# Cybersource
> Learn how to connect Cybersource to Slicker
### Prerequisites
Slicker integrates with Cybersource via their REST API. Credentials for this API are created via Cybersource's Business Center.
### Create credentials
Follow the [official Cybersource documentation for creating a Shared Secret Key](https://developer.cybersource.com/docs/cybs/en-us/platform/developer/all/rest/rest-getting-started/restgs-jwt-shared-secret-intro/restgs-shared-secret-create-intro/restgs-shared-secret-create-task.html).
In the end you will need to have the following:
* Merchant ID
* Key ID
* Secret Key
### Create integration in Slicker
1. Go to Slicker's [new integration page](https://app.slickerhq.com/integrations/new).
2. Select `Cybersource` from the list of integrations.
3. Give the integration a name and description to help you identify it later.
4. Enter the Merchant ID, Key ID, and Secret Key generated from the Business Center.
5. Click the `Submit` button to create the integration.
### Troubleshooting
On integration creation, Slicker will attempt to connect to Cybersource using the provided credentials.
If the connection fails, you will see an error message like the one below.
Please double-check the provided credentials, make sure they have the correct permissions, and try again.
