shopify_payments_account_id always NULL

[Anonymous]

Hi All,

I have a test store with payment gateway in test mode. 

My checkout api is aways returning shopify_payments_account_id null

I have reached support for store as suggested in some of these community messages, they suggest  reach partner program. I have posted in discord, no response.

This seems like a basic first step for app development. Yet i see no proper documentation. 

Can someone point me to the right steps/proper documentation please?
