User data change

There are various reasons why a user might request a data change, for example, moving to a new city, getting married and thus changing their name or adding a nationality. In order to keep the user information synchronised and up-to-date, the Investment API allows data changes by sending appropriate requests.

This guide outlines how to change data about a user and which proof documents have to be provided.

How user data changes work

In the request body, you specify which fields you intend to change.


Before you can change data of a user you must have created one. You can find out how to do this in our User onboarding guide.

Changing user data

To change data of a user, send

POST /users/{user_id}/data_change_requests

Example request

  "first_name": "Franz",
  "last_name": "Müller",
  "address": {
    "address_line1": "Rosenweg 222",
    "postcode": "45678",
    "city": "Berlin",
    "state": "BE",
    "country": "DE"

Next steps

Since a change to user data can made at any point in the user's lifecycle in the Investment API, a next step could be to create an account group or place an order. You can see the updated data when retrieving a report.
