Payment Created and Order Created Webhooks Don't Carry Customer ID Like API Says It Does

Questions
1

Every time a customer creates an order/payment, I am looking to get the order_id and custoer_id for the associated order/payment. The API documentation says the order.created and payment.created events should carry this data. I only see order_id and not customer_id and I am not sure why. Here is an example for payment.created and order.created events respectively:

==============================
PAYMENT HAS BEEN CREATED
Full payment created body:
{
  merchant_id: 'QMQ16MVGWH93N',
  type: 'payment.created',

  data: {
    type: 'payment',

    object: { payment: [Object] }
  }
}

CUSTOMER ID: undefined

UPDATE: I was reading online and saw that customer ids may not always appear in payment created/order created. This begs the question: how do I find the customer for a specific order. I am trying to send them an email after they made an order.

I am using a square checkout URL for my customers to make orders. So I need a customer_id generated and associated with an order whenever they make a purchase.

Customers that pay with the Square generated payment links will have a customer associated to them cause that information is collected at the time of payment. It’s payments like cash and external payments that may not have a customer associated to it. Card payments will since we have more information and can match cards that have already been used on the sellers account. :slightly_smiling_face:

Oh ok so you’re saying that it will have a customer ID once a customer checks out with a credit card? I am using square generated URLs for payments. Here is an example of one:

Yes, when they checkout with a credit card the payment will have a customer_id. :slightly_smiling_face:
