# Code Glue

Attach short PHP snippets per webhook+trigger to enrich payloads before dispatch.

Write a pre-dispatch PHP snippet in the admin panel and attach it to a webhook+trigger combination. The snippet runs after payload mapping and can read WordPress data, look up post meta, call internal functions, or reshape fields without touching theme or plugin files.

## Available variables

`$payload` — the mapped payload array. `$args` — shortcut to `$payload['args']`, the original hook arguments.

## Shorthand syntax

Curly-brace placeholders resolve to array access for any variable: `{{ $args.0.field }}` → `$args[0]['field']`, `{{ $payload.key }}` → `$payload['key']`.

## Return value

Must `return $payload;` — the returned array replaces the payload before dispatch.

/ Examples

Look up and inject a HubSpot deal ID from post meta

```
// Available: $payload (mapped array), $args ($payload['args'])
$order_id = $payload['order_id'] ?? 0;
$hs_deal_id = get_post_meta( $order_id, '_hs_deal_id', true );
$payload['hs_deal_id'] = $hs_deal_id;
return $payload;
```
