def create_api_integration(restApiId, resourcePath, httpMethod, integrationType, integrationHttpMethod,
                           uri, credentials, requestParameters=None, requestTemplates=None,

    '''
    Creates an integration for a given method in a given API.
    If integrationType is MOCK, uri and credential parameters will be ignored.

    uri is in the form of (substitute APIGATEWAY_REGION and LAMBDA_FUNC_ARN)
    "arn:aws:apigateway:APIGATEWAY_REGION:lambda:path/2015-03-31/functions/LAMBDA_FUNC_ARN/invocations"

    credentials is in the form of an iam role name or role arn.

    CLI Example:

    .. code-block:: bash

        salt myminion boto_apigateway.create_api_integration restApiId resourcePath httpMethod \\
                             integrationType integrationHttpMethod uri credentials ['{}' ['{}']]
