OpenCart 4.x
The Speend payment extension for OpenCart 4 supports redirect and on-site (host-to-host) modes: the customer picks a token and network and sees the address, QR code and countdown without leaving your store. Order statuses are synced by signed webhooks, and refunds are sent back in crypto to the customer address. No chargebacks, no custody.
Downloads the latest release as a ZIP archive. · v1.0.2
Requirements
Installation & setup
Download the archive from this page. Do not rename «speend.ocmod.zip» — OpenCart derives the extension code from the file name.
In the admin open Extensions → Installer, click Upload and upload the archive — wait for the install to finish.
Open Extensions → Extensions, choose the «Payments» type, find Speend and click «+» (Install), then «Edit».
Paste your Merchant UUID and API key (and the Webhook password if you set one), enable the method and save — the plugin verifies the credentials automatically.
Choose the payment mode (Redirect or On-site), the style and the order statuses. The webhook URL is configured automatically.
Upgrading: uninstall the previous version in Extensions → Installer first, then install the new archive — OpenCart will not install an extension with the same code on top.
