# PHP SDK - 4.4.0

August 18, 2026

## Added

### Support for multi-session PSC flow on hosted KYB for Business

To support verification of multiple PSCs on hosted KYC/KYB for Business-type users, new `Psc` entity (`FirstName`, `LastName`, `Email`, `DateOfBirth`, `Country`, `Nationality`, `PscType`, `Status`, `ValidationDate`, `HostedUrl`, `Data`, `LastUpdate`) and new `PscData` DTO (`Type`, `Value`). `IdentityVerification` gained a `PSCs` property (`Psc[]`) with the matching `GetSubObjects()` mapping.

New method `ApiIdentityVerification::RetryPsc($identityVerificationId, $pscId, $psc = null)` (`PUT /identity-verifications/{IdentityVerificationId}/pscs/{PscId}/retry`) to request the retry of a PSC session. The `$psc` argument is optional and may carry the values to update.

See the [multi-session PSC flow guide](/guides/users/verification/hosted/business) and the [API release note](/release-notes/api/2026-08-18) for more details.

### Identity verification event types

`EventType` gained `IDENTITY_VERIFICATION_PSC_PENDING`, `IDENTITY_VERIFICATION_PSC_VALIDATED`, `IDENTITY_VERIFICATION_PSC_FAILED`, `IDENTITY_VERIFICATION_PSC_ABANDONED`, `IDENTITY_VERIFICATION_PENDING_PSC_ACTION`, and `IDENTITY_VERIFICATION_EXPIRED`.

### Echo – GET List Intent external providers

New method `ApiPayIns::GetExternalProvidersList()` (`GET /payins/intents/external-providers`) returning the list of external payment provider names.

## Changed

### Echo – `Tag` on intents and splits

Test coverage added for the `Tag` property on intent authorizations, captures, refunds, and splits; no API change.
