Connect PlentyONE to Hypamoon

Yes, with one catch. PlentyONE has an open API that you can use yourself, but it signs in with OAuth only, and that takes more work in a Hypamoon adapter today.

Open

The check

Three questions about the API of PlentyONE, answered from its own docs.

Public API docs
Yes. Public developer portal with REST API guides and reference. Read the docs
A key you create yourself
Yes. You log in with a back end user of your own system through /rest/login and get an access token; the REST API needs the Expand contract or higher. developers.plentyone.com
Versions or a changelog
Yes. You can pin an API version with a versioned media type in the Accept header. developers.plentyone.com
How it signs in
POST a back end username and password to /rest/login and send the returned access token as a bearer token; the token expires after 24 hours and comes with a refresh token.
Webhooks
Yes. It can tell your app when something changes. developers.plentyone.com
Hosting
Cloud
Condition
REST API access needs the Expand contract or higher; Lite and Lite+ do not include it.

In practice

What it takes in a real PlentyONE administration.

Getting access
Create a back end user with the REST API rights the integration needs; the adapter logs in with that user at /rest/login.
Limits
On Expand and Scale: 200 read calls per user per minute and 166,000 per system per day; 80 write calls per user per minute and 48,000 per system per day. Some routes have their own limits. developers.plentyone.com
Writing
Read and write. Write calls are part of the REST API, within the rights of the back end user and the write limits.
Cost
Needs the Expand contract or higher. developers.plentyone.com

Your own B2B portal on PlentyONE, next to the shops and marketplaces you already run.

  • Orders, items, stock and contacts from PlentyONE.
  • AI that checks new orders and spots items about to run out.
  • A portal for your business customers and an email when something needs a look.

Ask your chat

Answers straight from your PlentyONE data, in Claude or another chat with the full Hypamoon connection.

  • Which orders from last week still have no shipping label?
  • Which items sell well but have less than two weeks of stock?

When something happens

PlentyONE sends a webhook to your app, and the app asks AI what happens next.

  1. When

    A subscribed event in PlentyONE, such as a new order.

    AI decides

    AI checks the order for an odd address, price or quantity.

    Then

    The team gets an email when an order needs a look.

A screen for your team or customers

An app on your own address, with sign-in, on top of the same PlentyONE data.

  • For your customers

    Business customers sign in, see their own prices and order history, and reorder.

Add Hypamoon

Text messages, email, phone, payments and agents run in the same project as the adapter.

  • Agent on a schedule

    Every Monday, an agent emails you the items to reorder.

PlentyONE stays the core: your chat builds the rest on its API, as an adapter plus an app and agents in your Hypamoon project. Reading starts after you click Allow in the portal. Every change an agent or a chat makes in PlentyONE waits for your approval, one call at a time. How adapters work

Good to know

  • PlentyONE signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for PlentyONE takes more work: ask your chat to check this first.
  • Tokens expire after 24 hours, so an adapter has to log in again or refresh. The number of concurrent sessions is limited, 3 by default.
