Changelog

Release notes for Microsoft Teams Notifications for WHMCS.

1.3.0 — 14 November 2026

A modernization release. The folder, class and display name are unchanged, and rules created by 1.2.0 keep working without edits.

Added

• Three per-rule message formats: Message + Card (both, default), Message only (message) and Card only (card).
• Per-rule Webhook Override, so a rule can post to a different Teams channel without changing the provider.
• Optional Card Header Name and Card Icon URL branding inside the card. The Teams sender remains Workflows.
• Per-rule Theme Colour validation: three- or six-digit hex, optional #, normalised to six uppercase digits.
• Per-rule Hide Attributes and Hide View Link toggles.
• Support for Power Automate Workflows trigger URLs alongside legacy Office 365 Incoming Webhook URLs, using the same MessageCard payload.
• Provider settings for Request Timeout, Strict Delivery and Allow Custom Host.
• Read-only Version row in the configuration dialog.
• Webhook validation before every request for both the provider URL and a per-rule override: HTTPS, no credentials, no fragment, host allowlist, path shape, port and signature rules.
• Actionable error mapping for HTTP 400, 401, 403, 404, 410, 413, 429 and 5xx, plus cURL DNS, connection, timeout and TLS failures.
• Detection of Teams errors returned inside an HTTP 2xx response.
• Log redaction for both legacy tokens and Workflows signatures.
• Payload size enforcement with fact trimming, message truncation and a clear failure when nothing can be removed.
• Markdown-aware truncation that closes an unterminated code fence.
• Mention neutralisation for @everyone, @here, @channel and @online.
• Full README and eight-page HTML documentation site.

Changed

• The default theme colour is now 0076D7 for both the test card and notifications.
• The connection test is always strict, so setup problems surface immediately.
• whmcs.json now declares type: whmcs-notifications and version 1.3.0.
• Attribute values are HTML-decoded and stripped of HTML before rendering.
• Empty attributes no longer produce dangling separators or blank facts.

Fixed

• Undefined-index warnings when the webhook, theme colour or attributes were missing.
• cURL failures were ignored; the module now checks the error number, HTTP status and response body.
• A valid empty or JSON response was incorrectly treated as a failure because it was not the string 1.
• Rules with no attributes produced an empty card section.
• Long notifications could exceed the Teams payload limit.
• Repeated HTML-escaping of & in Workflows URLs no longer causes HTTP 401 on provider save; the module decodes every escape layer.
• Message Format now saves and reloads correctly when another provider also defines a format dynamic field; the Teams field uses messageFormat.

Compatibility

• Folder, class, display name and themeColor rule key are unchanged.
• Rules without a webhook key use the provider webhook.
• Rules without a messageFormat use the legacy format key, then default to both.
• Blank cardName and cardIcon leave the existing card output unchanged.
• Legacy markdown and embed format values are mapped, not rejected.
• Rule appearance uses negative hideAttributes and hideLink checkboxes, because WHMCS does not submit an unchecked rule checkbox. Positive showAttributes and includeLink values are still honoured.
• No database tables, columns or migration scripts.

1.2.0 — legacy release

• MessageCard delivery to a Microsoft Teams Incoming Webhook.
• Per-rule theme colour and notification attributes rendered as facts.
• A single View in WHMCS action on every card.
• Connection test on provider save.
