# Set up an integration request in API Gateway
<a name="api-gateway-integration-settings-integration-request"></a>

To set up an integration request, you perform the following required and optional tasks:

1.  Choose an integration type that determines how method request data is passed to the backend.

1.  For non-mock integrations, specify an HTTP method and the URI of the targeted integration endpoint, except for the `MOCK` integration.

1.  For integrations with Lambda functions and other Amazon service actions, set an IAM role with required permissions for API Gateway to call the backend on your behalf.

1.  For non-proxy integrations, set necessary parameter mappings to map predefined method request parameters to appropriate integration request parameters.

1.  For non-proxy integrations, set necessary body mappings to map the incoming method request body of a given content type according to the specified mapping template.

1.  For non-proxy integrations, specify the condition under which the incoming method request data is passed through to the backend as-is. 

1.  Optionally, specify how to handle type conversion for a binary payload.

1.  Optionally, declare a cache namespace name and cache key parameters to enable API caching. 

 Performing these tasks involves creating an [Integration](https://docs.amazonaws.cn/apigateway/latest/api/API_Integration.html) resource of API Gateway and setting appropriate property values. You can do so using the API Gateway console, Amazon CLI commands, an Amazon SDK, or the API Gateway REST API.
