Code Examples

The example implementations below may be helpful when performing certain API operations.

File Uploads

Consider using the following code examples when uploading files.

Generate the upload checksum

Generating the checksum is required before uploading a file.

TypeScript

import { createSHA256 } from "hash-wasm";

export const generateSHA256Checksum = async (file: File) => {
    const sha256 = await createSHA256();
    const chunkSize = 10 * 1024 * 1024; // 10 MB
    const fileSize = file.size;
    for (let offset = 0; offset < fileSize; offset += chunkSize) {
        const chunk = file.slice(offset, offset + chunkSize);
        const buffer = await chunk.arrayBuffer();
        sha256.update(new Uint8Array(buffer));
    }
    const hashBuffer = sha256.digest("binary");
    return btoa(String.fromCharCode.apply(null, Array.from(hashBuffer)));
}

Python

import hashlib
import base64
from pathlib import Path

def generate_sha256_checksum(file_path: Path) -> str:
    with file_path.open("rb") as f:
        hash_digest = hashlib.file_digest(f, "sha256").digest()
    return base64.b64encode(hash_digest).decode('utf-8')

Encode the file name

The encoded file name is required when uploading a file.

TypeScript

const encodedFileName = encodeURIComponent("file_name123%€.wav")

Python

import urllib.parse

encoded_file_name = urllib.parse.quote("file_name123%€.wav", safe="-.!~*'()")
