Find documents

  1. Create a mongoDb credential.
  2. Search for MongoDB, connect it after the previous node, and select that credential.
  3. Leave Resource on Document and Operation on Find.
  4. Set Collection.
  5. Query (JSON Format) defaults to {} (match all). Change it to a filter JSON if needed. Select Execute step.

Under Document you also get Aggregate, Insert, Update, Delete, Find And Update, and Find And Replace.

Prefer Query Parameters ($1, $2) for dynamic values instead of embedding expressions in the query JSON.
