Over the years on snapchat I have saved lots of photos that I would like to retrieve now, The problem is they do not make it easy to export, but luckily if you go online you can request all the data (thats great)

I can see all my photos download link and using the local HTML file if I click download it starts downloading.

Here's where the tricky part is, I have around 15,000 downloads I need to do and manually clicking each individual one will take ages, I've tried extracting all of the links through the download button and this creates lots of Urls (Great) but the problem is, if you past the url into the browser then ("Error: HTTP method GET is not supported by this URL") appears.

I've tried a multitude of different chrome extensions and none of them show the actually download, just the HTML which is on the left-hand side.

The download button is a clickable link that just starts the download in the tab. It belongs under Href A

I'm trying to figure out what the best way of bulk downloading each of these individual files is.

So, I just watched their code by downloading my own memories. They use a custom JavaScript function to download your data (a POST request with ID's in the body).

You can replicate this request, but you can also just use their method. Open your console and use downloadMemories(<url>)

Or if you don't have the urls you can retrieve them yourself:

var links = document.getElementsByTagName("table")[0].getElementsByTagName("a");
eval(links[0].href);

UPDATE

I made a script for this:

Using the .json file you can download them one by one with python:

req = requests.post(url, allow_redirects=True)
response = req.text
file = requests.get(response)

Then get the correct extension and the date:

day = date.split(" ")[0]
time = date.split(" ")[1].replace(':', '-')
filename = f'memories/{day}_{time}.mp4' if type == 'VIDEO' else f'memories/{day}_{time}.jpg'

And then write it to file:

with open(filename, 'wb') as f: f.write(file.content)

I've made a bot to download all memories.

You can download it here

It doesn't require any additional installation, just place the memories_history.json file in the same directory and run it. It skips the files that have already been downloaded.

Short answer

Download a desktop application that automates this process.

Visit downloadmysnapchatmemories.com to download the app. You can watch this tutorial guiding you through the entire process.

In short, the app reads the memories_history.json file provided by Snapchat and downloads each of the memories to your computer.

Long answer (How the app described above works)

We can iterate over each of the memories within the memories_history.json file found in your data download from Snapchat.

For each memory, we make a POST request to the URL stored as the memories Download Link. The response will be a URL to the file itself.

Then, we can make a GET request to the returned URL to retrieve the file.

Example

Here is a simplified example of fetching and downloading a single memory using NodeJS:

Let's say we have the following memory stored in fakeMemory.json:

{ "Date": "2022-01-26 12:00:00 UTC", "Media Type": "Image", "Download Link": ""
}

We can do the following:

// import required libraries
const fetch = require('node-fetch'); // Needed for making fetch requests
const fs = require('fs'); // Needed for writing to filesystem
const memory = JSON.parse(fs.readFileSync('fakeMemory.json'));
const response = await fetch(memory['Download Link'], { method: 'POST' });
const url = await response.text(); // returns URL to file
// We can now use the `url` to download the file.
const download = await fetch(url, { method: 'GET' });
const fileName = 'memory.jpg'; // file name we want this saved as
const fileData = download.body; // contents of the file
// Write the contents of the file to this computer using Node's file system
const fileStream = fs.createWriteStream(fileName);
fileData.pipe(fileStream);
fileStream.on('finish', () => { console.log('memory successfully downloaded as memory.jpg');
});
