Overview

This custom node provides multiple text and data manipulation operations under a single "Custom" resource. Specifically, the Generate OTP Code operation creates a one-time password (OTP) string based on user-defined parameters such as type and length. This is useful in scenarios requiring secure verification codes for authentication, password resets, or transaction confirmations.

Practical examples include:

  • Generating numeric OTPs for SMS verification.
  • Creating alphanumeric OTPs for email-based two-factor authentication.
  • Producing text-only OTPs for systems that require non-numeric codes.

Properties

Name Meaning
CJ Token Your API token from sifuim.com used to authenticate requests.
OTP Type Type of OTP to generate. Options: Number Only, Text Only, Combine (Number + Text).
Character Length Number of characters for the OTP code (e.g., 6 means the OTP will be 6 characters long).

Output

The output JSON object contains:

  • otpType: The selected OTP type ("number", "text", or "combine").
  • characterLength: The length of the generated OTP.
  • generatedOtp: The actual generated OTP string matching the specified type and length.

Example output JSON:

{
  "otpType": "number",
  "characterLength": 6,
  "generatedOtp": "492837"
}

No binary data output is produced by this operation.

Dependencies

  • Requires a valid API token credential ("CJ Token") from sifuim.com for authentication.
  • The node internally calls a helper function to generate the OTP and deduct credit via the API.
  • No additional external services are explicitly required beyond the API token and network access to sifuim.com.

Troubleshooting

  • Invalid or missing API token: The node validates the provided token before execution. Ensure the CJ Token is correct and active.
  • Unsupported OTP type or invalid character length: The node expects predefined OTP types and a positive integer length. Providing unsupported values may cause errors.
  • API credit deduction failure: If the API call to deduct credit fails, the node attempts to continue but may log an error. Verify your account has sufficient credits.
  • Unhandled operation or resource: Errors occur if the resource or operation name is incorrect or not implemented.
