Hi there,
for some time now, we are observing that the ‘shipping_rates.json’ GET endpoint of the Ajax Cart API is causing an undesired automatic auto completion of the shipping address fields (city and zip code) in the checkout, and this is something that didn’t happen before. The use of this endpoint is documented at:
On the one hand, the behavior described above is not documented. On the other hand, and technically speaking, a GET request should never have side effects.
Please, can you take a look?
Kind regards.
