* Add supports data to payment methods abstractions. Implement in Stripe.
* Add capabilities to the payment gateway.
* Payment requirements in cart schema.
* Supported features format update.
* Formatting.
* Check required payment features.
* Refactor capabilieties check.
* No need for the cart parameter.
* Allow external modifiacation of features capability.
* Use ExtendRestApi to inject payment requirements into cart endpoint.
* Simplify the code.
* Enable more integrations.
* Enable Stripe payment request.
* Move the filter to a more correc location.
* Add features check.
* Update typedefs and documentation.
* Update tests with new functionality.
* Style fixes.
* Remove savePaymentInfo check when displaying payment methods
This is because the savePaymentInfo is derived from whether the save payment method checkbox shows. This check doesn't make sense to do because it's not a good indicator of whether the payment method is enabled. Subscriptions for example hides the checkbox because it is implied that the method will be saved. We should instead rely on the server-side to only send permitted saved payment methods.
* Add safely_get_request_payment_method
This will allow us to try to get the payment method if it was passed in the request, but will default to an empty string if not. This is different to get_request_payment_method because it doesn't throw any errors. We need it to be different because get_request_payment_method is used when the order definitely needs payment (so a normal checkout scenario, vs. a £0 subscription checkout)
* Add action to update order meta when checking out
This is needed because some extensions rely on this action to add their information to the metadata of order items.
* Remove safely_get_request_payment_method
This is no longer needed.
* Remove @since from experimental hook
* Add PHPDoc for new update_order_meta hook
* Document use of experimental hook
* Reinstate the check for allowing saved cards
* Add method to Stripe integration to determine if saved_cards is enabled
* Add new field to get_payment_method_data
This adds displaySavePaymentMethodCheckbox which will be used to determine if the checkbox to save payment methods should display.
* Add displaySavePaymentMethodCheckbox option to client
This will determine whether the "Save payment information" checkbox will be displayed.
* Add requiresSaving option to Stripe payment method data
This is informed by the saved_cards option and the result of the wc_stripe_display_save_payment_method_checkbox filter.
* Rename displaySavePaymentMethodCheckbox to requiresSaving & fix logic
* Revert negation on display_save_payment method_checkbox filter & rename
We are going to rename the properties we use to determine whether saved cards are shown, or whether the save payment method checkbox is shown, so that their names are more descriptive of what they are for.
* Rename allowSavedCards and requiresSaving in Stripe integration
* Rename savePaymentInfo&requiresSaving to showSavedCards & showSaveOption
This is so we can hide the checkbox independently of hiding the saved payment methods.
* Show deprecated message if payment methods use savePaymentInfo
This is because we are leaving it in to enable backward compatibility but payment methods registering using this should be informed of the change in case it gets removed.
* Update Stripe typedefs and keys of supports object
* Show customer payment methods if showSavedCards is true on the method
* Make PaymentMethodTab accept showSaveOption prop
This will allow us to show the save checkbox only if the payment method says it should be shown.
* Update tests to use new keys in supports when reg'ing payment methods
* Add optional chaining when validating payment method config
This makes the code a little tidier :)
* Update assets/js/blocks-registry/payment-methods/payment-method-config.js

* Correct docblock description
* Sync shipping address changes with billing data
* Update inline documentation
* Revert address sync because it fails when shipping is disabled explicitely
* Avoid loading shipping address from customer is shipping is disabled
* Rather than update order from the wc/store/checkout request, update the customer object
This is turn is synced to order, but also allows the cart calcultions to use the posted data. This means that taxes will be updated based on address data even if not displayed on the checkout.
* Add action that combines billing and shipping updates
* Add route for updating billing and shipping address
* Sync billing data to server on change
* Shared constants for billing data
* Skip address update if missing country

* convert eslint config to use @woocommerce/eslint-plugin
- removes unnecessary dependencies
- adds e2e-tests/specs to eslint ignore (they are automatically generated)
- turns off rules that will be handled in subsequent pulls (to avoid a mammoth changeset for review).
- NOTE: prettier config needs left in because of a bug with the existing version of `@wordpress/eslint-plugin` pulled in (fixed in https://github.com/WordPress/gutenberg/pull/25068) so I left the file for now.
* prettier fixes.
* remove obsolete plugin and fixes for eslint update
This branch brings an update to eslint which also changes some syntax with plugins. So this commit:
- fixes featuer-flag plugin syntax.
- removed obsolete dependency-group plugin (which is now in the `@woocommerce/eslint-plugin` configuration.
* add to-do comment
* fixes for test runs
- this also converts our e2e test scripts to use `wp-script test:e2e`, an advantage of this is it will load CHROMIUM on demand for the e2e test run.
* fixes for test runs
- this also converts our e2e test scripts to use `wp-script test:e2e`, an advantage of this is it will load CHROMIUM on demand for the e2e test run.
* include prettier alias as a dependency
This has to be done because prettier is installed with storybook and thus the alias setup in `@wordpress/scripts` is over-ridden by the storybook import.
* another attempt at e2e-test-fix
* add some debugging and temporarily just add one e2e config test for travis
* more debugging
* try installing full puppeteer and see if fixes
* fix package-lock?
* setupSettings separately from other fixture loading
* add debugging of files
* add another console.log (hopefully trigger travis)
* split out blockPage creation to it’s own as well
* fixed! remove debugging and re-enable travis configs for entire test suite
* fix config and rename e2e-tests to e2e
- fixes the failing product-search test
- tests/e2e-tests was redundant, I changed to `tests/e2e` (this follows a file pattern change made in woocommerce core as well).
* add todo for some eslint properties
* remove unnecessary early function execution
* revert earlier commit and remove duplicate call to createBlockPages
* remove generic icons from Cheque & Stripe CC payment methods
* remove icon prop from PaymentMethodLabel - no longer supported:
- icons should only be used for recognisable brands
- generic icons (e.g. credit card) are not recommended
* Revert "remove icon prop from PaymentMethodLabel - no longer supported:"
This reverts commit 1990028a6c98b82750fb917ff3086dbe022ef41d.
* enqueue and respect merchant option for disabling stripe express pay
* don't even register express payment method if merchant has disabled it
* add StripeServerData.allowPaymentRequest to typedef
* Fix Credit Card input font size in some themes
* Fix spacing between credit card icon and input label
* Fix min-width of credit card input fields
* Improvements to the way credit card input fields are resized
* Simplify min-width
* stub out COD payment method for checkout block
* consistently use sentence case for (default) payment tab labels
* expose COD `enable_for_virtual` option to client
* correct docblock return value comment Stripe::get_inline_cc_form()
* allow merchant to disable COD payment for virtual/downloadable orders
* tweak canMakePayment dev docs - add cart-dependent example use case
* only allow (show) COD if initially-selected shipping method(s) allow
* tweak `canMakePayment` payment extension API docs
* use $VID:$ substitution for `@since` version in new payment methods
* use FILTER_VALIDATE_BOOLEAN for payment method boolean options
* use more semantic `some` when hunting for COD-unsupported shipping
* clarify `canMakePayment` API docs
* re-select payment method if selected method disappears (e.g. COD) +
+ factor out early return into separate if at top for clarity
* allow payment methods to disable based on shipping or other factors:
- renamed 'initialized' array 'available' to match primary purpose of
`canMakePayment` api - whether payment method should be available
- trigger refresh of available payment methods when shopper chooses
different shipping method
- rename resolveCanMakePayments => refreshCanMakePayments
- tweaked some variable names and scope for clarity
- added comments to clarify things
Note this should not affect behaviour yet - no existing payment methods
use this new feature. COD payment method will need this - woocommerce/woocommerce-blocks#2831
* optimise refreshCanMakePayments:
- useShallowEqual to avoid unnecessary call when shipping methods have
not actually changed (but object value has)
* replace ("set") payment methods in store, was appending:
- payment methods may come and go depending on cart/checkout state
- the previous SET action appended provided payment methods to the
collection
- this prevents dynamic payment methods e.g. COD from being able to hide
i.e. disable
* cache test payment request to avoid unnecessary stripe API calls:
- in the canMakePayment callback there's a test payment to determine if
chrome pay/apple pay is set up and available
- canMakePayment is now called multiple times as checkout state changes
- now the results of the test payment are stored in variable, and
returned on subsequent calls
* set init flag to avoid additional attempts to init stripe API:
+ tweak naming of init flag
* stubs for bank transfer payment method
* allow merchant to disable BACS payment method
* show customised BACS title & description in checkout
* re-add entry point for BACS payment method (lost in rebase)
* Remove todos for colors (see woocommerce/woocommerce-blocks#1331)
* remove todo for payment method express payments placeholder
No placeholder is needed because we don’t want to show this at all if there are no payment methods setup (or initialized based on `canMakePayment`). The payment methods step will have instructions in the editor for users to setup their payment methods.
So this todo was invalid.
* Remove todo comment for useStoreOrder (see woocommerce/woocommerce-blocks#2555)
* remove obsolete todos for usePaymentMethodInterface
* changed todo into a Note for the useQueryState tests
With focused work happening on tests, this is better as a note that can be picked up when this file is touched again.
* remove obsolete todo from payment method registration validation
* remove todo covered by created issue (see woocommerce/woocommerce-blocks#2166)
* remove obsolete todo for stripe utils
* Convert todo to a Note for Checkout Block php registration
For now, I think having the comment block noting what is happening here is sufficient. Whether or not we extend the blocks to cover the other endpoints is something that will surface in future planning and putting in an issue right now coudl be premature (and likely just land the issue in the icebox)
* Remove todo related to ReserveStock covered by woocommerce/woocommerce-blocks#2556
* Remove todo in AbstractRoute covered by issue in WooCommerce project
see https://github.com/woocommerce/woocommerce/pull/26219 for the issue.
* Convert todo to note for wp_version check in Library class
* fix dependencies
* refactor stripe payment-request to extract things into smaller units
- adds/fixes typedefs
- fixes dependencies
- improves logic.
* implement memoizing for functions.
* if same shipping address is selected, just call updateWith immediately
* add separate handler for failed shipping rate retrieval
* improve logic around shipping rate fail/success status
* add notice suppression logic to store notices.
- this is implemented in checkout processor to suppress notices when express payment methods are active.
* add error detection for shipping address errors and update the shipping status accordingly
* update type-def
* set billingData before shippingData
This is needed because of the shipping data and billing data sync logic in use-checkout-address.
* have to tighten dependencies to prevent unnecessary firing
With us now adding error status setters for shippping, the potential for the shipping status changes to trigger the effect went up. So tightening the dependencies to only the stati we care about prevent unnecessary effect calls.
* refactor event handlers to be named and remove all listeners.
This is an undocumented api on the stripe `paymentRequest.on` return value, but I’m trusting it will be relatively stable for this api.
The need for this is caused by the fact that without it, the listeners are re-registered on the paymentRequest event everytime the paymentRequest modal is closed and reopened.
* fix typo in doc block
* expose a allowSavedCards option to JS on stripe settings data
* hide 'save my card' checkbox if merchant disables saved cards
* use stripe allowSavedCards option to control "Save my card" checkbox
* (linter) remove unnecessary useEffect dependency:
- stripePromise const is defined outside component, so hook doesn't
depend on it
* clarify comment about saved cards and supports( tokenization )
* correct comment about save card merchant option - doesn't affect paying with previously saved payment methods
* use true boolean value for stripe allow saved cards setting:
previously was using woo option `yes no` style, other JS settings all use true bool
Co-authored-by: Darren Ethier <darren@roughsmootheng.in>
* fix client side check now `allowSavedCards` is true boolean
Co-authored-by: Darren Ethier <darren@roughsmootheng.in>
* always default "save my card for next time" checkbox to unchecked:
This is based on the previous checkout behaviour.
I.e. the shopper has to actively opt-in to save their card.
* Implement "save payment method for next purchase" in checkout:
- send "save card" option using existing post key
- wc-stripe-new-payment-method
- comment out inappropriate use of "save" when using a saved card (tbc)
* don't hard code the payment gateway name in 'save payment method' key
* refactor "save payment info" checkbox so payment methods can opt-in:
- Add options.allowSavePaymentToken to payment method
registration / config.
- Opt-in in Stripe CC, it allows saved cards.
- Remove render of "save my card" checkbox from Stripe CC UI component.
- Render "save my card" checkbox automatically in payment method tab
(based on allowSavePaymentToken option).
+ todo/follow up comments
* rejig "save my payment method" behaviour so it's generic:
- Any payment method that supports "save" can opt-in:
- options.allowSavePaymentToken = true/false
- handle `wc-XXX-new-payment-method` key server side to persist
- Add support in payment context/state reducer for storing checkbox
state, expose value and action via context
- Convert state flag to appropriate API key/value in payment processor
- Remove previous stripe-specific implementation
+ bonus add comment to payment context about preserving state in
PRISTINE action
* rename payment method "allow save" option, more consistent with UI
* remove last vestiges of gateway-specific "save card" impl:
- No need to pass CheckboxControl to payment methods; checkbox is
now handled automatically by checkout.
- Remove shouldSavePayment prop passing through various layers of
stripe payment processing code. (Now handled in context/processor.)
* change new option property name and shape. Also adds validation.
* update type-defs
* use more reliable `activePaymentMethod` for saved payment method
Co-authored-by: Darren Ethier <darren@roughsmootheng.in>
* add typedefs for store notice context
* improve useStoreNotices hook so returned interfaces are fairly constant
* fix dependencies, defaults, and add types
* fix dependencies
* fix dependencies
* improve functions exposed on validation context so they are more constant
* fixing dependencies
* normalize tokenId to string everywhere
Assuming the token is a number is a bad idea because it is feasible that source for some payment methods could be a string. Also when retrieved as an input value, the id will be a string anyways.
* refactor to move payment processing into it’s own effect
- this is the first step in trying to improve the createSource behaviour.
* memoize setValidationErrors so onPaymentProcessing event effect doesn’t re-run unnecessarily.
* Update assets/js/payment-method-extensions/payment-methods/stripe/credit-card/use-payment-processing.js

* implement returning paymentMethodId from payment-request-express
* include paymentMethodId in stripe cc success return value
* include paymentMethodId in cheque success return value
* add active payment method setting and handling via checkout

- onClose when the express payment interface is closed (cancelled etc).
* don’t expose setActivePaymentMethod on the payment method interface
* remove/fix artifacts from earlier iterations of the pull
* rename `id` property to `name` property for payment method registration

This reverts commit c38a05b63626dfc1336c7bb0e86417b798a803d6.
* Revert "add processedPaymentMethodId to payment method data context state"
This reverts commit 3d7923e7297f3c76efde536d26eaf68464ba9583.
* improve isSuccess response check and variable name
* implement paymentMethodId config option
* doh php ain’t javascript
* add missing dependency from rebase
* use cart data to provide country and currency_code
* remove files that likely got added back in from a bad rebase.
* modify canMakePayment config property so it must be a function
* Feed cart data to registered payment methods `canMakePayment` function.
This can then be used by payment methods for determining whether to show the payment method or not.
* implement new canMakePayment signature for cheque
Now canMakePayment doesn’t need to be a promise (payment method registry will handle wrapping all values in a promise to treat them as promises.
* implement canMakePayment as a function
* add logic allowing payment method to be overridden via payment data in request
* hook in to trigger server side processing of stripe payment request
* improvements to shipping data context
- memoize event emitters
- split up emitted events (reduces how often events trigger)
- Include whether rate is being selected in exported data.
* expose `isSelectingRate` value to payment method interface
* fix typo in shipping emitters for emitter type
* include setting of shipping data in payment method success status call
- this also requires changing the nested order of providers in checkout provider
* fix priority logic for event emitters.
- lower priority is supposed to fire before higher priority.
* normalize postal code for comparisons
* move normalize functions into stripe-utils folder
* refactor stripePromise so that it provides a specific instance to each payment method.
This also provides it as a prop to the pm components.
* renadme apple pay express to payment request express
This adds full support for the stripe payment request api instead of just applePay (so GooglePay, MicrosoftPay and ApplePay are now supported).
Also adds numerous fixes to internal logic.
* add handling to skip core checkout validation logic if express payment method is handling payment
Express payment methods have their own internal validation so this removes the need for checkout validating fields. This is also necessary because checkout validation breaks the flow when making a payment using express payment methods because of the order of the flow for these methods.
* splitting out emmitter effects for checkout and improving logic
Splitting up effects limits the potential for firing off emitters more than needed.
* remove unnecessary ref definitions
* fix on cancel action erroring for payment request modal
* ensure unique stripe object for component and canPay
* set default total label if one isn’t configured on the server
* fix order of state changes
* simplify condition
* remove unnecessary dependency
* normalize to uppercase too
* simplify can make payment conditional
* update comment blocks
