MERCHANT.ONBOARDING.COMPLETED webhook not triggering

[referralhub]

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 successfully triggered. This is the doc I'm referring to: https://developer.paypal.com/docs/multiparty/seller-onboarding/before-payment/#link-setupwebhooks

Hi @referralhub ,

Thank you for posting to the PayPal Merchant Community.

Normally after the account is onboarded successfully, a webhook is triggered. Since you are stating you are receiving other webhooks, but not this specific one, there is a possibility that the webhook was either not generated or it is currently delayed.

You can check your webhooks in the developer dashboard to see if it was created:

• Log into the developer dashboard at https://developer.paypal.com
• Hover over Event Logs
• Click Webhook Events
• You can search with any of the details to see if a webhook was generated

If the webhook was not generated, and you did successfully onboard the seller, you can open a ticket to Merchant Technical Support to research this issue further.

• Go to https://paypal.com/mts
• Click Contact Us
• Click Log In with PayPal
• Log in with your PayPal email and password
• Fill in the details
• Ensure that you include your partner app client id, debug ids, and any additional information

Thank you,

Jennifer
