I am working on a Laravel project and decided to use a Backblaze bucket as it's cheaper for storage when compared to AWS S3. I couldn't find a tutorial on how to get it working from scratch and I tested a bunch of Laravel B2 libraries that didn't end up working. The good news is that you don't need a special B2 plugin and instead can use the S3 package recommended by the Laravel docs.

If you haven't added the flysystem-aws-s3 package, add it to your project using composer:

Login to your B2 account and create your bucket with your required settings. Once created, you'll want to create a new application key with the permissions you need for your app. You should get a confirmation once it's generated:

Open your .env file and locate the settings for AWS. You'll need to add one key that's not there by default:

Match the settings in your .env from the application key to the values below.

Now you should be able to call the Laravel storage system like normal:
