Release highlights
The 2026.05 release of ONESOURCE Indirect Tax Configuration APIs introduces new endpoints for currency rules and currency specifications, extends the existing Rules endpoints with global rule support, and adds total count reporting across GET list APIs, enabling more complete and automated tax jurisdiction configuration workflows.

New features
GET List APIs - Total Count Support (5488146, 5488144, 5351490, 5488136, 5488155, 5488153)
All GET List APIs across the Configuration API suite now support a new totalCount query parameter. When totalCount=true, the response includes the total number of available records under meta.totalCount, giving users visibility into full result-set size without impacting pagination behavior. When totalCount is false or omitted, the total count is not calculated.
GET Currency Rules (5176027)
A new web service endpoint is available to retrieve currency rules configured for a company, including rounding rules, rounding precision, and minimum accountable unit definitions. This allows users to review existing currency configurations, supporting validation before configuring currency specifications or authority currency overrides.
POST Currency Rules (5176028)
A new web service endpoint is available to create currency rules for a company in a single batch request, up to 50 records per request. This enables users to programmatically configure currency rounding and precision settings at scale, supporting all-or-nothing batch validation so that the entire request is rejected if any record fails.
PATCH Currency Rules (5176029)
A new web service endpoint is available to update existing currency rules for a company. This allows users to keep rounding rules, precision settings, and minimum accountable unit definitions current, ensuring currency configurations remain accurate as business requirements or regulatory standards evolve.
DELETE Currency Rules (5176030)
A new web service endpoint is available to delete a currency rule for a company. This enables users to permanently remove currency configurations that are no longer applicable, keeping the company's currency rule list accurate and up to date.
GET Currency Specifications (5242762)
A new web service endpoint is available to retrieve currency specifications for a company, including rounding rules, precision settings, minimum accountable units, and associated exchange rate sources. This allows users to review and validate currency configuration details, supporting subsequent tax calculation and currency management workflows.
POST Currency Specifications (5242763)
A new web service endpoint is available to create currency specifications for a company. This enables users to programmatically configure currency rounding rules, precision settings, minimum accountable units, and exchange rate source associations, supporting accurate tax calculation and currency management.
PATCH Currency Specifications (5242765)
A new web service endpoint is available to update existing currency specifications for a company. This allows users to maintain accurate rounding rules, precision settings, effective dates, and exchange rate source associations, ensuring configurations stay current as requirements change.
DELETE Currency Specifications (5242766)
A new web service endpoint is available to delete a currency specification for a company. This enables users to remove unused or invalid currency configuration records from the system, and the response returns the id of the deleted record to confirm the operation.
GET Rules (5591376)
The GET Rules endpoint now supports an optional isCustomGlobalRule query parameter, allowing users to retrieve standard custom rules or custom global rules through the same endpoint using the same response schema.
GET Rule Details (5591377)
The GET Rule Details endpoint now supports an optional isCustomGlobalRule query parameter, allowing users to retrieve a specific custom rule or custom global rule by ID through the same endpoint.
POST Rules (5591378)
The POST Rules endpoint now supports an optional isCustomGlobalRule query parameter, allowing users to create a custom rule or a custom global rule using the same request body and endpoint.
PATCH Rules (5591379)
The PATCH Rules endpoint now supports an optional isCustomGlobalRule query parameter, allowing users to update a custom rule or a custom global rule using the same request body and endpoint.
DELETE Rules (5591380)
The DELETE Rules endpoint now supports an optional isCustomGlobalRule query parameter, allowing users to delete a custom rule or a custom global rule using the same endpoint.
Fixes
Same Start/End Date Validation Restriction (5476875, 5565799, 5565794)
An issue was reported where several Configuration API endpoints rejected requests where the start/effective date and end/expiration date were the same, even though the UI supported this scenario. This issue has been resolved, and affected endpoints now accept a matching start and end date.
POST Exchange Rates Validation Performance (5505944)
The POST Exchange Rates endpoint has been optimized to reduce unnecessary iteration when validating incoming exchange rates against existing records. This improves response times for high-volume submissions, with no change to existing validation behavior.
Known issues
Operating Licenses APIs – Response Performance
An issue has been identified across all Operating Licenses API operations, where response times are higher than expected under certain conditions. This will be addressed in an upcoming release.
