# How to create an OAuth app in Mollie

## Before you start, you’ll need:

- A Mollie account ([you can create one here](https://my.mollie.com/dashboard/signup?lang=en)). 

- Your OAuth redirect URI: __https://unify.apideck.com/vault/callback__

- A Client ID and Client Secret. When you register to authenticate with OAuth 2.0, we return to you a Client ID and Client Secret for your application to authenticate with the Mollie API.

## Register and authenticate your OAuth application

You can register the app in [your Mollie Dashboard](https://www.mollie.com/dashboard/developers/applications). You will receive a Client ID and Client Secret, both of which should be kept secret.

These credentials can be used inside Apideck to use your OAuth application with custom credentials.

## Do your first API call

- Connect your Mollie account through [Vault](https://platform.apideck.com/vault) with a test session.

- To test the access token, make a call to the [`List orders`](https://docs.mollie.com/reference/v2/orders-api/list-orders) endpoint using the [Proxy API](https://developers.apideck.com/apis/proxy/reference).

```
curl --location --request GET 'https://unify.apideck.com/proxy' \
--header 'x-apideck-consumer-id: test-consumer' \
--header 'x-apideck-app-id: {APIDECK_APP_ID}' \
--header 'x-apideck-service-id: mollie' \
--header 'x-apideck-downstream-url: https://api.mollie.com/v2/orders' \
--header 'Authorization: Bearer {APIDECK_API_KEY}'
```
