Hello, This sounds like a classic timezone serialization issue during webhook handoff, and I’ve fixed similar problems involving VAPI, n8n, and calendar integrations where everything works independently but shifts during the transfer. I’ll trace the full date-time lifecycle—from how VAPI generates and sends the timestamp, through the webhook payload, to how n8n parses and writes the event—checking for timezone offsets, ISO-8601 formatting differences, UTC vs local conversions, and node-level parsing behavior. If needed, I’ll implement a clean fix using proper timezone normalization, either at the VAPI webhook level, inside n8n node settings, or with a lightweight conversion step to ensure consistent scheduling. What I’ll deliver: • Corrected n8n workflow or VAPI webhook configuration (export file included) • Reliable event creation with accurate timezone handling • Clear explanation of the root cause and exact fix applied • Tested using real call flow to ensure consistent results I’ve worked with webhook-based AI and automation pipelines, and I know how subtle timezone mismatches can be—especially between systems defaulting to UTC vs local time. Quick question: which calendar provider are you using (Google Calendar, Outlook, or other)? I’m ready to access your workflows and resolve this today. Best regards, Dimitar

@amirmujtaba92786

Hi I understand your problem of mismatched timing of Vapi and n8n. I can help you to fix this issue. Let's connect for more details, thank you. Best regards Amir

@FizzaNadeemK

Hi I’ll trace the date time hand off between VAPI and n8n and fix the timezone or format mismatch so bookings land in the right slots. The issue only appears at the webhook boundary, so I’ll inspect the VAPI payload, the n8n node settings, and how the calendar expects timestamps. I’ll add a clean conversion step if needed and test with real calls until the hour is consistent every time. You’ll get the updated VAPI or n8n export with the fix applied and ready to redeploy. I’ve debugged webhook driven booking flows where everything worked in isolation but broke at integration points. A common risk is mixed UTC and local time handling, so I’ll normalize timezones end to end. If you share access, I can patch this today and confirm with live tests.

@Swatintf

Hi Client, I really like this project — especially because it’s not about starting from scratch, but about taking AI-generated concepts and giving them the professional polish they deserve. For a traditional UK lock manufacturer, the logo needs to communicate strength, trust, and heritage. Small refinements in typography, spacing, and proportion can completely elevate how established the brand feels — especially when it’s going live across social platforms and possibly print. My approach would be: • Carefully refine the chosen logo concept (kerning, balance, alignment, colour confidence) • Build a simple but consistent visual system (fonts, spacing, layout rules) • Design a clean, screen-optimised brochure that feels professional and structured • Create a well-organised one-page technical data sheet with clear hierarchy • Develop a bold, mobile-friendly social flyer that stands out without feeling cluttered I understand how important it is for all materials to feel cohesive from the first social post to the brochure download — especially for a brand built around reliability and security. I’d be happy to share relevant work and outline a realistic timeline once we connect. Looking forward to refining this into a launch-ready identity you can confidently stand behind.

@usamaansari786

Hi there, I will fix your VAPI to n8n calendar mismatch immediately to ensure every booking lands in the correct time slot. Since the hand-off is failing, I will focus on ISO 8601 normalization and UTC to Local conversion within your n8n workflow. I’ll audit your VAPI tool-call payload and implement a robust date formatter node in your self hosted n8n instance to eliminate the "wrong slot" error today. I will provide the updated workflow export and a clear maintenance note so your voice AI remains perfectly synced with your calendar. I have some awesome portfolios available on request. Q) Is VAPI currently sending the date as a raw ISO string (UTC), or is the LLM attempting to pass a "human-readable" time that n8n is misinterpreting based on your server's local time? I am ready to start the trace and patch this for you right now. Please share your VAPI and n8n access so I can begin the fix! Best Regards, Usama F

@huzaifa306

Hi, I have solid experience working with both VAPI and self hosted n8n, including calendar automations and time zone handling. I can trace the date time payload from VAPI to n8n, identify where the mismatch occurs, and implement the correct conversion or webhook adjustment so bookings land in the right slot consistently. I will test with real calls, provide the updated workflow export, and include a clear note explaining the fix. I am ready to patch this today.

@ujjawalnagar

I can fix this for you today. This VAPI to n8n date-time mismatch is a common issue I've solved multiple times. As the Senior AI Developer for a Dubai agency, my core responsibility was building and debugging lead qualification voice agents using VAPI and n8n as our primary tools. The hand-off between these two systems, especially with time zones, is an area I know intimately. My Immediate Diagnostic Plan: Trace the Payload: I will first examine the webhook payload VAPI sends to n8n to see the exact date-time format and timezone information being passed. Inspect n8n Ingestion: I'll check how the n8n webhook node is receiving and interpreting that data. Implement the Fix: The solution is typically one of three things: Adjusting the timezone setting directly in the n8n date/time node. Adding a simple Function node to parse and reformat the date string correctly. Ensuring the final calendar event creation uses the correct UTC offset. There's no need for guesswork. I will pinpoint the data formatting error between the systems, apply the fix, and run a live test call to confirm the calendar event books in the correct slot. You'll receive the updated workflow and a clear explanation of the change. Let's get this patched.

@TheDeveloper10

Hi, You’re looking to fix the time-slot mismatch between your VAPI voice AI receptionist and n8n calendar workflow, and I can help you implement this efficiently and cleanly. Here’s my approach: First, I’ll trace the full hand-off path from VAPI to n8n, inspecting how date-time values are passed, including time zones and formatting. Then, I’ll identify where the mismatch occurs—whether in the webhook payload, n8n node parsing, or conversion logic—and apply a precise fix, which may involve adjusting VAPI webhook settings, n8n node configurations, or adding a small conversion step to ensure correct time slots. Finally, I’ll test with real calls to confirm that all events land in the correct calendar slots, export the updated workflows, and provide a brief note documenting the change for future maintenance. To proceed, could you clarify: Are all events in a single time zone, or do you need multi-time-zone support? I have hands-on experience debugging VAPI ↔ n8n integrations and resolving similar automation timing issues. Let’s get your calendar booking accurate and reliable today.

@Hemantt841

You’re looking to fix the scheduling sync issue where your voice AI receptionist built on VAPI hands off calendar bookings to n8n, but events land in incorrect time slots due to a mismatch at the hand-off. I understand you need someone to trace the date-time data flow between VAPI and n8n, identify the root cause, and apply a fix by adjusting the webhook, n8n node settings, or adding a timezone conversion step. With over 15 years of experience and 200+ projects completed, I specialize in PHP, API integrations, automation with n8n, and database work using MySQL. I’ve worked extensively on similar voice AI and workflow automation systems, ensuring seamless data transfer and accurate scheduling across platforms. I will start by reviewing your existing VAPI flow and n8n self-hosted workflow to replicate the issue with real calls. Then, I’ll analyze the date-time handling between both systems, make the necessary adjustments, and test until the events consistently land in the correct time slots. I’ll deliver the updated workflow export along with a clear explanation of the changes within a day. Feel free to share access so we can get this fixed promptly and keep your scheduling running smoothly.

@danielboggs

Hello, there, I’ve gone through your description and it’s clear the issue sits right at the VAPI→n8n hand‑off, likely where the date-time payload gets transformed or interpreted differently across the two systems. I’ve worked extensively with LLM-driven voice interfaces, webhook-based integrations, and custom automation pipelines, and I’m comfortable tracing how timestamps move through each step, whether that’s a VAPI JSON payload, an n8n Set node, or a conversion inside a Function node. If you grant access, I can walk the full pipeline, log the raw values, compare them against what n8n receives, and apply a clean fix, often it comes down to aligning UTC offsets or adjusting how n8n parses the incoming format. I’ll update the workflow export and leave a concise explanation so you can maintain it later. Once the booking consistently lands in the right hour, we’ll wrap things up. Could you confirm whether VAPI is sending timestamps in UTC or in the caller’s local time zone? Best regards, Daniel
