Use flow filter to send data to Shopify Flow. It expects JSON payload as parameter. Payload needs to contain one of the following keys:

* customer\_id
* product\_id
* order\_id

Sample usage could look like this:

```
{% json payload %}
	{"customer_id": 5287014039740}
{% endjson %}

{% assign result = payload | flow %}
```

Next custom with provided ID is automatically loaded in Shopify Flow:
