Connect MongoDB to PostgreSQL
Automate workflows between MongoDB and PostgreSQL. No coding required.
What you can automate between MongoDB and PostgreSQL
These are the most popular automations teams set up between MongoDB and PostgreSQL. Each one runs automatically once activated — no manual steps.
Insert record when new record created
Add a new row or document automatically when when a new row or document is added.

Add a new row or document automatically when when a new row or document is added.
Sync MongoDB changes to PostgreSQL
Keep PostgreSQL updated when when data is modified in the database.
What syncs between MongoDB and PostgreSQL
When an event occurs in MongoDB, the relevant data is automatically sent to PostgreSQL. Arahi maps the fields between both apps so the data arrives in the right format — no manual formatting or exports required.
Data from MongoDB
- Records / documents
- Collection items
- Field values
- Timestamps
- Unique IDs

How to connect MongoDB to PostgreSQL
Follow these steps to set up your integration. The entire process takes under 5 minutes.
What you'll need
- An active MongoDB account with read/write permissions
- An active PostgreSQL account with read/write permissions
- A free Arahi AI account (sign up takes 30 seconds)
Create your Arahi AI account
Sign up at app.arahi.ai — it's free and takes 30 seconds. No credit card required. You'll land on the dashboard where you can create your first workflow.
Authenticate MongoDB
Click "Add Connection" and select MongoDB from the app directory. You'll be redirected to MongoDB's authorization page. Grant Arahi read/write access to your database collections and records. You specify which databases and collections the integration can use.
Authenticate PostgreSQL
Same process for PostgreSQL. Click "Add Connection," select PostgreSQL, and authorize access. Grant Arahi read/write access to your database collections and records. You specify which databases and collections the integration can use.
Choose your trigger
Select what event starts the workflow. For this integration, popular triggers include: new record created in mongodb or new record created in postgresql. The trigger fires automatically whenever that event happens — no manual intervention.
Configure the action
Define what happens when the trigger fires. For example: insert record in postgresql. Map the data fields between MongoDB and PostgreSQL so the right information lands in the right place.
Test and activate
Run a test to confirm data flows correctly between MongoDB and PostgreSQL. Check that the fields map as expected, then toggle the workflow on. It runs 24/7 from here — Arahi handles retries, error logging, and monitoring automatically.
Why connect MongoDB and PostgreSQL?
Manually moving data between MongoDB and PostgreSQL is error-prone and eats into your team's productive hours. Connecting them through Arahi eliminates that overhead — events in one app trigger actions in the other automatically.

Frequently asked questions
Everything you need to know about connecting MongoDB and PostgreSQL.
How do I connect MongoDB to PostgreSQL?
Sign up for a free Arahi AI account, then click "Add Connection" to authenticate both MongoDB and PostgreSQL via OAuth. Choose a workflow template — like syncing databases events to databases actions — customize the field mapping, and activate. The entire setup takes under 5 minutes.
What can I automate between MongoDB and PostgreSQL?
You can automate a wide range of workflows: sync new MongoDB events to PostgreSQL actions, trigger PostgreSQL updates when MongoDB data changes, create PostgreSQL records from MongoDB events, and build conditional workflows with filters and field mapping. Each workflow runs 24/7 with automatic retries.
Is the MongoDB and PostgreSQL integration free?
Arahi AI includes 100 free actions per month on the Starter plan — enough for most small teams. If your MongoDB-to-PostgreSQL workflows need more volume, paid plans start at $29/month with unlimited workflows and priority execution.
Is my MongoDB data secure when connected to PostgreSQL?
Yes. Arahi uses OAuth 2.0 for authentication — we never store your MongoDB or PostgreSQL passwords. All data is encrypted in transit (TLS 1.3) and at rest (AES-256). Your databases data is only accessed when a workflow runs, and you can revoke access at any time from your Arahi dashboard.
Can I sync data both ways between MongoDB and PostgreSQL?
Yes. You can set up workflows that trigger from either MongoDB or PostgreSQL. For example, create a workflow where MongoDB events update PostgreSQL, and a separate one where PostgreSQL changes sync back to MongoDB. Each direction is configured independently so you have full control.
Do I need technical skills to connect MongoDB and PostgreSQL?
No coding is required. Arahi's visual workflow builder lets you configure triggers, actions, and field mapping with clicks. If you can use MongoDB and PostgreSQL, you can set up the integration. Most users are running their first workflow within 10 minutes.
