If you saved that in your app you already have a reference to who your user is. The most important item to keep track of is the userid. As that's what we'll need in the next few steps. #### What we have done so far * We have created a sandbox user, and generated an API key * We have created a installation and registered a device * We generated a session and now know the user ID and Session token In the next chapter we'll use these to make our API calls ## Who is my user, and what is his current balance? To retrieve our user we simply can do a API call to the user endpoint and this will return us our current user. We already had this information from the previous step. The important thing to save here is the user ID. We'll need to pass it as a url parameter in the next calls. {% openapi src="" path="/user" method="get" %} {% endopenapi %} ## So, what is the balance of our user? We'll we need just one more step that is to call the monetary-account-bank endpoint. This endpoint lists all monetary accounts we know for this user. The response contains a list of monetary accounts. Take note of the monetary account ID, most of the API calls reference both the user ID as well as the ID of the thing you are performing your actions on. To answer the question: what is the balance of our user. You can see that the newly created user comes with 1 monetary account, with a balance of €0.00. Let's add some money to the account! ```json "Response": [ { "MonetaryAccountBank": { "id": 2026814, "created": "2025-03-05 16:12:01.255073", "updated": "2025-03-05 16:12:01.255073", ... more key value pairs ... } "balance": { "currency": "EUR", "value": "0.00" }, } ] ``` {% openapi src="" path="/user/{userID}/monetary-account-bank" method="get" %} {% endopenapi %} --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://doc.bunq.com/tutorials/your-first-payment/setting-up-a-sandbox-user/retrieving-my-user-details.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
