I am trying to use the following API endpoint:

> **[GET... - API documentation | SimplyBook.me Online Scheduling](https://simplybook.me/en/api/developer-api/tab/rest_api#method_GET_/admin/clients)**
>
> Clear and simple interface. Building your own booking service is easy peasy | See a full list of SimplyBook.me rich API options. We offer up to 200 different API functions.

to retrieve all clients whose email matches [weitao1116@gmail.com](mailto:weitao1116@gmail.com).

The request URL I used is:

[https://user-api-v2.simplybook.me/admin/clients?filter[email]=weitao1116@gmail.com](https://user-api-v2.simplybook.me/admin/clients?filter%5Bemail%5D=weitao1116@gmail.com)

However, it seems to return all clients, regardless of whether the email matches or not.

Did I use the API correctly? If not, what should I change?
