Custom data from paypal JS button into webhook

Question

The JavaScript PayPal button, http://paypal.github.io/JavaScriptButtons/ allows custom data to be sent in the data-custom field.

When using IPN, these data are clearly visible and usable.

However, I don't find any mention of custom data in the webhook documentation; I would expect the "Sale Completed" event to receive something about custom data.

So my question is twofold:

1. Has anyone managed to get the data and knows what field contains them?
2. Is there a way to simulate this, given the webhook simulator does not allow any field to be entered?

Answer 1

Webhooks do not support any custom data for simulator. Simulator provides a sample of payload for an event. It does not allow any other data field except URL/EventType. If you want to use the custom data you may use them and don't want to use a live account for testing, you can try it with a sandbox account and go through flow for the Webhook event type for which you want to send custom data.

Also sample for PAYMENT.SALE.COMPLETED for your reference:
