Quickstart: call the Credicorp public API from

Q: Are the Node examples compatible with Bun?

Yes. Bun implements the Web fetch and most of Node's API, so the public-ring examples run as-is.

Q: How do I handle errors in Bun?

Check the status code and read the error object from the body — error.code is the stable machine string to branch on. The pattern is identical across every endpoint.

List products

const res = await fetch(
  'https://api.credicorp.co.uk/public/v1/products',
  { headers: { Accept: 'application/json' } },
);
if (!res.ok) throw new Error(`${res.status}`);
const { data } = await res.json();
console.log(data);

Bun implements the standard fetch, so the Node examples run unchanged and start faster. Read the base URL from Bun.env or process.env.

Use the sandbox in development

Point the base host at https://sandbox.credicorp.co.uk/public/v1 in development and CI, and at https://api.credicorp.co.uk/public/v1 in production, driven by one environment variable. See choosing a base URL.
