List products
val client = OkHttpClient.Builder()
.callTimeout(10, TimeUnit.SECONDS)
.build()
val req = Request.Builder()
.url("https://api.credicorp.co.uk/public/v1/products")
.header("Accept", "application/json")
.build()
client.newCall(req).execute().use { res ->
if (!res.isSuccessful) error(res.code)
println(res.body?.string())
}On the JVM, OkHttp is the idiomatic choice; on Android it is already common. Reuse one OkHttpClient, set a call timeout, and parse with kotlinx.serialization or Moshi.
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
Can I use this on Android?
Yes. OkHttp is standard on Android. Do the call off the main thread (a coroutine on Dispatchers.IO) and never block the UI thread.
How do I handle errors in Kotlin?
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.
