seems that the times are not being interpreted correctly as UTC by the calendar, leading to incorrect event scheduling. What could be causing this discrepancy, and how can I ensure that the date and time are passed correctly to the Google Calendar API so that the events are scheduled at the right time in UTC?

@Subhashish Jung Shah It sounds like there may be an issue with how the date and time information is being formatted or communicated between the VAPI function and the Google Calendar API. Here are a few steps you can take to ensure that the date and time are passed correctly: 1. Check the Time Format: Ensure that the timestamp returned by the VAPI function is in the correct UTC format expected by the Google Calendar API. The format should be RFC3339, which looks like

YYYY-MM-DDTHH:MM:SSZ

for UTC times. 2. Specify the Time Zone: When creating events in Google Calendar, explicitly set the

timeZone

property to 'UTC' for both

start

and

end

times to make sure Google Calendar interprets the times as UTC. 3. Convert to Google Calendar Format: If necessary, convert the timestamp from the VAPI function to the RFC3339 format before sending it to the Google Calendar API. 4. Test with Static Data: Try creating an event with static UTC times to confirm that the issue is with the timestamp format or conversion. 5. Check the API Documentation: Review the Google Calendar API documentation to ensure that all required fields are being set correctly and that there are no additional settings that might affect time zone handling. 6. Log and Inspect API Requests: Log the API requests being made to the Google Calendar API and inspect them to ensure that the data being sent is in the correct format and that no unintended transformations are occurring. If you've already checked these aspects and the problem persists, it might be helpful to provide a specific example of the timestamp you're receiving from the VAPI function and how you're passing it to the Google Calendar API. This way, I can give you more targeted advice. If you need further assistance with the VAPI function itself or have other questions, please let me know!

@Subhashish Jung Shah you have to format the vapi response using llm in your server as of now there is no alternative to it because you have to provide the time zone current date and time to generate response in expected format.

I get the response in utc format as string and also change it to est TimeZone. Still i can’t schedule it correctly

hmm your doing on your server @Subhashish Jung Shah ?

Yes sir

@Subhashish Jung Shah idk when your going wrong, if you can brief in details then i can help better. THE COMPLETE PROCESS.
