# Setting up the Oauth Client

For this tutorial we want to read the transactions on behalf of a end user. Te first thing we need to do is register a oauth client. There are 2 ways to do this and we'll dive into both of them. In this chapter we try to register the client and retrieve the client ID and Client Secret that belong to your oauth client.

## 1. Register oauth client as a bunq user

If you have access to a bunq account then it's fairly straight forward to set up an oauth client.

You can simply retrieve your oauth client ID and Secret from the bunq app. This is also the easiest way to set up a redirect URL (More on this later).

Another way is to register the client on the [Broken mention](broken://pages/glvIAX6lW191kCjCcygI).

End users will see your (business) name when they grant access to their bank account . That looks like this:

## 2. Register as a PSD2 user

In some cases you may not be a bunq user yourself but still want access to bunq user data. For instance when you're a PSD2-certified third-party provider (TPP), you can integrate directly with the bunq Public API using your **eIDAS certificate**.

This guide walks you through the step-by-step process to register and authenticate with the bunq environment.

This method to register a oauth client may not be applicable to you, if you're unsure refer to [PSD2](/psd2/are-you-a-third-party-provider-tpp-start-here.md). and [Are you a Third Party Provider (TPP)? Start here!](/psd2/are-you-a-third-party-provider-tpp-start-here.md)

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://doc.bunq.com/tutorials/access-end-user-acount-information-through-oauth/setting-up-the-oauth-client.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
