Call the API from Express
const express = require('express');
const app = express();
const BASE = process.env.CREDICORP_BASE;
app.get('/api/products', async (req, res) => {
try {
const upstream = await fetch(`${BASE}/products`);
const body = await upstream.json();
res.set('Cache-Control', 'public, max-age=3600').json(body);
} catch (e) {
res.status(502).json({ error: 'upstream_unavailable' });
}
});Proxy the public read through your own Express route when you want to add caching, shape the payload, or keep a single origin for your front-end. This is also the pattern you extend later to add authenticated partner calls, keeping secrets on the server.
Point at sandbox in development
Set the base URL to https://sandbox.credicorp.co.uk/public/v1 in development and CI, and to https://api.credicorp.co.uk/public/v1 in production — driven by the one environment variable your framework already exposes. See choosing a base URL.
Next steps
From here you can add a quote form, an enquiry submission or an embeddable product picker. Send applicants to apply to start a real journey.
Frequently asked questions
Why proxy a public read?
To add your own caching, trim the payload for your UI, or unify your front-end's origin. It is also the seam where you later add authenticated partner calls safely.
Should I cache the product list?
Yes. The catalogue changes infrequently, so cache it for the response's max-age. This keeps the API off your hot path and well under the rate limit.
