SAP Concur will release the Budget v4 API for partner and client use in a future release. Budget v4 provides the following features:
This new Budget API enables clients and partners to integrate Budget with their ERP and HR systems to automate budget configuration and maintenance as well as importing external transactions not captured via SAP Concur through budget adjustments.
The Budget v4 API will be available to SAP Concur clients who have purchased Web Services, or partners who have contracted with SAP Concur.
SAP Concur is releasing the Quick Expense v4 API for payment partner use.
This new version of the Quick Expense API supports the latest SAP Concur API authentication method, and provides several enhancements to the POST functionality.
SAP Concur is deprecating the Quick Expense v3 API due to security vulnerabilities identified. This API is being replaced by Quick Expense v4. Quick Expense v3 will be decommissioned in a future release. Please migrate to the Quick Expense v4 API.
The Quick Expense v3 API only supports the previous authentication method, and it provides access to some fields that are not necessary to expose. These issues are resolved with the new Quick Expense v4 API.
