Postal Data API integration

Quick start

Call Postal Data API from your generated app's worker code via the OverSkill composio client. The toolkit slug below maps to Postal Data API's public Composio identifier — your app references it by name and OverSkill handles the OAuth round-trip.

// In your generated app's worker handler:
const composio = composioClient(env);

const result = await composio.execute(
  "POSTAL_DATA_API_ACTION_NAME",
  { /* action parameters — see Actions section below */ }
);

return new Response(JSON.stringify(result), {
  headers: { "Content-Type": "application/json" }
});

Replace ACTION_NAME with one of the slugs listed in the Actions section below. The composio client handles auth + rate limits automatically — no API key is exposed to user code.

Setup

Postal Data API is newly synced from Composio — our background bootstrap job hasn't created the auth config row yet. This usually takes a few minutes; if it's still pending after an hour, please reach out.
