<a name="manually-testing-connector"></a>

To manually test your C2C connector end-to-end, you must simulate both the customer and the end user.

**You will need the following resources:**
+ An AWS Lambda ARN designating the connector you would like to test.
+ A testing OAuth 2.0 user account from your cloud platform.
+ A connector registered with managed integrations for AWS IoT Device Management. For more information, see [Use a C2C (Cloud-to-Cloud) connector](use-c2c-create-cloud-connector.md).
