Apple Wallet Pass AutoUpdate – without app

I have successfully created an Apple pass using PHP.
The pass is added to the Apple wallet successfully.

Now, I have to update the pass with a new value for one of the parameters in the pass. How do we update the value? Please refer to a sample PHP script for the same.

I have checked the below sites, Here, they Mentioned only the input and output, as per the document I received the push token,
What should I do after getting the push token?
