How do I upload a file to Azure Blob Storage?

Short answer: You can upload blob in Azure Blob Storage by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Azure Blob Storage Upload Blob action to a workflow, map its 4 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ

Questions about Upload Blob.

What does the Upload Blob action do in Azure Blob Storage?

Uploads a blob from base64 content, text, or fetched URL with content-type and custom metadata. For files >100MB, the simple-shot upload caps out — use block-blob multipart uploads via HTTP action for larger files.

What inputs does Upload Blob require?

Required: Container, Blob Name (path), File content (URL or raw bytes). Every input accepts a static value or a variable from any upstream node in your workflow.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if Azure Blob Storage returns an error?

The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.

Does Upload Blob support batch operations?

Yes. Run Upload Blob inside a Loop node to process arrays. TinyCommand handles Azure Blob Storage's rate limits automatically so you don't have to throttle manually.

Removes a specific blob from a container. Irreversible. For workflows that need to clean up temporary blobs after processing (transcoded video files, scrap downloads, expired exports), this is the cleanup action.
