Custom data

Attach arbitrary metadata to contacts for use in templates and segments.

Custom data is a flat key-value object stored on each contact. Use it to personalize templates or build segments for campaigns.

typescript

await plunk.contacts.update({
  email: "user@example.com",
  data: {
    firstName: "Ada",
    company: "Acme Inc",
    mrr: 49,
  },
});

Reference custom data fields inside a template with double curly braces, e.g. {{firstName}}.
