It looks like when we are sending the webhook we are getting a 405 status code back and an long HTML response.
Any chance the endpoint might not be prepared to receive the request?
Suppose a PO already received 4 qty from same item(i.e. SKU), if i want to receive 2 more qty from same item(i.e. SKU). then in this case how many items should i receive with the webhook (i.e. should i receive 2 qty or 6 qty)?
please confirm i need to manage it with my PO receiver.
