How do I generate a public-download URL for GCS?
Short answer: You can get signed url (public download) in Google Cloud Storage by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Google Cloud Storage Get Signed URL (Public Download) action to a workflow, map its 2 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

Every field can be mapped from an upstream trigger, AI step, table row, or hard-coded literal.

FAQ
Questions about Get Signed URL (Public Download).
What does the Get Signed URL (Public Download) action do in Google Cloud Storage?
Generates a time-limited URL that anyone can use to download the object without GCS auth. For "email the customer their export file" workflows that don't want to proxy bytes through the workflow runtime.
What inputs does Get Signed URL (Public Download) require?
Required: Bucket, Object Name. 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 Google Cloud Storage returns an error?
The run history shows the failed step with its input and the error message Google Cloud 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 Get Signed URL (Public Download) support batch operations?
Run Get Signed URL (Public Download) 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 Google Cloud Storage's rate limits.
