## Describe the question

Is it possible to append data in MongoDB using the node?

Say I have inserted the following entry in my database

{  
“\_id”: {  
“$oid”: “68e3b50812d86c5e8fc4ba8a”  
},  
“phone\_number”: “123456789”,  
“exchanges”: [  
{  
“user”: “Hi”,  
“assistant”: “Hi! What would you like to discuss today?”,  
“ts”: “06/10/25 14:24”  
}  
]  
}

Now I want to append this entry so that when the user sends another message and gets a reply back it will be saved as

{  
“\_id”: {  
“$oid”: “68e3b50812d86c5e8fc4ba8a”  
},  
“phone\_number”: “123456789”,  
“exchanges”: [  
{  
“user”: “Hi”,  
“assistant”: “Hi! What would you like to discuss today?”,  
“ts”: “06/10/25 14:24”  
},

{  
“user”: “2nd message”,  
“assistant”: “2nd reply”,  
“ts”: “2nd timestamp”  
}  
]  
}

Would this be possible to do with the MongoDB node or do I need something else?

## Please share your workflow

## Share the output returned by the last node

I’ve been trying to get it to work for over 2 weeks now with the help of chatpt so I have way too many error codes etc that I have accumulated over the past 2 weeks lol

Hello @Ozz123, you can use `Update Documents` operation in the MongoDB node.  
Something like that
