Save every generated PDF to Backblaze B2
DocSpring's S3 integration works with Backblaze B2's S3-compatible API. Every PDF it generates is copied into your B2 bucket, a low-cost archive of every document.
What you can do with Backblaze B2
Uploads
- Every PDF, automatically
- Each PDF is uploaded as soon as it's generated, including combined PDFs.
- Your own file paths
- Build each path from the template, the date, and your own metadata, for example a folder for each client.
- Choose which PDFs
- Upload live PDFs, test PDFs or both, and limit uploads to specific API tokens.
Access and status
- A B2 application key
- Connect with an application key that can write to your bucket.
- Upload status and alerts
- Each PDF shows whether its upload is done or failed, and DocSpring emails you if uploads keep failing.
Set up the Backblaze B2 integration
Read the setup guide- In Backblaze, create an application key that can write to your bucket, and copy its key ID and key.
- In DocSpring, open Integrations, choose Set up Backblaze B2, and enter your bucket's S3 endpoint, its name and the application key.
- Set the file path and choose which PDFs to upload.
