Technical Q&A

Topic summary

A developer is encountering GraphQL mutation errors while attempting to complete a Shopify checkout using the checkoutCompleteWithCreditCardV2 mutation.

Primary Issues:

  • The mutation rejects the vaultId parameter at the field level
  • The CreditCardPaymentInputV2 input object doesn’t accept a creditCard argument
  • A required vaultId argument of type String! is missing from the CreditCardPaymentInputV2 object

Key Problems:

  • Incorrect mutation structure with misplaced or unsupported parameters
  • The developer is unsure how to properly create or obtain a vaultId
  • Multiple schema validation errors indicate the payment input object is malformed

Current Status:
The question remains unanswered with no solutions provided. The developer needs guidance on the correct mutation syntax and the process for generating/obtaining a valid vaultId for Shopify’s checkout API.
