# GetResponse credentials

You can use these credentials to authenticate the following nodes:

* [GetResponse](/integrations/builtin/app-nodes/n8n-nodes-base.getresponse.md)
* [GetResponse Trigger](/integrations/builtin/trigger-nodes/n8n-nodes-base.getresponsetrigger.md)

## Prerequisites <a href="#prerequisites" id="prerequisites"></a>

Create a [GetResponse](https://www.getresponse.com/) account.

## Supported authentication methods <a href="#supported-authentication-methods" id="supported-authentication-methods"></a>

* API key
* OAuth2

## Related resources <a href="#related-resources" id="related-resources"></a>

Refer to [GetResponse's API documentation](https://apidocs.getresponse.com/v3) for more information about the service.

## Using API key <a href="#using-api-key" id="using-api-key"></a>

To configure this credential, you'll need:

* An **API Key**: To view or generate an API key, go to **Integrations and API > API**. Refer to the [GetResponse Help Center](https://www.getresponse.com/help/where-do-i-find-the-api-key.html) for more detailed instructions.

## Using OAuth2 <a href="#using-oauth2" id="using-oauth2"></a>

To configure this credential, you'll need:

* A **Client ID**: Generated when you [register your application](https://apidocs.getresponse.com/v3/authentication/oauth2).
* A **Client Secret**: Generated when you [register your application](https://apidocs.getresponse.com/v3/authentication/oauth2) as the **Client Secret Key**.

When you register your application, copy the **OAuth Redirect URL** from n8n and add it as the **Redirect URL** in GetResponse.

{% hint style="info" %}
**Redirect URL with localhost**

The Redirect URL should be a URL in your domain, for example: `https://mytemplatemaker.example.com/gr_callback`. GetResponse doesn't accept a localhost callback URL. Refer to the [FAQs](#configure-oauth2-credentials-for-a-local-environment) to configure the credentials for the local environment.

## Configure OAuth2 credentials for a local environment <a href="#configure-oauth2-credentials-for-a-local-environment" id="configure-oauth2-credentials-for-a-local-environment"></a>

GetResponse doesn't accept the localhost callback URL. Follow the steps below to configure the OAuth credentials for a local environment:

1. Use [ngrok](https://ngrok.com/) to expose the local server running on port `5678` to the internet. In your terminal, run the following command:

```sh
ngrok http 5678
```

2. Run the following command in a new terminal. Replace `<YOUR-NGROK-URL>` with the URL that you got from the previous step.

```sh
export WEBHOOK_URL=<YOUR-NGROK-URL>
```

3. Follow the [Using OAuth2](#using-oauth2) instructions to configure your credentials, using this URL as your **Redirect URL**.
