The check

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

Public API docs
Yes. Public OpenAPI reference for API v1 and v2, readable without an account. Read the docs
A key you create yourself
Yes. Each user finds an API token under My settings and can generate a new one at any time; the token carries that user's permissions. weclapp.com
Versions or a changelog
Yes. Versioned API (v1 and v2) with a changelog; an old version stays available for at least one year after a new one. weclapp.com
How it signs in
A per-user API token in the AuthenticationToken header, or HTTP Basic with * as the username and the token as the password.
Webhooks
Yes. It can tell your app when something changes. weclapp.com
Hosting
Cloud

In practice

What it takes in a real weclapp administration.

Getting access
Each weclapp user creates or renews an API token under My settings; give the integration its own user with only the rights it needs.
Limits
No fixed rate limit. Parallel requests per tenant are queued, and after about 30 seconds in the queue the API answers 429; weclapp asks for retries with backoff and a request timeout of at least one minute. weclapp.com
Writing
Read and write. Create (POST) and update (PUT) records such as customers, articles and sales orders, within the rights of the token's user.
Cost
Not published.

Your own customer portal on weclapp, built around how your customers order.

  • Customers, articles, sales orders and invoices, through the weclapp API.
  • AI that checks new orders and flags customers who start paying late, with you approving every change.
  • A portal for your customers and a short weekly email for you.

Ask your chat

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

  • Which customers have invoices more than 30 days overdue?
  • Which articles are below their minimum stock?

When something happens

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

  1. When

    A new sales order is created in weclapp.

    AI decides

    AI checks the prices, the delivery date and the customer's payment history.

    Then

    Sales gets an email when an order needs a second look.

A screen for your team or customers

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

  • For your customers

    Customers sign in and see their orders, delivery status and open invoices from weclapp.

Add Hypamoon

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

  • Agent on a schedule

    Once a week, an agent emails you the customers who order less than they used to.

weclapp 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 weclapp waits for your approval, one call at a time. How adapters work

Good to know

  • Your adapter uses a fixed key: you paste it once in the Hypamoon portal, never in the chat, and it only goes to the API host you allow.
  • The address has your tenant in it, for example yourcompany.weclapp.com/webapp/api/v2. The token has the same rights as the user it belongs to.
