Supabase

Add, get, delete, and update rows in Supabase tables.

Overview

Supabase is an open-source Backend-as-a-Service (BaaS) built on top of PostgreSQL. This tool interacts with Supabase tables through the PostgREST REST API to create, read, update, and delete rows. It supports PostgREST filtering operators (eq, neq, gt, lt, gte, lte, like, ilike, is, fullText), custom database schemas, auto-mapping of input data to table columns, and pagination for large result sets. The Service Role key is used for authentication, which bypasses Row Level Security (RLS).

All Operations

Parameter	Type	Required	Default	Description
Use Custom Schema	boolean	No	false	Whether to use a database schema different from the default “public” schema. Requires schema exposure in the Supabase API settings.
Schema	string	No	public	Name of the database schema to use for the table. (shown when Use Custom Schema is true)
Max Concurrency	number	No	10	Maximum number of items to process concurrently. Accepts 1–100.

Output Data

Every operation returns the affected rows, and each returned row becomes its own output item — the row IS the item JSON, with no wrapper property. That means one input item can produce many output items: a Get Many that matches 200 rows produces 200 items, and a Delete whose conditions match 40 rows produces 40 items. The input item’s JSON does not pass through; binary data on the input item is forwarded to every item it produces.

Operation	Output items per input item	Item JSON
create	One	The created row exactly as the table stores it, including database defaults and generated keys
delete	One per deleted row	Each row as it looked before deletion
get	One per matching row	The matched row. Despite the name, the equality conditions can match more than one row — add enough conditions to identify a single row
getAll	One per row	The row. With Return All on, the node pages through the table and emits every row it finds
update	One per updated row	Each row after the update was applied

When the request succeeds but matches nothing, a single item with an empty JSON object is emitted so the branch still carries an item. If the service replies with something that is not an object, the value is wrapped as { "data": … }.

Reference the result downstream by expression, e.g. {{ $json.id }} or {{ $json.email }}.

Usage Examples

• Insert a new user row into a Supabase users table
• Fetch all orders from Supabase with status=active filter
• Update a customer record in Supabase by email
• Delete rows from Supabase where age is greater than 100
• Get all products from a custom schema in Supabase

Example Configuration

Create a row by auto-mapping the incoming item, skipping two internal properties:

{
  "type": "supabase",
  "parameters": {
    "resource": "row",
    "operation": "create",
    "tableId": "users",
    "dataToSend": "autoMapInputData",
    "inputsToIgnore": "internal_id,created_at"
  }
}

Create a row from explicitly defined column values:

{
  "type": "supabase",
  "parameters": {
    "resource": "row",
    "operation": "create",
    "tableId": "products",
    "dataToSend": "defineBelow",
    "fieldsUi": {
      "fieldValues": [
        { "fieldId": "name", "fieldValue": "New Product" },
        { "fieldId": "price", "fieldValue": "29.99" },
        { "fieldId": "category", "fieldValue": "electronics" }
      ]
    }
  }
}

Update the rows that match two conditions at once:

{
  "type": "supabase",
  "parameters": {
    "resource": "row",
    "operation": "update",
    "tableId": "users",
    "dataToSend": "autoMapInputData",
    "filterType": "manual",
    "matchType": "allFilters",
    "filters": {
      "conditions": [
        { "keyName": "id", "condition": "eq", "keyValue": "123" },
        { "keyName": "status", "condition": "eq", "keyValue": "active" }
      ]
    }
  }
}

Delete old debug logs with a raw PostgREST filter string:

{
  "type": "supabase",
  "parameters": {
    "resource": "row",
    "operation": "delete",
    "tableId": "logs",
    "filterType": "string",
    "filterString": "created_at=lt.2024-01-01&level=eq.debug"
  }
}

Get a single row by an exact column match:

{
  "type": "supabase",
  "parameters": {
    "resource": "row",
    "operation": "get",
    "tableId": "users",
    "getFilters": {
      "conditions": [
        { "keyName": "email", "keyValue": "user@example.com" }
      ]
    }
  }
}

Read up to 50 orders that are either pending or high priority:

{
  "type": "supabase",
  "parameters": {
    "resource": "row",
    "operation": "getAll",
    "tableId": "orders",
    "returnAll": false,
    "limit": 50,
    "getAllFilterType": "manual",
    "getAllMatchType": "anyFilter",
    "getAllFilters": {
      "conditions": [
        { "keyName": "status", "condition": "eq", "keyValue": "pending" },
        { "keyName": "priority", "condition": "eq", "keyValue": "high" }
      ]
    }
  }
}

Read every row from a table in a non-public schema:

{
  "type": "supabase",
  "parameters": {
    "useCustomSchema": true,
    "schema": "analytics",
    "resource": "row",
    "operation": "getAll",
    "tableId": "events",
    "returnAll": true,
    "getAllFilterType": "none"
  }
}

Create a row from every property on the incoming item:

{
  "type": "supabase",
  "parameters": {
    "resource": "row",
    "operation": "create",
    "tableId": "customers",
    "dataToSend": "autoMapInputData"
  }
}

Read an entire table with no filtering:

{
  "type": "supabase",
  "parameters": {
    "resource": "row",
    "operation": "getAll",
    "tableId": "customers",
    "returnAll": true,
    "getAllFilterType": "none"
  }
}

Update exactly one customer by primary key:

{
  "type": "supabase",
  "parameters": {
    "resource": "row",
    "operation": "update",
    "tableId": "customers",
    "dataToSend": "autoMapInputData",
    "filterType": "manual",
    "matchType": "allFilters",
    "filters": {
      "conditions": [
        { "keyName": "id", "condition": "eq", "keyValue": "customer-123" }
      ]
    }
  }
}

Read products matching either of two conditions (OR logic):

{
  "type": "supabase",
  "parameters": {
    "resource": "row",
    "operation": "getAll",
    "tableId": "products",
    "returnAll": false,
    "limit": 100,
    "getAllFilterType": "manual",
    "getAllMatchType": "anyFilter",
    "getAllFilters": {
      "conditions": [
        { "keyName": "category", "condition": "eq", "keyValue": "electronics" },
        { "keyName": "featured", "condition": "eq", "keyValue": "true" }
      ]
    }
  }
}

Use a raw PostgREST string for a range query the manual builder cannot express:

{
  "type": "supabase",
  "parameters": {
    "resource": "row",
    "operation": "getAll",
    "tableId": "sales",
    "returnAll": true,
    "getAllFilterType": "string",
    "getAllFilterString": "amount=gte.1000&date=gte.2024-01-01&date=lt.2024-12-31"
  }
}

Create a row with a fixed set of columns, ignoring whatever else the item carries:

{
  "type": "supabase",
  "parameters": {
    "resource": "row",
    "operation": "create",
    "tableId": "users",
    "dataToSend": "defineBelow",
    "fieldsUi": {
      "fieldValues": [
        { "fieldId": "email", "fieldValue": "new@example.com" },
        { "fieldId": "role", "fieldValue": "user" },
        { "fieldId": "active", "fieldValue": "true" }
      ]
    }
  }
}

Update a profile while keeping timestamp and key columns out of the payload:

{
  "type": "supabase",
  "parameters": {
    "resource": "row",
    "operation": "update",
    "tableId": "profiles",
    "dataToSend": "autoMapInputData",
    "inputsToIgnore": "created_at,updated_at,id",
    "filterType": "manual",
    "matchType": "allFilters",
    "filters": {
      "conditions": [
        { "keyName": "user_id", "condition": "eq", "keyValue": "user-456" }
      ]
    }
  }
}

Tips

Use Supabase to create, read, update, or delete rows in Supabase (PostgreSQL) tables via the PostgREST API with filtering, pagination, and custom schema support.
