    valid_until=None,
    consent_captured_at=None,
)

Create-or-update a SEPA payment mandate, keyed by (umr, creditor).

Capturing consent is one-way: once consent_captured_at is set on an existing mandate it is immutable, and status stays ENABLED. The only update permitted is granting consent on a previously PENDING mandate (consent goes None -> not-None, status flips PENDING -> ENABLED). Any other field divergence on update is silently ignored.

On create, status is ENABLED if consent_captured_at is set, else PENDING.

Parameters:

Name	Type	Description	Default
session	Session	Database session.	required
unique_key	str	Namespaced unique identifier {country}:{model}:{id}.	required
debtor_financial_instrument_id	FinancialInstrumentId	ID of the financial instrument to debit from.	required
creditor_legal_entity_id	LegalEntityId	ID of the legal entity authorized to collect.	required
payment_type	PaymentMandatePaymentType	Recurring vs one-off payment authorization.	required
umr	str	Unique Mandate Reference (max 35 chars, Latin only).	required
scheme	SepaPaymentMandateScheme	SEPA scheme (CORE or B2B).	required
valid_until	datetime | None	Mandate validity end date. Defaults to utcnow() + 36 months on create; ignored on update.	None
consent_captured_at	datetime | None	Timestamp of signature or explicit consent.	None

Returns:

Name	Type	Description
PaymentMandateId	PaymentMandateId	ID of the created or updated mandate.

Raises:

Type	Description
FinancialInstrumentNotFoundException	If the debtor FI does not exist (create only).
FinancialInstrumentTerminatedException	If the debtor FI is terminated (create only).
LegalEntityNotFoundException	If the creditor LE does not exist (create only).
LegalEntityTerminatedException	If the creditor LE is terminated (create only).
