        string
    $baseReturnUrl

$billingProfile

The profile configured to show on the billing form.


    protected
        int|string
    $billingProfile

Currently only the pseudo-profile 'billing' is supported but hopefully in time we will take an id and load that from the DB and the processor will be able to return a set of fields that combines it's minimum requirements with the configured requirements.

Currently only the pseudo-processor 'manual' or 'pay-later' uses this setting to return a 'curated' set of fields.

Note this change would probably include converting 'billing' to a reserved profile.

Return url upon failure (offsite processors).


    protected
        string
    $cancelUrl

Parameters

$form : CRM_Core_Form

Return values

bool —

Should form building stop at this point?

    public
                    checkConfig() : string

Return values

doCancelRecurring()

Cancel a recurring subscription.


    public
                    doCancelRecurring(PropertyBag $propertyBag) : array<string|int, mixed>

Payment processor classes should override this rather than implementing cancelSubscription.

A PaymentProcessorException should be thrown if the update of the contribution_recur record should not proceed (in many cases this function does nothing as the payment processor does not need to take any action & this should silently proceed. Note the form layer will only call this after calling $processor->supports('cancelRecurring');

A payment processor can control whether to notify the actual payment provider or just cancel in CiviCRM by setting the isNotifyProcessorOnCancelRecur property on PropertyBag. If supportsCancelRecurringNotifyOptional() is TRUE this will be automatically set based on the user selection on the form. If FALSE you need to set it yourself.

Parameters

$propertyBag : PropertyBag

Return values

array<string|int, mixed>

doPayment()

Submit a payment using Advanced Integration Method.


    public
                    doPayment(array<string|int, mixed>|PropertyBag &$params[, string $component = 'contribute' ]) : array<string|int, mixed>

Get billing fields required for this processor.


    public
                    getBillingAddressFields([int $billingLocationID = NULL ]) : array<string|int, mixed>

We apply the existing default of returning fields only for payment processor type 1. Processors can override to alter.

Parameters

$billingLocationID : int = NULL

Return values

array<string|int, mixed>

getBillingAddressFieldsMetadata()

Get form metadata for billing address fields.


    public
                    getBillingAddressFieldsMetadata([int $billingLocationID = NULL ]) : array<string|int, mixed>

getEditableRecurringScheduleFields()

Get an array of the fields that can be edited on the recurring contribution.


    public
                    getEditableRecurringScheduleFields() : array<string|int, mixed>

Some payment processors support editing the amount and other scheduling details of recurring payments, especially those which use tokens. Others are fixed. This function allows the processor to return an array of the fields that can be updated from the contribution recur edit screen.

The fields are likely to be a subset of these

'amount',
'installments',
'frequency_interval',
'frequency_unit',
'cycle_day',
'next_sched_contribution_date',
'end_date',
'failure_retry_day',

The form does not restrict which fields from the contribution_recur table can be added (although if the html_type metadata is not defined in the xml for the field it will cause an error.

Open question - would it make sense to return membership_id in this - which is sometimes editable and is on that form (UpdateSubscription).

Return values

array<string|int, mixed>

getForm()

Getter for payment form that is using the processor.


    public
                    getForm() : CRM_Core_Form

field metadata

getPaymentInstrumentID()

Return the payment instrument ID to use.


    public
                    getPaymentInstrumentID() : int

Note: We normally SHOULD be returning the payment instrument of the payment processor. However there is an outstanding case where this needs overriding, which is when using CRM_Core_Payment_Manual which uses the pseudo-processor (id = 0).

i.e. If you're writing a Payment Processor you should NOT be using setPaymentInstrumentID() at all.

supports()

Check if capability is supported.


    public
                    supports(string $capability) : bool

Capabilities have a one to one relationship with capability-related functions on this class.

Payment processor classes should over-ride the capability-specific function rather than this one.

bool

supportsEditRecurringContribution()

Checks if back-office recurring edit is allowed


    public
                    supportsEditRecurringContribution() : bool

    public
                    validatePaymentInstrument(array<string|int, mixed> $values, array<string|int, mixed> &$errors) : mixed

Payment processors should override this.

Checks to see if invoice_id already exists in db.


    protected
                    checkDupe(int $invoiceId[, int|null $contributionID = NULL ]) : bool

It's arguable if this belongs in the payment subsystem at all but since several processors implement it it is better to standardise to being here.

Parameters

$invoiceId : int: The ID to check.
$contributionID : int|null = NULL: If a contribution exists pass in the contribution ID.

Return values

bool —

True if invoice ID otherwise exists, else false

Does a server to server payment transaction.

Parameters

$params : array<string|int, mixed>: Assoc array of input parameters for this transaction.

array<string|int, mixed> —

the result in an nice formatted array (or an error object - but throwing exceptions is preferred)

doTransferCheckout()

Calling this from outside the payment subsystem is deprecated - use doPayment.


    protected

$params : array<string|int, mixed> = []

Return values

string

getBaseReturnUrl()

Get base url dependent on component.

getCurrency()

Get the currency for the transaction from the params.


    protected
                    getCurrency([mixed $params = [] ]) : string

Legacy wrapper. Better for a method to work on its own PropertyBag.

This code now uses PropertyBag to allow for old inputs like currencyID.

Parameters

$params : mixed = []

Return values

string

getDirectDebitFormFields()

Get array of fields that should be displayed on the payment form for direct debits.


    protected
                    getDirectDebitFormFields() : array<string|int, mixed>

                    getMandatoryFields() : mixed

getNotifyUrl()

Get the notify (aka ipn, web hook or silent post) url.


    protected
                    getNotifyUrl() : string

If there is no '.' in it we assume that we are dealing with localhost or similar and it is unreachable from the web & hence invalid.

Return values

string —

URL to notify outcome of transaction.

getPaymentDescription()

Get description of payment to pass to processor.


    protected
                    getPaymentDescription([array<string|int, mixed> $params = [] ][, int $length = 24 ]) : string

This is often what people see in the interface so we want to get as much unique information in as possible within the field length (& presumably the early part of the field)

People seeing these can be assumed to be advanced users so quantity of information probably trumps having field names to clarify

Parameters

$params : array<string|int, mixed> = []
$length : int = 24

Return values

string

getReturnFailUrl()

Get URL to return the browser to on failure.


    protected

    protected
                    setStatusPaymentPending(PropertyBag|array<string|int, mixed> $params) : array<string|int, mixed>

Parameters

$params : PropertyBag|array<string|int, mixed>

Return values

array<string|int, mixed>

supportsAccountLoginURL()

Checks if payment processor supports an account login URL TODO: This is checked by self::subscriptionURL but is only used if no entityID is found.


    protected
                    supportsAccountLoginURL() : bool

TODO: It is implemented by AuthorizeNET, any others?

Return values

bool

supportsBackOffice()

Are back office payments supported.


    protected
                    supportsBackOffice() : bool

e.g paypal standard won't permit you to enter a credit card associated with someone else's login. The intention is to support off-site (other than paypal) & direct debit but that is not all working yet so to reach a 'stable' point we disable.

Return values

bool

supportsCancelRecurring()

Does this processor support cancelling recurring contributions through code.


    protected
                    supportsCancelRecurring() : bool

If the processor returns true it must be possible to take action from within CiviCRM that will result in no further payments being processed. In the case of token processors (e.g IATS, eWay) updating the contribution_recur table is probably sufficient.

Return values

bool

supportsCancelRecurringNotifyOptional()

Does the processor support the user having a choice as to whether to cancel the recurring with the processor?


    protected
                    supportsCancelRecurringNotifyOptional() : bool

If this returns TRUE then there will be an option to send a cancellation request in the cancellation form.

This would normally be false for processors where CiviCRM maintains the schedule.

Return values

bool

supportsChangeSubscriptionAmount()

Does this processor support changing the amount for recurring contributions through code.


    protected
                    supportsChangeSubscriptionAmount() : bool

If the processor returns true then it must be possible to update the amount from within CiviCRM that will be updated at the payment processor.

Return values

bool

supportsFutureRecurStartDate()

Should the first payment date be configurable when setting up back office recurring payments.


    protected
                    supportsFutureRecurStartDate() : bool

We set this to false for historical consistency but in fact most new processors use tokens for recurring and can support this

Return values

bool

supportsLiveMode()

Are live payments supported - e.g dummy doesn't support this.


    protected
                    supportsLiveMode() : bool

Return values

bool

supportsMultipleConcurrentPayments()

Can more than one transaction be processed at once?


    protected
                    supportsMultipleConcurrentPayments() : bool

In general processors that process payment by server to server communication support this while others do not.

In future we are likely to hit an issue where this depends on whether a token already exists.

Return values

bool

supportsNoEmailProvided()

Does the processor work without an email address?


    protected
                    supportsNoEmailProvided() : bool

The historic assumption is that all processors require an email address. This capability allows a processor to state it does not need to be provided with an email address. NB: when this was added (Feb 2020), the Manual processor class overrides this but the only use of the capability is in the webform_civicrm module. It is not currently used in core but may be in future.

Return values

bool

supportsPreApproval()

Does this processor support pre-approval.


    protected
                    supportsPreApproval() : bool

This would generally look like a redirect to enter credentials which can then be used in a later payment call.

Currently Paypal express supports this, with a redirect to paypal after the 'Main' form is submitted in the contribution page. This token can then be processed at the confirm phase. Although this flow 'looks' like the 'notify' flow a key difference is that in the notify flow they don't have to return but in this flow they do.

Return values

bool

supportsRecurContributionsForPledges()

Can recurring contributions be set against pledges.


    protected
                    supportsRecurContributionsForPledges() : bool

In practice all processors that use the baseIPN function to finish transactions or call the completetransaction api support this by looking up previous contributions in the series and, if there is a prior contribution against a pledge, and the pledge is not complete, adding the new payment to the pledge.

However, only enabling for processors it has been tested against.

Return values

bool

supportsTestMode()

Are test payments supported.


    protected
                    supportsTestMode() : bool

Return values

bool

supportsUpdateSubscriptionBillingInfo()

Does this processor support updating billing info for recurring contributions through code.


    protected
                    supportsUpdateSubscriptionBillingInfo() : bool

If the processor returns true then it must be possible to update billing info from within CiviCRM that will be updated at the payment processor.

Return values

bool
