Documented steps
Deploy an Edge Function first (see 'Deploy a Supabase Edge Function with the Supabase CLI').
Invoke via curl: POST https://<project-ref>.supabase.co/functions/v1/<function-name> with headers 'apikey: <PUBLISHABLE_KEY>' and 'Content-Type: application/json' and a JSON body.
Or via supabase-js: call createClient(url, publishableKey) then await supabase.functions.invoke('name', { body: {...} }).
The function handler reads the request (including its JSON body) and returns a Response; the response body comes back to the caller.
Verify the live response reflects the deployed version.

Known gotchas
You must send an 'apikey' header (publishable/anon key works for most functions; the function template also validates secret keys).
Configure CORS if you invoke from a browser/JavaScript app - functions have specific CORS guidance.
The function URL uses your project ref: https://<project-ref>.supabase.co/functions/v1/<name>.
Functions have execution time/memory limits and can cold-start; design for short-lived idempotent operations.
