STEP 1
Select PostgreSQL in workflow
Pick PostgreSQL app in the workflow builder [4] - just one click to select the app.
PostgreSQL Integration
Read and change rows in a PostgreSQL database, run your own query, and start a workflow when new rows appear. Works with PostgreSQL, Supabase, Neon, AWS RDS and other PostgreSQL servers. Use PostgreSQL inside visual workflows on WEXTL to compose logic that vendor integrations alone cannot cover. Pair it with app triggers and actions on the canvas to build end-to-end automations.

Supported triggers and actions for PostgreSQL integration
Triggers can detect changes in PostgreSQL and run actions that can create, search or modify data inside PostgreSQL automatically [3] — exactly how you set them.
- Watch rowsStart a workflow when new or changed rows appear in a table. Checks on your workflow schedule.
- Delete rowsDelete the rows that match your conditions.
- Execute a queryRun your own SQL, with values passed as parameters.
- Insert a rowAdd a row to a table and get it back.
- Insert or update a rowAdd a row, or update it when a row with the same key already exists.
- Select rowsRead rows from a table with simple conditions, a sort and a limit.
- Update rowsChange the rows that match your conditions.
How to integrate PostgreSQL in automation workflow?
3 simple steps to make your PostgreSQL connected with other apps in automation workflows on WEXTL. Up to 10 minutes integration set up.
STEP 2
Connect PostgreSQL
When prompted, authorize access to PostgreSQL in WEXTL once. PostgreSQL credentials are encrypted and never shared with WEXTL. Authorization will be reused in any future API calls [3].
PostgreSQL Access Approval
WEXTL wants to integrate with your PostgreSQL account. Approve?
STEP 3
Build a workflow
Build your workflow with PostgreSQL yourself or with WEXTL® AI Builder. Connect PostgreSQL to any available integrations [5], or use HTTP node to go beyond them.
PostgreSQL
Connect PostgreSQL to popular apps on WEXTL
Enter a name of the other app you want to sync with PostgreSQL below. Click on selected app to explore integration options with PostgreSQL. If the app you search for is not available in WEXTL yet, you can use HTTP node [10] instead to integrate it directly.
Example automation with PostgreSQL integration
Select Watch rows trigger from PostgreSQL - this will be a starting point in your automation. Whenever event happens in PostgreSQL, workflow will start [7] from Watch rows node.
Search for Delete rows, connect it as the next step of integration sequence. You can use filters between Watch rows and Delete rows, so only important data pass from Watch rows to the next step. WEXTL gives you full control over the process of PostgreSQL automation. All parts of workflow are visible on the canvas [4].
PostgreSQL on WEXTL has 7 modules for building built-in automations. Explore PostgreSQL documentation for more.

Frequently asked questions
Common questions about automating PostgreSQL in your workflows.
PostgreSQL is a built-in WEXTL workflow node. In practice, read and change rows in a PostgreSQL database, run your own query, and start a workflow when new rows appear. Works with PostgreSQL, Supabase, Neon, AWS RDS and other PostgreSQL servers. Configure the node's settings panel to control how it behaves inside your automation.
Drop PostgreSQL onto the visual canvas alongside app integrations and other built-in workflow nodes. Connect it to the steps before and after, configure its parameters, and it runs as part of the automation every time the workflow executes.
No. Most automations are built visually on the canvas by picking triggers, actions, and mapping fields. You can add custom JavaScript with Functions when advanced logic is needed — but our customers do that in rare cases [4].
Yes. WEXTL authenticates every connection per account, encrypts credentials at rest, and lets you enforce approvals and team-level access controls on any automation that uses PostgreSQL.
PostgreSQL runs alongside app integrations on the same workflow canvas. It receives data from upstream steps (triggers or other nodes) and passes results to downstream steps. Refer to our PostgreSQL Documentation for detailed inputs and outputs.
Absolutely. PostgreSQL works with every trigger source and every app integration on WEXTL. Combine it with native app triggers, scheduled polling, or the Custom Webhook node so PostgreSQL can react to events from any external system.
WEXTL is an AI-first visual canvas. The platform allows you to describe automation in plain text — and AI will wire nodes like PostgreSQL inside the workflow builder [4]. You can combine PostgreSQL with app integrations and other built-in workflow nodes (AI Agent, Human in the Loop, Condition, Aggregate Results) to build the exact flow you need.
