ToolJet can connect to MongoDB to read and write data.

<div style={{paddingTop:'24px'}}>

## 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](/docs/data-sources/overview) 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.

### Secure Sockets Layer (SSL)

- **SSL Certificate**: SSL certificate to use with MongoDB. Supported Types:
  - **None**: No SSL certificate verification.
  - **CA Certificate**: Requires a CA certificate to verify the server certificate.
  - **Client Certificate**: Requires a client certificate, client key, and CA certificate to authenticate with the server.

## 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.

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.

## Dynamic Queries

Dynamic queries in MongoDB can be used to create flexible and parameterized queries.

#### Example

// not supported: MongoDB classic syntax
{ createdAt: new Date('01/10/2020') }
```
