ToolJet can connect to MongoDB to read and write data.

Manual Connection

To establish a manual connection with the MongoDB data source, click on the + Add new data source button located on the query panel or navigate to the Data Sources page from the ToolJet dashboard.

:::info Please make sure the Host/IP of the database is accessible from your VPC if you have self-hosted ToolJet. If you are using ToolJet cloud, please whitelist our IP. :::

ToolJet requires the following to connect to your MongoDB.

• Host
• Port
• Username
• Password

Note: It is recommended to create a new MongoDB user so that you can control the access levels of ToolJet.

Connect Using Connecting String

You can also use a Connection String by switching the method from the dropdown. You will be prompted to enter the details of your MongoDB connection.

ToolJet requires the following to connect to your MongoDB using Connecting String:

• Connection String

:::info The connection string typically looks like this: mongodb+srv://${username}:${password}@${cluster}/{database}.

For example: mongodb+srv://tooljettest:dummypassword@cluster0.urul7.mongodb.net/hrms :::

Note: Make sure to replace username, password, cluster, and database with your actual MongoDB details. If your MongoDB instance requires additional connection options, you can usually append these options to the connection string.

Querying MongoDB

1. Click on + Add button of the query manager at the bottom panel of the editor and select the database added in the previous step as the data source.
2. Select the operation that you want to perform and click Save to save the query.
3. Click on the Run button to run the query.

:::tip Query results can be transformed using transformations. Read our transformations documentation to see how: link :::
