Code Glue

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;
