Connect CleverReach to Hypamoon

Yes, with one catch. CleverReach 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 CleverReach, answered from its own docs.

Public API docs
Yes. Public developer platform with the Core API v3, Flows API, webhooks and guides. Read the docs
A key you create yourself
Yes. You create an OAuth app yourself under Account, Extras, REST API, pick its scopes and register the callback URL. developers.cleverreach.com
Versions or a changelog
Yes. Versioned API (v3) with a dated changelog. developers.cleverreach.com
How it signs in
OAuth 2.0 with an app you create in your CleverReach account; access tokens expire and are renewed with a refresh token.
Webhooks
Yes. It can tell your app when something changes. developers.cleverreach.com
Hosting
Cloud
Condition
Sending mailings, agency subaccounts and automations need extra scopes that CleverReach support switches on.

Your own sign-up and preference pages on CleverReach, linked to your lists.

  • Groups, receivers, forms and mailings from CleverReach.
  • AI that sorts new sign-ups into the right group from what they tell you.
  • A page for your customers and a monthly email for you.

Ask your chat

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

  • How many receivers joined each group this month?
  • Which mailing had the most clicks this quarter?

When something happens

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

  1. When

    A receiver signs up or changes in CleverReach.

    AI decides

    AI reads the sign-up details and picks the group that fits.

    Then

    The receiver is added to that group in CleverReach.

    Ask for an approval step, and you check it first

A screen for your team or customers

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

  • For your customers

    Customers sign in and choose which newsletters they want to get.

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

Good to know

  • CleverReach signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for CleverReach takes more work: ask your chat to check this first.
  • Ask support for the extra scopes if you want to send mailings through the API.
