How do I insert a row into a Supabase table?

Short answer: You can insert row in Supabase by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Supabase Insert Row 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.

FAQ

Questions about Insert Row.

What does the Insert Row action do in Supabase?

Inserts a new row into a Supabase table with the supplied field values. Respects table RLS policies based on the API key in use.

What inputs does Insert Row require?

Required: Table Name, Row Data (JSON). 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 Supabase returns an error?

The run history shows the failed step with its input and the error message Supabase 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 Insert Row support batch operations?

Run Insert Row 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 Supabase's rate limits.
