convert user capture

Hi everyone, I have a simple for some but not for me 🙂 issue. When the user answers yes or no to a capture, I need to convert it to true or false when I send my api call to create the record. I would like to do this so it's reusable for several captures in the flow. I tried functions but did not work as expected. Any other suggestions? Thanks in advance.

You’ve got two easy, reusable ways to flip a “yes / no” capture into a true / false value before you hit your API step. ──────────────────────── 1) Inline conversion right inside the API body
──────────────────────── The JSON Body editor lets you use little JS expressions inside {{= … }}.
Example (assume the capture is stored in {yes_no}):

{
  "agreed": {{= yes_no.toLowerCase() === 'yes' }}
}

{
  "agreed": {{= yes_no.toLowerCase() === 'yes' }}
}

When the request is sent: • if the user said “yes” → "agreed": true
• anything else (no, nope, etc.) → "agreed": false Nothing else to maintain, and you can reuse that one-liner anywhere you reference the variable. ──────────────────────── 2) A reusable Function block (if you prefer a dedicated step)
──────────────────────── Create a Function step with one INPUT variable (e.g. answer) and one OUTPUT variable (e.g. bool_answer).
Paste this code:

export default async function main(args) {
  const a = (args.inputVars.answer || '').trim().toLowerCase();
  return {
    outputVars: {
      bool_answer: a === 'yes' || a === 'y' || a === 'true' || a === '1'
    }
  };
}

export default async function main(args) {
  const a = (args.inputVars.answer || '').trim().toLowerCase();
  return {
    outputVars: {
      bool_answer: a === 'yes' || a === 'y' || a === 'true' || a === '1'
    }
  };
}

• Drop this Function anywhere you need the conversion.
• Pass the capture into answer, the step spits out bool_answer (true/false) ready for your API body. Either route keeps your flow clean and 100 % reusable. Pick the one that fits your style!

this is great. Do you know if calling this function multiple times (5x +) will increase the number of credits consumed? The credits VF use it's crazy. a conversation in my flow ranges from 40 to 60. I would need hundreds of thousands to roll it out to production. I appreciate the help.
