Resumable Upload API

This article demonstrates how to use the response object from generateFileResumableUploadUrl() to upload a file to a site's Media Manager.

Note: Due to limits on the size and duration of files that you can upload, we recommend using importFile(). See Wix Media: Supported Media File Types and File Sizes for more details.


This endpoint uses the uploadToken from the response for authorization. No additional authorization is needed.

Implement a Resumable Upload Client using TUS Protocol

In this example we use tus-js-client to implement a resumable upload using the TUS protocol.


async function resumableFileUpload(resumableUploadUrlResponse: GenerateFileResumableUploadUrlResponse): Upload {
// get the file content to upload
const fileName = 'imageExample.jpg';
const fileContent = await fs.createReadStream(path.join(__dirname, '..', 'files', fileName));
const mimeType = 'image/jpeg';
const params = {
filename: fileName,
contentType: mimeType,
token: resumableUploadUrlResponse.uploadToken
// Wrap the resumable upload session in a promise to wait for the upload to finish.
await new Promise(async (resolve, reject) => {
// Create a new TUS upload.
const upload = new tus.Upload(fileContent, {
// Use the uploadUrl from the response of the generate URL endpoint.
endpoint: resumableUploadUrlResponse.uploadUrl,
// Enable tus-js-client to automatically retry on errors.
retryDelays: [0, 3000, 5000, 10000, 20000],
// TSend parameters to the upload server to indentify the file and authentication token.
metadata: {
filename: fileName,
contentType: mimeType,
token: resumableUploadUrlResponse.uploadToken
// Callback for errors that can't be fixed using retries.
onError: function (error) {
console.log('Failed because: ' + error);
// Callback for reporting upload progress.
onProgress: function (bytesUploaded, bytesTotal) {
var percentage = (bytesUploaded / bytesTotal * 100).toFixed(2);
console.log(bytesUploaded, bytesTotal, percentage + '%');
// Callback for once the upload is completed.
onSuccess: function () {
console.log('Download %s from %s', fileName, upload.url);
// PUT request to finalize the upload.
// Note that we concatenate the URL and token of the resumable upload response.
const result = await httpClient.put(
{}, { params: { filename: fileName } }
