Create Signed URL (Supabase)

Use this action to generate a temporary link to a file in Supabase Storage.

Add the action

1. Create (or open) an Interface workflow.
2. Click + Add action.
3. Select Supabase → Create Signed URL.
4. Select the Supabase Connection you want to use.

Configure the action

• Bucket — The bucket that contains the file.
• Path — File path inside the bucket.
• Expires in (seconds) — How long the link should stay valid (for example 3600 for 1 hour).

Image transformation (optional)

If you’re generating a link to an image, you can optionally resize it:

• Width
• Height
• Resize mode — Cover, Contain, Fill, or none.
• Quality — 20–100

Common pitfalls

The link expires too fast

Increase Expires in (seconds), or generate a new signed URL when the user needs it.

CONTINUE LEARNING

If the bucket is public, you may not need a signed URL.
