Upload

Overview

Twitter allows developers to upload files on their servers so that they can be used in tweets. Twitter has a limited file format that they support:

• Images : PNG, JPEG, WEBP and GIF. Animated GIFs are supported.
• Videos : MP4

If you want to learn more about the supported formats and video recommendations visit Twitter upload documentation.

Let's code

Tweetinvi offers various solution to upload files on Twitter. A successful upload will create an IMedia that can be attached to a tweet publication.

Upload Images

var image = File.ReadAllBytes("path");
var media = Upload.UploadImage(image);

Upload Videos

IMPORTANT : Videos can only be published using the chunked upload endpoint.

var video = File.ReadAllBytes("path");
var media = Upload.UploadVideo(video);

Chunked Uploads

Chunked upload allows developer to upload videos but it more specifically allow developers to upload any binary in multiple steps.

For phone app developers such a feature can be incredibly useful as you will no longer have to wait for an entire file to be uploaded at once.

var uploader = Upload.CreateChunkedUploader();

// Initialize the upload
var initSucceeded = uploader.Init("video/mp4", totalBinaryLength);

// Upload your different chunks
var success1 = uploader.Append(firstChunk);

if (!success1) 
{
     RetryUpload(uploader, firstChunk);
}

var success2 = uploader.Append(secondChunk);

// When you have uploaded all your chunks
var media = uploader.Complete();
