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.
