Overview
This node, part of a multifunctional toolbox, provides utilities to generate random numbers within a specified range. It supports generating either integer or decimal numbers between user-defined start and end values. This functionality is useful in scenarios such as creating randomized test data, generating unique identifiers, or simulating numeric inputs for workflows.
For example, you could use this node to:
- Generate a random integer between 1 and 100 for sampling purposes.
- Create a random decimal number between 0.5 and 5.5 for financial simulations.
Properties
| Name | Meaning |
|---|---|
| Code Variables | A collection of named variables defined in the code editor that can be assigned specific values. Useful for passing dynamic values into custom code functions. |
| Range Start | The minimum value (inclusive) of the generated number range. |
| Range End | The maximum value (inclusive) of the generated number range. |
| Type | Specifies whether the generated number should be an "Integer" or a "Decimal". |
Output
The output JSON contains the generated number(s) based on the input parameters. Each execution returns one or more numbers within the specified range and type.
If multiple input items are processed, the output will be an array of generated numbers corresponding to each input item.
No binary data output is produced by this operation.
Dependencies
- Requires an API key credential for authentication with the external service powering the node's operations.
- The node makes HTTP POST requests to an external API endpoint under the path
generate/numberwith parameters specifying the type and range.
Troubleshooting
Common issues:
- Providing a
Range Startvalue greater thanRange Endmay cause unexpected results or errors. - Omitting required properties like
Range Start,Range End, orTypewill prevent successful execution. - Incorrect API credentials or network issues can lead to failed requests.
- Providing a
Error messages:
- Errors related to invalid parameter values typically indicate misconfiguration of input properties.
- Authentication errors suggest missing or invalid API key credentials; ensure proper setup in n8n.
- Network or timeout errors require checking connectivity to the external API service.
