I'm trying create a listener for the MERCHANT.ONBOARDING.COMPLETED in my sandbox environment. After the user goes to the return url specified in "partner_config_override/return_url" of the /v1/customer/partner-referrals endpoint, the webhook isn't being triggered, even though I received
{"success": {"merchant_id": "GKH5BSPUXXB3Y", "tracking_id": "abcd", "products": [{"name": "EXPRESS_CHECKOUT", "status": "ACTIVE"}], "payments_receivable": true, "primary_email_confirmed": true}}
when I call this endpoint to check if the seller has been onboarded: /v1/customer/partners/{partner_merchant_id}/merchant-integrations/{seller_merchant_id}. Are there any other steps I need to take in order for the MERCHANT.ONBOARDING.COMPLETED webhook to be triggered? The CUSTOMER.MERCHANT-INTEGRATION.SELLER-ONBOARDING-STARTED is being triggered and I do receive POST requests for that.
