Rebranding Announcement
Paynote is Becoming Seamless ACH
A name that better reflects what our platform does — and aligns it with the broader SeamlessChex family. Your account, your data, and your integrations stay exactly the same.
Please note: starting June 23, 2026, all resources — including documentation, plugins, API references, and portal links — will be updated and reflect the latest information.
Overview
Paynote is rebranding to Seamless ACH — a name that better reflects what our platform does and aligns it with the broader SeamlessChex product family.
This is a branding change only. The core platform, your account, your data, your API keys, and your existing integrations are not affected.
One action is required from merchants who use API integrations: the new API URL is https://api.seamlesschex.com/ach/v2, available starting June 23, 2026. The current URL will continue to work until August 23, 2026 — update your integrations before the deadline.

⚠️ Action Required — New API URL
The most important change that requires action from you is the introduction of a new API URL.
If you use any of the following, you will need to update the API URL:
- Custom integrations — any code that makes direct calls to the Paynote API
- WordPress plugin — an updated version will be released automatically; updating the plugin will apply the new URL
- CheckoutJS — update your integration per the documentation. Learn more →
- CRM integrations (HubSpot, Salesforce, Zapier, etc.) — update the endpoint URL in your integration settings
- Any other direct API usage
The new API URL https://api.seamlesschex.com/ach/v2 is available starting June 23, 2026. The current URL https://api-paynote.seamlesschex.com/v2 will continue to work until August 23, 2026. Update your integrations before that date.
New Multi Login
As part of this transition, we are launching a new unified login page at dashboard.seamlesschex.com.
- If you use only Paynote / Seamless ACH — you will sign in and land on your dashboard at dashboard.seamlesschex.com/ach/
- If you also use SeamlessChex eCheck — you will see a product selector; eCheck opens at dashboard.seamlesschex.com/echeck/
- Your email, password, and credentials remain the same
