Tracking information for eBay and PayPal

[Bot123]

So recently I found this supplier that has low competition and high margins for me . The way they provide tracking is different however . They do not use the normal big ones for example : Hermes or parcel force , they have their own tracking website . My question is if a buyer opens a claim and I provide this tracking information which takes you to their own independent tracking website ( which is similar to others as it shows delivery date and journey ) will I be good to use it like other tracking and will I win the case ?
And with this tracking information will eBay and PayPal accept it ? I have seen other 3rd party tracking being used for example blue care express

I know that the bluecareexpress tracking numbers can be verified and user for eBay

You should be OK, as long as its a genuine courier company you use.
