I want to extend graphql mutation so that I can make one field optional in the input params in braintree module. Below is the file path
Core GraphQL Schema File: vendor\paypal\module-braintree-graph-ql\etc\schema.graphqls
Input Params: BraintreeInput
If you see there are payment nonce mandatory in the Input params. We have requirement to by pass that and make payment nonce optional. I have written my own module for the same. I just want to know how I can do that?
Copy the following code into your module schema.graphql and remove the ! exclamation mark (!).
input BraintreeInput { payment_method_nonce: String! @doc(description:"The one-time payment token generated by Braintree payment gateway based on card details. Required field to make sale transaction.") is_active_payment_token_enabler: Boolean! @doc(description:"States whether an entered by a customer credit/debit card should be tokenized for later usage. Required only if Vault is enabled for Braintree payment integration.") device_data: String @doc(description:"Contains a fingerprint provided by Braintree JS SDK and should be sent with sale transaction details to the Braintree payment gateway. Should be specified only in a case if Kount (advanced fraud protection) is enabled for Braintree payment integration.") } Make Sure you add the following to your module.xml
<sequence> <module name="PayPal_BraintreeGraphQl"/> </sequence>
