# Reckon One

> Resources, examples, configuration and evidence for Reckon One.

Use the `@bijection/connectors/reckon-one` entrypoint to declare Reckon One resources.

## Availability

This page describes the pinned source package. Published availability is unestablished for this artifact. [Source build and package availability](https://docs.bijection.com/client/sdk-distribution.md).

## Resources and modes

| Resource | Mode | Description |
| - | - | - |
| Book list | `observed` | Keyset walk by (lastModifiedDateTime, id) in ticks, read-only |

Declare a resource in application code, then bind deployment-specific settings and credentials. See [typed resources](https://docs.bijection.com/integrations/resources.md), [connections](https://docs.bijection.com/integrations/connections.md) and [source inspection](https://docs.bijection.com/integrations/cli.md).

## Book list

### observed: Keyset walk by (lastModifiedDateTime, id) in ticks, read-only

The following example matches configuration `invoices`.

```ts theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
import { reckonOne } from "@bijection/connectors/reckon-one";

export const invoices = reckonOne.resource.observed({
  resource: "invoices",
  columns: { invoiceNumber: "string", totalAmount: "number" },
});
```

> **Inferred record types**
>
> ```ts theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
> Resource without an operational record table
> ```

#### Configuration: invoices

Case: `reckon-one/resource/observed/invoices`.

Connection and resource configuration are declared by this exact case.

Credential kind: `reckon_one`. Keep credential material in the private credential inventory.

## Provider guidance

`reckonOne.resource.observed({ resource, columns, pageSize?, lag?, every? })`
reads one list of a Reckon One book through the Reckon One API v2:
`GET <baseUrl>{bookId}/{resource}`, answered `{ "list": [...] }`. The binding's
setup names the `baseUrl` and the `bookId` (`GET books` lists the books a user
may read).

Every book entity Reckon's OpenAPI document lists with `lastModifiedDateTime`
(invoices, bills, credit notes, contacts, customers, suppliers, items, journals,
payments, receipts, purchase and sales orders, projects and others) can be
walked. Each request asks page one, `perPage` `pageSize` (100), for rows
strictly after the last (`lastModifiedDateTime`, `id`) read, ordered
`lastModifiedDateTime,id`:
`lastModifiedDateTime gt "T" or (lastModifiedDateTime eq "T" and id gt "G")`.
Reckon writes the time in .NET ticks and drops trailing zeros
(`2022-01-20T01:26:19.6389806Z`); the walk keeps all seven digits and writes the
bound back as Reckon wrote it. `id` is a GUID compared by Reckon's own ordering,
the same ordering the request sorts by. A finished pass carries the last pair
and the next re-reads from `lag` seconds (300) before it, deduplicating by
`lastModifiedDateTime`, the version.

Limits: a row with a null `lastModifiedDateTime` is never listed by the filter.
Amounts are JSON numbers, so columns are `string`, `integer`, `number` or
`boolean`, never exact. No deletion listing or webhook is documented, so a
deleted row stays published; no command is declared. Unconfirmed: the quoted
date-time literal (Reckon's example quotes a date, `invoicedate le "2020-03-31"`)
and how `gt` orders GUIDs.

Host: Reckon's OpenAPI document names `https://api-v2.reckonone.com`, while its
help centre's examples use `https://api.reckon.com/r1/v2/` behind the API
gateway that checks the subscription key. Use the gateway address Reckon gives
with the subscription key.

Bind a `reckon_one` credential: an `oauth_refresh` envelope for
`https://identity.reckon.com/connect/token` (client id and secret as Basic,
scopes `read write offline_access`; access tokens last 180 minutes, refresh
tokens 45 days unused), with the subscription key as a private resource header
`ocp-apim-subscription-key` (Reckon also accepts it as the `subscription-key`
query parameter; a missing key is a `401`). No Reckon book has been reached.
