I am trying to onboard partner merchants through the REST api, and I can log-in and generate a sign-up link successfully. Now I want to find out whether the merchant has completed onboarding and the approach I was planning to use was to make an API call as Documented in the "track seller onboarding status" page. The problem is that whatever I put into that call I just seem to get a 404 response back. The documentation says: You can also query it directly by the tracking ID you specified in the Partner Referrals call by calling GET /v1/customer/partners/partner_id/merchant-integrations?tracking_id={tracking_id} I assumed that here it when it says "partner_id" I should be using my Merchant Id, but I've tried it both ways, calling GET https://api-m.sandbox.paypal.com/v1/customer/partners/ABC123DEF456/merchant_integrations?tracking_id=my-tracking-id with my Authorization: Bearer ... authentication token and always returns a 404. I think I have tried with every merchant Id in all my partner companies, so as far as I know it should be working with one of them. Is this because I'm trying to access a v1 endpoint with a v2 authorization code? I don't see any record of the calls on my developer dashboard at all, but I do see the other calls I have made, both successful and unsuccessful.
