One version, by its number — the address a caller uses when it must see the terms a Loan was issued under, not whatever is newest. Every version stays readable: a new version supersedes nothing that was.

Path parameters

string

required

The Tenancy asking.

string

required

The configuration.

integer

required

The version, counting from 1. One that never existed is 404.

Response

The stored configuration at that version, with the values that version was written with — a later version does not reach it. created_at is the configuration’s creation and is the same on every version — a new version does not move it. Beside values, effective answers every field the frame declares with the value a Loan under this version takes, and whether it was stated or is the Platform’s default — as creation answers it. values is never filled in.
