Embat Companies API

A `Company` represents a legal entity configured in your Embat workspace. Its `id` is the `companyId` used throughout this API: almost every other endpoint is scoped by `companyId` and requires it as a path parameter.`Company` is the parent entity of the API: it has no dependency on any other entity, while every other entity (Payments, Operations, Transactions, Contacts, Accounting Accounts, etc.) belongs to one. A company also has `Users` with access to it, retrievable with `GET /companies/{companyId}/users`.**Typical flow:**1. **Resolve the `companyId`.** Call `GET /companies` to list the companies your credentials have access to and pick the `id` of the one you want to work with.2. **Use it everywhere.** Pass that `id` as `companyId` in the path of any other endpoint in this API.3. **Optionally inspect the company.** `GET /companies/{companyId}` returns its legal name, administrative contact, tags and configuration (e.g. accounting currency).
