The Coinbase Payment Gateway Module enables WHMCS to accept Bitcoin and cryptocurrency payments via Coinbase. Version 3.0.6 released on 11.27.2018 is the latest, adding FontAwesome 5 icon support with v4 fallback for WHMCS 7.6+. This changelog preserves the exact details of every release while adding context on why each change matters for payment reliability, API compatibility, and system stability.

Updates address evolving Coinbase APIs, WHMCS UI and core changes, callback and webhook handling, library dependencies, and edge cases such as mispayments or sub-directory installations. Running an outdated version risks broken callbacks, missing transaction types, icon rendering failures, or incompatibility after Coinbase platform updates.

#Major Milestones

Version 3.0.3 rewrote the module for the new Coinbase Commerce system, removed the unsupported Coinbase Balance Widget, and eliminated the bundled newer Guzzle dependency. This ensured continued functionality after Coinbase deprecated prior merchant tools. Version 2.0.0 previously rewrote for Coinbase API v2, removed subscriptions support, strengthened callback signature verification by dropping the Callback Secret, and improved wallet balance display.

The 2.x series resolved licensing, autoloader, and WHMCS 7 visual issues. Earlier 1.x releases introduced refunds, subscription handling, WHMCS 5/6 compatibility, ISO 4217 XBT currency code, and Public Pay integration. These incremental fixes prevented rounding errors, SQL creation failures on certain MySQL setups, image loading problems in sub-directories, and jQuery CDN dependency issues.

#Technical Context and Pitfalls Addressed

Callback improvements appear throughout the history because accurate webhook processing directly determines whether invoices are marked paid, transactions logged, or mispayments flagged. Removing reliance on external jQuery CDNs and Google's links in version 2.0.4 eliminates outages when third-party hosts are unreachable or blocked. The Guzzle autoloader fix in 2.0.7 prevented WHMCS 7.2.x from loading incorrect library versions that would cause fatal errors.

  • Local jQuery loading and updated timers improve invoice page performance and remove external dependencies.
  • FontAwesome 5 support with v4 fallback maintains UI consistency without breaking older WHMCS themes.
  • Vendor directory organization for libraries follows current PHP standards and reduces include collisions.

#Webhook Testing

Support for charge:confirmed webhook testing added in 3.0.4 allows verification that payment confirmation events update WHMCS invoices immediately. Incorrect handling here leads to delayed order fulfillment or duplicate charges.

json 
{
  "event": {
    "type": "charge:confirmed",
    "data": {
      "code": "ABC123",
      "pricing": {
        "local": {
          "amount": "10.00",
          "currency": "USD"
        }
      }
    }
  }
}

Use Coinbase's test tools against your configured endpoint to confirm signature validation and transaction lookup behavior before production use.

#Practical Takeaway

Match your installed module version against this changelog to confirm you have fixes for known callback, licensing, and UI problems. Upgrade promptly after Coinbase or WHMCS releases to avoid deprecated API paths or broken icons. Test webhook delivery and Public Pay flows after any update.
