# Query for historic variable instances

`POST /cmmn-query/historic-variable-instances`

## Request

- Base URL: `https://developer-docs.flowable.com/cmmn-api`
- URL: `https://developer-docs.flowable.com/cmmn-api/cmmn-query/historic-variable-instances`
- Auth: HTTP basic
- TypeScript: <https://skmtc.dev/flowable/apis/flowable-cmmn-rest-api/docs/cmmn-query/historic-variable-instances/post.ts> (a function with typed inputs; its response is checked against the schema)

All supported JSON parameter fields allowed are exactly the same as the parameters found for getting a collection of historic process instances, but passed in as JSON-body arguments rather than URL-parameters to allow for more advanced querying and preventing errors with request-uri’s that are too long. On top of that, the query allows for filtering based on process variables. The variables property is a JSON-array containing objects with the format as described here.

## Query parameters

- `sort` 'caseInstanceId' | 'variableName'
