STEP 3 : Edit the composer.json file and add the following section to specify:
- Module: “magento/module-payment”
- Title: “MAGETWO-56934: Checkout page freezes when ordering with Authorize.net with invalid credit card”
- Path to patch: “patches/composer/github-issue-6474.diff”For example:
"extra": {
"composer-exit-on-patch-failure": true,
"patches": {
"magento/module-payment": {
"MAGETWO-56934: Checkout page freezes when ordering with Authorize.net with invalid credit card": "patches/composer/github-issue-6474.diff"
