List products
use reqwest::Client;
let client = Client::builder()
.timeout(std::time::Duration::from_secs(10))
.build()?;
let res = client
.get("https://api.credicorp.co.uk/public/v1/products")
.header("Accept", "application/json")
.send().await?
.error_for_status()?;
let body: serde_json::Value = res.json().await?;Use reqwest with tokio, build one Client and reuse it, and let error_for_status() turn a non-2xx into an error. Model the response with serde structs for full type safety.
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
reqwest or hyper?
reqwest for almost everything — it is ergonomic and handles TLS and pooling. Drop to hyper only if you need low-level control.
How do I handle errors in Rust?
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.
