## OnceHub API: Generate One-time Booking Links with Hidden URL Parameters

[Section titled “OnceHub API: Generate One-time Booking Links with Hidden URL Parameters”](#oncehub-api-generate-one-time-booking-links-with-hidden-url-parameters)

You can now generate **short, one-time-use booking links** that pre-fill booking form fields and track UTM parameters — all **without exposing query parameters in the URL**.

With this enhancement, you can **keep the URL clean** while still passing form data and marketing attribution details securely in the background.

### How it works

[Section titled “How it works”](#how-it-works)

When you set the new`  hide_url_params  `field to` true` in your request, the API returns a **short, one-time-use link** that contains no visible query parameters.

* Form fields will still be prefilled based on the values passed in` booking_form`.
* UTM values passed in `utm_params` will be captured when the booking is made.

#### Example request

[Section titled “Example request”](#example-request)

```plaintext
JSON
{
  "hide_url_params": true,
  "utm_params":
  {
    "utm_source": "LinkedIn",
    "utm_medium": "ad_campaign",
    "utm_campaign": "product_launch",
    "utm_term": "automation_tools",
    "utm_content": "cta_button"
  },
  "booking_form": {
    "name": "Alex Johnson",
    "email": "alex.johnson@example.com",
    "Company": "BrightPath Consulting",
    "Job_Title": "Marketing Manager",
    "City": "London"
  }
}
```
