Quickstart

Quickstart: call the Credicorp public API from Deno

Here is the idiomatic Deno way to make your first Credicorp public API call. List the live products from GET /public/v1/products, set a timeout, and turn the documented error envelope into an error you can handle — the pattern every other public-ring call reuses.

List products

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

Deno's fetch is Web-standard and needs no imports. Run with --allow-net=api.credicorp.co.uk so the permission is scoped to exactly the host you call.

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.

Next steps

From here, request a quote, submit an enquiry, and send applicants to apply. Handle errors with the shared error envelope.

Frequently asked questions

How do I scope network permissions?

Pass --allow-net=api.credicorp.co.uk (and the sandbox host) so Deno only permits the exact origins you use, following least privilege.

How do I handle errors in Deno?

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.
