whatsapp-extract-processor

whatsapp-extract-processor is a Vue web app that ingests a WhatsApp chat export and enriches each participant. For every contact it calls the WhatsApp Data API to attach the display name, business status and profile picture, turning a flat chat log into a contact directory.

It is one of the few UI-based integrations in the ecosystem, and it explicitly credits CheckLeaked as the enrichment source in its interface. A good example of per-contact fan-out: one API call per unique account id parsed from the export.

The same call

// One enrichment call per unique contact
async function enrich(accountId) {
  const res = await fetch(
    `https://wp-data.p.rapidapi.com/number/${accountId}`,
    { headers: {
        "x-rapidapi-host": "wp-data.p.rapidapi.com",
        "x-rapidapi-key": globalThis._importMeta_.env.VITE_RAPIDAPI_KEY,
    } },
  );
  return res.json();
