Vista API Enhancements — Since July 21, 2026

This release period adds Project Management cache coverage, AP payment-batch grouping enhancements, new PM and Payroll actions, VA inquiry refresh, and multiple high-impact fixes across AP, SM, PO, MS, PR, and DM modules.

Data object and action descriptions were updated across Vista modules to include missing native Vista program and view references (CM, GL, HR, JC, PR, PM, SM, VA, UD, and others) as well as in App Xchange description updates to supplement the file handling documentation.

Data and Cache Improvements

VA Inquiry Refresh

Added refresh_inquiry on inquiry data so integrators can re-run a VA inquiry with change detection instead of recreating inquiry runs on every schedule. Supports optional filter override and standard delete-detection behavior.

Project Management Paperless Caches

Added cache writer support for PM daily logs, inspection logs, drawing logs, issues, meeting minutes, and request for information (RFI) data objects to support construction document and field-log integrations.

Equipment Management Assets

Added a new Assets cache data object for EM asset header and depreciation schedule data (vista/em/2/data/assets/cache).

Job Cost

Added Contracts Forecast cache writer support.

Service Management

Added Work Order Scopes cache writer support. Reverted an earlier work order scope schema change that had caused cache compatibility issues.

Document Management Attachments

When a separate attachment database is configured but HQAF bytes exist only in the primary Viewpoint database, attachment_files/cache_file now falls back to the primary database before failing — fixing legacy attachment retrieval scenarios.

API Improvements

Module	Change Type	Data Object	Description
AP	Enhanced	Pay Batch Entries Add Action	Repeated Add calls for the same vendor in the same payment batch now group onto one payment header when `SeparatePayYN` is `N` and vendor, pay method, CM account, and address sequence match.
AP	Enhanced	Pay Batch Entries Add Action	Added optional grouped input via `LineItems[]` to add multiple open AP transactions for one vendor in a single API call.
AP	Fixed	Pay Batch Entries Add Action	Fixed intermittent incorrect vendor assignment when adding open invoices to a payment batch.
PM	Added	Firms	Added the Add action for PM Firms to allow programmatically creating firm master records.
PR	Added	Crews	Added the Add action for Payroll Crews to allow programmatically creating crew records.
SM	Enhanced	Work Orders Add Action	Work Orders Add now automatically creates default Scope 1, matching Vista UI behavior so work-completed lines can post without an explicit scopes payload.
VA	Added	Inquiry Data	Added refresh_inquiry action to re-execute VA inquiries with incremental change detection.
VA	Fixed	Clear Inquiry Action	Fixed Clear Inquiry returning HTTP 400 when clearing a valid inquiry run.
MS	Fixed	Ticket Batch Entries Add Action	Fixed null reference failures on `ticket_batch_entries/add`.
PO	Fixed	CO Batch Entries Add Action	Fixed null reference failures when optional/null fields are sent on `co_batch_entries/add`; improved input validation.
SM	Fixed	WO Work Completeds Add Inventory Action	Fixed `add_inventory` failures when the same Part code exists in multiple material groups by scoping HQMT lookup to the company material group.
PR	Fixed	Time Batch Entries Add Action	Fixed pay rate defaulting when Vista returns a null craft template — seq 127 is now explicitly cleared so a prior line's template does not carry forward.
DM	Fixed	Attachment Files Cache File Action	Fixed unexpected errors when staging attachment bytes for download.
