Best Strategy for consolidating webhook payloads from different topics

If I have a 2 webhook topics, where one depends on the other (from a third party system, which I cannot modify)

eg payload 1 (order)

{
  id: 12,
  order_number: 45666
  ...
}

payload 2 (customer)

{
   order_id: 12
   ...
}

Now assuming the third party uses queues to manage their webhooks you cannot assume that the webhooks will arrive in correct order, more-so, they might arrive at the same time on your concurrent server

these are the 2 solutions I've come up with

Solution 1 Ignore the customer webhook completely and query the customer API endpoint when the webhook arrives

pros - will work in sequence

cons - could hit API limit very quickly if there is a surge in orders

Solution 2 Requeue the customer webhook after a timer has hit , say intervals of 5, 20 100, 500 seconds

pros - requires less API calls

cons - could fail if the webhook is never delivered

Can someone with experience dealing with this let me know if either is a good solution or their is a better one out there?
