We are querying Transactions associated to Shopify Orders via GraphQL API.
The sole purpose is to extract Authorization Keys and validate them against the payment providers directly.
However, with increasing transaction volumes, the GraphQL throttle practically limits the approach to around 100 to 200 transactions every 5 to 10 seconds - which makes it virtually impossible to ever catch up with the number of orders.
What is your recommended way to query Transactions?
Do you have experience with the Analytics API leveraging on Shopify App Bridge? (That's the one I have not tried yet.)
