Can MongoDB connect with Postgres?

Yes, MongoDB can connect with Postgres using n8n.io. With n8n, you can create workflows that automate tasks and transfer data between MongoDB and Postgres. Configure nodes for MongoDB and Postgres in the n8n interface, specifying actions and triggers to set up their connection.

Can I use MongoDB’s API with n8n?

Yes, with n8n, you can programmatically interact with MongoDB’s API via pre-defined supported actions or raw HTTP requests. With the HTTP Request node, you create a REST API call. You need to understand basic API terminology and concepts.

Is n8n secure for integrating MongoDB and Postgres?

Yes, it is safe to use n8n to integrate MongoDB and Postgres. n8n offers various features to ensure the safe handling of your data. These include encrypted data transfers, secure credential storage, RBAC functionality, and compliance with industry-standard security practices (SOC2 compliant). For hosted plans, data is stored within the EU on servers located in Frankfurt, Germany. You can also host it on your own infrastructure for added control. Learn more about n8n’s security practices here.

How to get started with MongoDB and Postgres integration in n8n.io?

To start integrating MongoDB and Postgres in n8n, you have different options depending on how you intend to use it: n8n Cloud: hosted solution, no need to install anything. Self-host: recommended method for full-control or customized use cases. Unlike other platforms that charge per operation, step, or task, n8n charges only for full workflow executions. This approach guarantees predictable costs and scalability, no matter the complexity or volume of your workflows.

How to connect MongoDB and Postgres

Step 1: Create a new workflow
Step 2: Add and configure nodes
Step 3: Connect
Step 4: Customize and extend your integration
Step 5: Test and activate your workflow

Step 1: Create a new workflow and add the first step

In n8n, click the "Add workflow" button in the Workflows tab to create a new workflow. Add the starting point – a trigger on when your workflow should run: an app event, a schedule, a webhook call, another workflow, an AI chat, or a manual trigger. Sometimes, the HTTP Request node might already serve as your starting point.

Step 2: Add and configure MongoDB and Postgres nodes

You can find MongoDB and Postgres in the nodes panel. Drag them onto your workflow canvas, selecting their actions. Click each node, choose a credential, and authenticate to grant n8n access. Configure MongoDB and Postgres nodes one by one: input data on the left, parameters in the middle, and output data on the right.

Step 3: Connect MongoDB and Postgres

A connection establishes a link between MongoDB and Postgres (or vice versa) to route data through the workflow. Data flows from the output of one node to the input of another. You can have single or multiple connections for each node.

Step 4: Customize and extend your MongoDB and Postgres integration

Use n8n's core nodes such as If, Split Out, Merge, and others to transform and manipulate data. Write custom JavaScript or Python in the Code node and run it as a step in your workflow. Connect MongoDB and Postgres with any of n8n’s 1000+ integrations, and incorporate advanced AI logic into your workflows.

Step 5: Test and activate your MongoDB and Postgres workflow

Save and run the workflow to see if everything works as expected. Based on your configuration, data should flow from MongoDB to Postgres or vice versa. Easily debug your workflow: you can check past executions to isolate and fix the mistake. Once you've tested everything, make sure to save your workflow and activate it.

ETL pipeline for text processing

This workflow allows you to collect tweets, store them in MongoDB, analyse their sentiment, insert them into a Postgres database, and post positive tweets in a Slack channel.

Cron node: Schedule the workflow to run every day

Twitter node: Collect tweets

MongoDB node: Insert the collected tweets in MongoDB

Google Cloud Natural Language node: Analyse the sentiment of the collected tweets

Set node: Extract the sentiment score and magnitude

Postgres node: Insert the tweets and their sentiment score and magnitude in a Posgres database

IF node: Filter tweets with positive and negative sentiment scores

Slack node: Post tweets with a positive sentiment score in a Slack channel

NoOp node: Ignore tweets with a negative sentiment score
