# Single call integrations

Single call \(single page\) integration scripts are the simplest types of integrations. They require one call, often to an external source of data, to retrieve data. Only retrieveData\(\) is required to be implemented for single page/single call integrations.

A sample that demonstrates a simple single call integration script follows. It creates a RESTMessageV2 and executes it. It then returns an object using the response body as the contents, along with an assumed contentType and extension.
