Connect the payment methods in Shopify with the pay types in Specter.
Each row connects:
a Shopify Payment Method, and
a Specter Pay Type Identifier (a 2-character code, for example Klarna (K) or Swish (SW)).
Good to know
Type each payment method exactly as Shopify sends it – same spelling and same upper/lower case. A value that doesn't match is skipped without an error.
For more settings per payment method, see Payment Method Settings.
