Mandatory Tasks (DO NOT REMOVE)

• I have self-reviewed the code (A decent size PR without self-review might be rejected).
• I have updated the developer docs in /docs if this PR makes changes that would require a documentation change. If N/A, write N/A here and check the checkbox.
• I confirm automated tests are in place that prove my fix is effective or that my feature works.

How should this be tested?

1. create an event with hiding email and enabling phone number in the advanced tab
2. create an api key
3. Use api client and
   send this type of data :

{
  "start": "2026-07-21T10:00:00Z",
  "eventTypeId": 1157,
  "eventTypeSlug": "test-api-v2",
  "attendee": {
    "name": "Pro Example",
    "email": "pro23@example.com",
    "phoneNumber": "+919200000000",
    "timeZone": "Asia/Kolkata",
    "language": "en"
  },
  "guests": [],
  "location": {
    "type": "integration",
    "integration": "cal-video"
  },
  "metadata": {},
  "bookingFieldsResponses": {
    "customField": "customValue"
  }
}

with headers:

Authorization: <API_TOKEN>
cal-api-version: 2024-08-13
Content-Type: application/json

4. look at the response

• Are there environment variables that should be set?
• What are the minimal test data to have?
• What is expected (happy path) to have (input and output)?
• Any other important info that could help to test that PR

📝 Walkthrough

Walkthrough

The booking data handler was changed to copy reqBody.responses?.email into parsedBody.responses.email after schema.parseAsync(reqBody) when parsedBody.responses exists but its email field is missing. Tests were added covering two scenarios: (1) reqBody.responses.email present but omitted by the schema → resulting email comes from reqBody; (2) email hidden and absent from reqBody.responses → resulting email is undefined. Existing location extraction tests were left unchanged.

In `@packages/features/bookings/lib/handleNewBooking/getBookingData.ts`:
- Around line 27-30: The code in getBookingData.ts dereferences
reqBody.responses.email and parsedBody.responses.email without ensuring
responses exists; update the conditional to guard nested access (use
reqBody.responses?.email) and ensure parsedBody.responses is initialized before
assigning (e.g., if (reqBody.responses?.email && !parsedBody.responses?.email) {
parsedBody.responses = parsedBody.responses || {}; parsedBody.responses.email =
reqBody.responses.email; }) so accessing/setting email cannot throw; adjust the
conditional around reqBody and parsedBody in the getBookingData logic
accordingly.
