WORKFLOW ACTIONS
What you can configure.
Choose an action in the workflow builder, connect an account, and map its inputs. These actions are available in the catalog; your account access and a successful test determine whether they work for your setup.
Create row
Write
Insert one typed JSON row into a Supabase table.
Permissions and limits
Account permissions
INSERT and SELECT on the exposed table
Operation limits
Returns the provider-confirmed inserted row. A lost response remains uncertain and is not retried.
A repeated request may repeat the external action. Review the previous result before retrying a write.
Delete row
Write
Delete one row matching a named unique column in a Supabase table.
Permissions and limits
Account permissions
DELETE and SELECT on the exposed table
Operation limits
PostgREST rejects a deletion affecting more than one row. A lost response remains uncertain and is not retried.
A repeated request may repeat the external action. Review the previous result before retrying a write.
Get Auth user
Read
Read selected identity and sign-in timestamps for one Auth user.
Permissions and limits
Account permissions
Supabase service role access to Auth users
Operation limits
Only selected Auth user identity fields are returned. Metadata, identities, provider tokens and full account records are excluded from workflow results.
Get row
Read
Read one row matching a named unique column in a Supabase table.
Permissions and limits
Account permissions
SELECT on the exposed table
Operation limits
Use a unique or primary-key column. Two matching rows cause an error rather than an arbitrary first result.
Invite Auth user
Write
Send one Auth invite email through the selected Supabase project.
Permissions and limits
Account permissions
Supabase service role access to invite Auth users
Operation limits
This sends a real email. A timed-out write can have succeeded, so NodeHub does not retry it automatically.
Only a provider-confirmed user receipt is returned.
A repeated request may repeat the external action. Review the previous result before retrying a write.
List Auth users
Read
Read one bounded page of users from the selected project's Auth directory.
Permissions and limits
Account permissions
Supabase service role access to Auth users
Operation limits
One page of at most 100 users is returned.
Only selected Auth user identity fields are returned. Metadata, identities, provider tokens and full account records are excluded from workflow results.

Permissions and limits
Account permissions
SELECT on the exposed table
Operation limits
Up to ten AND filters, three OR groups of at most five alternatives each, and three order columns, with a page of at most 1,000 rows. Nested Boolean expressions and raw PostgREST syntax are not accepted.
Secret or service-role keys can bypass RLS. Grant this connection only to trusted workspace members.
Pagination: offset. Check the result for additional pages; a single action may not return every record.
Update row
Write
Update one row matching a named unique column in a Supabase table.
Permissions and limits
Account permissions
UPDATE and SELECT on the exposed table
Operation limits
PostgREST rejects an update affecting more than one row. A lost response remains uncertain and is not retried.
A repeated request may repeat the external action. Review the previous result before retrying a write.
SETUP
Start with a controlled test.
01Connect the intended account
Use the account and permissions required for your process. Review the connection check before configuring a workflow action.
02Review inputs and access
Select a listed operation and map its required inputs. Use test records and add a human approval before writes that need review.
03Confirm the result
Inspect step outputs and confirm the result in Supabase. A saved workflow is not a completed provider action.
