## How to fetch the data for this report template

You will need to run a crawl for report template to generate report. When report has been generated and you have
crawl id you can fetch data for the report using the following query:


```graphql
query GetReportStatForCrawl(
      $crawlId: ObjectID!
      $reportTemplateCode: String!
      $after: String
     ) {
        getReportStat(
          input: {crawlId: $crawlId, reportTemplateCode: $reportTemplateCode}
        ) {
          crawlLinks(after: $after, reportType: Basic) {
            nodes {
              urlTo
              urlToTitle
              relUrlFrom
              urlFrom
              urlFromTitle
              urlToDeeprank
              hreflangLanguage
              hreflang
              urlToIdentifiedLanguage
            }
            totalCount
            pageInfo {
              endCursor
              hasNextPage
            }
          }
       }
     }
```
