To configure this credential, you'll need:

Select Connection String as the Configuration Type.
A Connection String: To get your connection string in MongoDB, go to Database > Connect.
- Select Drivers.
- Copy the code you see in Add your connection string into your application code. It will be something like: mongodb+srv://yourName:yourPassword@clusterName.mongodb.net/?retryWrites=true&w=majority.
- Replace the <password> and <username> in the connection string with the database user's credentials you'll be using.
- Enter that connection string into n8n.
- Refer to Connection String for information on finding and formatting your connection string.
A Database name: this should be the name of the database that the user whose details you added to the connection string is logging into.
Select whether to Use TLS: Turn on to use TLS. You must have your MongoDB database configured to use TLS and have an x.509 certificate generated. Refer to MongoDB's x.509 documentation for more information. Add information for these certificate fields in n8n:
