[**Create a new export job**](/reference/export-api/export-api-v3/create-a-new-export-job) now accepts an optional `targetSystem` field, validated against the company's active connections; supplying an unrecognised value returns a `422` with an `INVALID_TARGET_SYSTEM` error

For more information, see [Chart of Accounts API Overview](/reference/chart-of-accounts-api-overview). ## Export API Version 3 A new version is released to support multi-currency configuration. For more information, see [Multi-Currency Configuration](/reference/multi-currency-configuration). The significant changes introduced in this version are:

In the endpoints' response, values of enums are now returned as strings.

`GET Get Export Items` endpoint:

`controlAccount` object is returned in the endpoint response.

`teamCode` is removed from the endpoint response.

`GET Get a list of Export Jobs` endpoint:

`status` is removed from the query parameters of the endpoint request.

`statuses` is the query parameter to request jobs in specific states.

## Webhook Subscriptions | Basic and Header-Based Authentication We now support **Basic** and **Header-Based** authentication methods, in addition to **HMAC signature-based** authentication. For more detailed information, see [Authentication in Webhooks](/reference/overview-webhooks#authentication-in-webhooks). Also, now an integration can send custom headers in a new subscription request — see [Configuring Custom Headers in New Subscription Request](/reference/overview-webhooks#configuring-custom-headers-in-new-subscription-request). ## Export API Version 2 You can now tag vendors to an expense, if the specific company has synchronised vendors between their ERP/accounting system and Pleo. Also, the integration must support vendor tagging. For more information on vendor specific data points that you might receive in an API response, see [POST Get Export Items](/reference/export-api/export-items-v2/get-export-items) \`. ## Accounts API Version 1 The Accounts API is now available for synchronisation of accounts between the ERP/accounting system and Pleo. For more information, see [Accounts API](/reference/chart-of-accounts-api-overview). ## Vendors API Version 1 The Vendors API is now available for synchronisation of vendors records between the ERP/accounting system and Pleo.

In addition, you can search for employee details of an organisation or company by `companyId`, `email`, or `code` in Version 2. For more information, see [Employees API Overview](/reference/employees-api-overview). ## Export API Version 2 V1 is operational, but we recommend you to upgrade to V2 for better user experience - the user attribute in `GET Get Export Items` response would be null, if there is no user/employee associated with the export item. For more information, see [Export API](/reference/export-api-overview). Also, V0 would be deprecated in 2025. Closer to the deprecation date, we would inform you.
