Apigateway support for direct pinpoint SendOTPMessage operation

I try integrating apigateway with aws pinpoint service from console to make a call to SendOTPMessage. I configure a iam role with de permissions mobiletargeting:SendOTPMessage and mobiletargeting:VerifyOTPMessage then attached to de integration. But whe calling the integration recive this response. { "message": "AWS Service of type mobiletargeting not supported", "code": "BadRequestException", "time": "2023-01-10T00:19:48.534Z", "requestId": "d3e13531-7075-4046-b219-a852fe74ca9b", "statusCode": 400, "retryable": false, "retryDelay": 47.67913168464831, "fatal": true }

apigateway rest api don't support pinpoint? or only don't support this operation. ?
