Icons describe general node roles, inferred from node types. Inspect the parameters for the configured action.
Drag to pan; use + and − to zoom. Reconstructed from the exported node positions; nothing runs here. Dashed lines represent non-main connections. Full node names and notes appear below.
How it works
The exported workflow contains the following configured nodes. Their connections are shown above; inspect the JSON for the complete logic, expressions, and external actions.
| Node | Category | Type | Operation |
|---|---|---|---|
| On new manual Chat Message | Trigger | Manual Chat Trigger | See node parameters |
| OpenAI Assistant | AI & models | Open Ai Assistant | See node parameters |
| Execute Workflow Trigger | Trigger | Execute Workflow Trigger | See node parameters |
| Mapping data | Code | Code | See node parameters |
| List countries? | Routing | If | See node parameters |
| Mapping data1 | Code | Code | See node parameters |
| Return country list | Transform | Edit Fields | See node parameters |
| Return specific capital | Transform | Edit Fields | See node parameters |
| Tool to call the workflow below | Subworkflow | Tool Workflow | See node parameters |
| Concatenate country names | Transform | Summarize | See node parameters |
| Get the matching country's details | Transform | Merge | See node parameters |
| Tool: Get current date and time | Code | Tool Code | See node parameters |
Setup
- Download the JSON and import it into an isolated n8n instance. Leave the workflow inactive.
- Connect your own credentials through n8n’s credential store. Replace
REPLACE_WITH_*values with your resource identifiers. - Inspect API destinations, Code nodes, database queries, file paths, and outbound actions.
- Run with synthetic data and harmless destinations. Enable triggers only after checking the actual outputs.
Requirements
An n8n instance with the listed node types and compatible versions. Service-connected workflows may require accounts, credentials, or paid APIs.
Credential types declared in the source
