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 run history shows the failed step with its input and the error message Azure Blob Storage returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.

Does Upload Blob support batch operations?

Run Upload Blob inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within Azure Blob Storage's rate limits.
