How do I insert a MongoDB document?
Short answer: You can insert one mongodb document in MongoDB Atlas by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the MongoDB Atlas Insert One MongoDB Document action to a workflow, map its 3 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.
Inputs
The fields this action accepts.
Every field can be mapped from an upstream trigger, AI step, table row, or hard-coded literal.
| Field | Type | Required | Description |
|---|---|---|---|
Database database | string | Required | – |
Collection collection | string | Required | – |
Document document | object | Required | JSON document to insert. Atlas auto-assigns `_id` if omitted. |
Sample request
{"database": "{{trigger.database}}","collection": "{{trigger.collection}}","document": "{{trigger.document}}"}
Returns
{"insertedId": "6a02b1f5c0e8b34d2a9c1234"}
Use these fields in downstream nodes for routing, logging, or error handling.

FAQ
Questions about Insert One MongoDB Document.
What does the Insert One MongoDB Document action do in MongoDB Atlas?
Inserts a single document into a collection. For bulk inserts, the bulk endpoint via HTTP action is much faster per-document.
What inputs does Insert One MongoDB Document require?
Required: Database, Collection, Document. Every input accepts a static value or a variable from any upstream node in your workflow.
Can I use dynamic inputs from earlier workflow nodes?
Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.
What happens if MongoDB Atlas returns an error?
The run history shows the failed step with its input and the error message MongoDB Atlas returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.
Does Insert One MongoDB Document support batch operations?
Run Insert One MongoDB Document inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within MongoDB Atlas's rate limits.
