# How to Import Dictionary CSV

In order to import CSV file to dictionary user has to perform 2 steps:

1. Upload CSV file by ‘/api/v1/upload/dictionary-large’ endpoint using TUS client (<https://github.com/tus/tus-js-client>)

```
input.addEventListener("change", function(e) {
    // Get the selected file from the input element
    var file = e.target.files[0]

    // Create a new tus upload
    new tus.Upload(file, {
        endpoint: "http://localhost:8080/api/v1/upload/dictionary-large",
        retryDelays: [0, 3000, 5000, 10000, 20000],
        metadata: {
            filename: file.name,
            filetype: file.type
        },
        headers: {
            Dictionary: dictionaryUuid,
            Mailbox: mailboxUuid,
            Authorization: Bearer ...
        },
        onError: function(error) {
            console.log("Failed because: " + error)
        },
        onProgress: function(bytesUploaded, bytesTotal) {
            var percentage = (bytesUploaded / bytesTotal * 100).toFixed(2)
            console.log(bytesUploaded, bytesTotal, percentage + "%")
        },
        onSuccess: function() {
            console.log("Download %s from %s", upload.file.name, upload.url)
        },
        onAfterResponse: async (req: HttpRequest, res: HttpResponse) => {
            if (res.getHeader('Task')) {
              taskUuid = res.getHeader('Task');
            }
        }
    }).start();
})
```

2. Approve import processing task by endpoint ‘/api/v1/upload/{taskUuid}/confirm’ with following parameters:

headerFirstRow: boolean - if headers are in the first row of CSV filereplace: boolean - clear current records before import
