<p class="card-subtitle mb-2 text-muted">Everything you need to integrate with external services like n8n.</p>
</div>
<div class="card-body">
<p>Webhooks are a powerful way for your application to send and receive information from other services in real-time. Here’s how they work in your CRM.</p>
<hr>
<h2 class="mt-4">Outgoing Webhooks</h2>
<p>Your application sends these webhooks when certain events happen. You can set the destination URL in the <a href="settings.php">Settings</a> page.</p>
<div class="card mt-3">
<div class="card-header bg-light">
<strong>Event: New Post Scheduled</strong>
</div>
<div class="card-body">
<p>This webhook is sent every time you schedule a new post in the <a href="scheduler.php">Scheduler</a>. It tells your external service (e.g., n8n) that a new post needs to be generated and published.</p>
<p><strong>Method:</strong> <code>POST</code></p>
<p><strong>Data Format:</strong> <code>application/json</code></p>
<h6>Example Payload:</h6>
<pre class="code-block-dark p-3 rounded"><code>{
"event": "new_post_scheduled",
"channel_identifier": "@my_telegram_channel",
"post_text_idea": "A post about morning coffee",
"scheduled_at_utc": "2025-10-28 14:30:00",
"post_id": 123
}</code></pre>
<h6>Field Descriptions:</h6>
<ul>
<li><code>event</code>: The name of the event (always "new_post_scheduled").</li>
<li><code>channel_identifier</code>: The public URL or @name of the target channel (e.g., "@my_channel" or "t.me/joinchat/...").</li>
<li><code>post_text_idea</code>: The initial text or idea you entered in the scheduler. Your n8n workflow should use this as a prompt for AI text generation.</li>
<li><code>scheduled_at_utc</code>: The planned publication time in UTC.</li>
<li><code>post_id</code>: The unique ID of the post in this CRM, which can be used for status updates.</li>
</ul>
</div>
</div>
<hr class="my-5">
<h2 class="mt-4">Incoming Webhooks</h2>
<p>Your application can also receive webhooks from other services. This is how your n8n workflow reports back on the result of a publication.</p>
<p>The unique and secure URL for incoming webhooks is available on the <a href="settings.php">Settings</a> page.</p>
<div class="alert alert-warning" role="alert">
<strong>Important:</strong> The payload for incoming webhooks is different from the outgoing ones. You must send a status update, not the original event data.
</div>
<div class="card mt-3">
<div class="card-header bg-light">
<strong>Purpose: Report Publication Status</strong>
</div>
<div class="card-body">
<p>After your n8n workflow attempts to publish a post, it **must** send a webhook back to your CRM to report the outcome. This allows the system to update the post's status from "pending" to "published" or "failed".</p>
<p><strong>Method:</strong> <code>POST</code></p>
<p><strong>Data Format:</strong> <code>application/json</code></p>
<h6 class="mt-4">Required Fields:</h6>
<ul>
<li><code>post_id</code> (integer): The ID of the post this update refers to. <strong>This is mandatory.</strong></li>
<li><code>status</code> (string): The outcome. Use <code>published</code> for success or <code>failed</code> for an error.</li>
</ul>
<h6 class="mt-4">Example Payload (Success):</h6>
<p>This is the minimal payload you need to send for a successful publication.</p>
<pre class="code-block-dark p-3 rounded"><code>{
"post_id": 123,
"status": "published"
}</code></pre>
<h6 class="mt-4">Example Payload (Error):</h6>
<p>If something goes wrong, send this payload. You can include an optional <code>details</code> field for error messages.</p>
<pre class="code-block-dark p-3 rounded"><code>{
"post_id": 123,
"status": "failed",
"details": "Telegram API error: Chat not found."
}</code></pre>
