Gate CFD API Update: mt5_uid Field Removal from Selected Endpoints

To further optimize the response structure of CFD APIs, Gate will remove the mt5_uid field from the responses of selected CFD APIv4 endpoints. After the change takes effect, these endpoints will no longer return this field. Please complete any necessary adaptations as soon as possible to avoid disruptions caused by the missing field.

1.Affected APIs

• POST /tradfi/users (Create CFD user)

• GET /tradfi/users/mt5-account (Query MT5 account information)

• GET /tradfi/users/assets (Query account assets)

2.Removed Field

The following field will be removed from the API responses above:

mt5_uid

• Description: MT5 user ID

• Change: The field will no longer be included in successful responses

3.Impact Notes

• This change only removes the response field mt5_uid . Endpoint paths, request methods, and other response fields remain unchanged

• If your client performs strict response validation (e.g., requiring mt5_uid to be present) or relies on this field for business logic, please adjust such dependencies in advance

• All other endpoint capabilities remain unchanged; please refer to the latest API documentation for field definitions
