MongoDB Node

The MongoDB Node allows you to interact with MongoDB collections directly inside a DotPortion workflow. You can perform database operations such as inserting, querying, updating, and deleting documents without writing backend code.

​
Before You Start (Important)

Before using the MongoDB Node, you must configure your MongoDB connection.

​
Step 1: Add MongoDB Connection URL

  1. Go to Secrets in the DotPortion dashboard
  2. Add your MongoDB connection URL
  3. Save the secret

​
Step 2: Allow Network Access

In your MongoDB provider (e.g. MongoDB Atlas):
  • Enable Network Access
  • Allow connections from all IP addresses (0.0.0.0/0)
⚠️ This is required so DotPortion servers can access your database.

​
What the MongoDB Node Does

The MongoDB Node is responsible for:
  • Connecting to a configured MongoDB database
  • Performing CRUD operations on collections
  • Mapping workflow data to database fields
  • Returning database results to the workflow
It works similarly to MongoDB drivers used in traditional backend applications.

​
Configuration Fields

​
Select Collection

Choose the MongoDB collection you want to operate on. You can manage collections using Manage Collections.

​
Operation

Select the database operation to perform. Supported operations include:
  • Insert One
  • Find One
  • Find Many
  • Update One
  • Delete One

​
Available Fields

This section shows the schema fields available in the selected collection, including:
  • Field name
  • Data type
  • Required fields
This helps ensure correct data mapping.

​
Query Fields

Query Fields define how documents are matched. Used for:
  • Finding documents
  • Updating specific records
  • Deleting records
Example: 
_id = ObjectId value

​
Data Fields

Data Fields define what data is written or updated in the document. You can insert dynamic values using {{ }}. Example: 
{{requestparameters.title}}

​
Example: Insert a Todo

​
Configuration

Collection: Todo
Operation: Insert One Data Fields
  • title → {{requestparameters.title}}
  • description → {{requestparameters.description}}
  • isCompleted → {{requestparameters.isCompleted}}

​
Output

The MongoDB Node outputs the result of the operation. Example output: 
{
  "insertedId": "64fa2c9d8e..."
}
This output is available to downstream nodes.

​
Execution Rules

  • MongoDB connection must be configured in Secrets
  • Required fields must be provided
  • Query fields must match document schema
  • Errors stop workflow execution
