Baseline: main <strong>23.0+</strong>. Requires the Pull/queue server to be enabled (<code>CPullOptions::GetQueueServerStatus()</code>); otherwise events are dropped after buffering logic.</p>\n<pre><code>\\Bitrix\\Main\\Loader::includeModule('pull');\n</code></pre>\n<h2>Pull vs Messenger vs Agents</h2>\n<table>\n<thead>\n<tr>\n<th>Mechanism</th>\n<th>Use for</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td><strong>Pull</strong></td>\n<td>Instant UI sync (“row updated”, counters, presence-like hints)</td>\n</tr>\n<tr>\n<td><strong>Messenger</strong> (<code>bitrix-background-jobs</code>)</td>\n<td>Reliable async <strong>work</strong> with retries/queues (<strong>Since 25.100.300</strong>, alpha)</td>\n</tr>\n<tr>\n<td><strong>Agents / cron</strong></td>\n<td>Periodic batch jobs, cleanup, polling external systems</td>\n</tr>\n</tbody>\n</table>\n<p>Do not use Pull as a job queue. Do not use Messenger to push browser paint updates — emit Pull from the worker when the UI must refresh.</p>\n<h2>Send to User(s) from PHP</h2>\n<p>Primary API: <code>Bitrix\\Pull\\Event::add($recipient, array $parameters, $channelType = \\CPullChannel::TYPE_PRIVATE)</code>.</p>\n<p>Required in <code>$parameters</code>: <code>module_id</code>, and either <code>command</code> (+ optional <code>params</code>) or push payload fields.</p>\n<pre><code>&lt;?php declare(strict_types=1);\n\nuse Bitrix\\Main\\Loader;\nuse Bitrix\\Pull\\Event;\n\nLoader::includeModule('pull');\n\nEvent::add($userId, [\n    'module_id' =&gt; 'vendor.module',\n    'command' =&gt; 'item.updated',\n    'params' =&gt; [\n        'id' =&gt; $itemId,\n        'title' =&gt; $title,\n    ],\n    // 'expiry' =&gt; 86400, // optional; default applied in Event::prepareParameters\n]);\n\n// Multiple users:\nEvent::add([1, 2, 3], [\n    'module_id' =&gt; 'vendor.module',\n    'command' =&gt; 'list.refresh',\n    'params' =&gt; [],\n]);\n</code></pre>\n<ul>\n<li>Recipients: user IDs, channel IDs (32-char strings), or <code>Bitrix\\Pull\\Model\\Channel</code> instances.</li>\n<li>Channel types: <code>\\CPullChannel::TYPE_PRIVATE</code> (default), <code>TYPE_SHARED</code>, etc.</li>\n<li>Sending is deferred via <code>Application::addBackgroundJob</code> / <code>Event::send</code> on epilog — usually you only call <code>add()</code>.</li>\n<li>Legacy wrappers: <code>CPullStack</code>, <code>Bitrix\\Pull\\Push::add</code> (push notifications path).</li>\n</ul>\n<p>On failure, inspect <code>Event::getLastError()</code>.</p>\n<h2>Shared Tags (<code>CPullWatch</code>)</h2>\n<p>Subscribe users to a <strong>tag</strong>, then broadcast to everyone watching that tag:</p>\n<pre><code>&lt;?php declare(strict_types=1);\n\nuse Bitrix\\Main\\Loader;\n\nLoader::includeModule('pull');\n\n\\CPullWatch::Add($userId, 'VENDOR_ITEM_' . $itemId);\n\n\\CPullWatch::AddToStack('VENDOR_ITEM_' . $itemId, [\n    'module_id' =&gt; 'vendor.module',\n    'command' =&gt; 'item.updated',\n    'params' =&gt; ['id' =&gt; $itemId],\n]);\n</code></pre>\n<ul>\n<li><code>CPullWatch::Extend($userId, $tags)</code> — refresh subscriptions (also used from pull controllers/JS).</li>\n<li>Tag messages still go through <code>Event::add</code> under the hood.</li>\n</ul>\n<h2>JS Subscription Overview</h2>\n<p>Client global: <code>BX.PULL</code> (<code>PullClient</code>, extension <code>pull.client</code> / product core load). Subscribe:</p>\n<pre><code>const unsubscribe = BX.PULL.subscribe({\n    moduleId: 'vendor.module',\n    command: 'item.updated', // optional; omit to get all module commands\n    callback: (params, extra, command) =&gt; {\n        // update UI\n    },\n});\n\n// Watch tag (pairs with CPullWatch):\nBX.PULL.extendWatch('VENDOR_ITEM_' + itemId);\n</code></pre>\n<p><code>subscribe</code> returns an unsubscribe function. Alternative: <code>attachCommandHandler</code> with an object exposing <code>getModuleId()</code> and command methods.</p>\n<p>In BitrixVue apps (<code>bitrix-vue</code>), subscribe in <code>mounted</code> / setup and unsubscribe on unmount; keep <code>moduleId</code>/<code>command</code> identical to PHP <code>Event::add</code>.</p>\n<p>Queue helper extension: <code>pull.queuemanager</code> wraps <code>BX.PULL.subscribe</code> + <code>extendWatch</code> for list/grid sync patterns.</p>\n<h2>Push (Mobile)</h2>\n<p>Optional <code>push</code> / <code>pushParamsCallback</code> keys on <code>Event::add</code> enqueue mobile push via <code>CPushManager</code> when push is enabled (<code>CPullOptions::GetPushStatus()</code>). Treat as a separate channel from browser Pull commands.</p>\n<h2>Operational Notes</h2>\n<ul>\n<li>Parameters must be UTF-8; invalid encoding is rejected.</li>\n<li>Keep payloads small (IDs + flags); fetch heavy data via AJAX/REST after the event.</li>\n<li>Shared channel / guest modes depend on Pull options — verify before designing guest UX.</li>\n<li>Module may expose REST helpers (<code>Bitrix\\Pull\\Rest</code>, controller <code>config</code> for watch extend) when <code>restIntegration</code> is enabled in pull <code>.settings.php</code>.</li>\n</ul>\n<h2>Checklist</h2>\n<ul>\n<li><input disabled=\"disabled\" type=\"checkbox\"> <code>pull</code> module loaded; queue server enabled in environment.</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> Events use stable <code>module_id</code> + <code>command</code> names shared with JS.</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> Recipients are user IDs or valid channels; tags use <code>CPullWatch</code> consistently.</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> UI handlers unsubscribe / avoid leaks in SPA/Vue.</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> Pull not used as a durable job queue (use Messenger/agents).</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> Large data loaded on demand after the signal.</li>\n</ul>\n<h2>Related skills</h2>\n<p><code>bitrix-background-jobs</code>, <code>bitrix-vue</code>, <code>bitrix-extensions</code>, <code>bitrix-controllers</code>, <code>bitrix-rest</code>.</p>\n","files":[{"path":"SKILL.md","sizeBytes":5068,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
