List products
using var http = new HttpClient { Timeout = TimeSpan.FromSeconds(10) };
http.DefaultRequestHeaders.Accept.Add(new("application/json"));
var res = await http.GetAsync("https://api.credicorp.co.uk/public/v1/products");
res.EnsureSuccessStatusCode();
var json = await res.Content.ReadFromJsonAsync<ProductList>();Use a single shared HttpClient (never one per call) and ReadFromJsonAsync with a typed record. Register it via IHttpClientFactory in ASP.NET Core for pooling and resilience policies.
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
Should I new up HttpClient per request?
No — that exhausts sockets. Use one shared instance or IHttpClientFactory, which manages the lifetime and connection pool for you.
How do I handle errors in C# / .NET?
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.
