# Python SDK - 3.59.0

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:

* Added the `Psc` resource (`FirstName`, `LastName`, `Email`, `DateOfBirth`, `Country`, `Nationality`, `PscType`, `Status`, `ValidationDate`, `HostedUrl`, `Data`, `LastUpdate`) with `Psc.retry(identity_verification_id, psc_id)` for the PSC retry endpoint
* Added the `PSCs` (`pscs`) property on `IdentityVerification`

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

New hook event types: `IDENTITY_VERIFICATION_PSC_PENDING`, `IDENTITY_VERIFICATION_PSC_VALIDATED`, `IDENTITY_VERIFICATION_PSC_REJECTED`, `IDENTITY_VERIFICATION_PSC_ABANDONED`, `IDENTITY_VERIFICATION_PENDING_PSC_ACTION`, and `IDENTITY_VERIFICATION_EXPIRED`.

### Echo – GET List Intent external providers

Added `PayInIntent.get_external_providers_list()` for `GET /payins/intents/external-providers`.

### Echo – `Tag` on intent splits

`IntentSplit` now supports the `Tag` (`tag`) property.
