An expression set is a user-defined rule that accepts an input and returns the output based on the configured function.\n\nThe configured function of an expression set can be a simple decision matrix lookup, a calculation based on a mathematical formula, a condition, or another expression set.\n\nThese actions are available in API version 55.0 and later.\n\n## Supported REST HTTP Methods\n\nURI/services/data/v55.0/actions/custom/runExpressionSet/{ApiName}\n\n> `Note` \n \n> `The API name of an expression set is unique within your Salesforce instance.` \n \n\nFormats\n\nJSON\n\nHTTP Methods\n\nPOST\n\nAuthentication\n\nAuthorization: Bearer token\n\n## Inputs\n\nVary depending on the selected expression set.\n\n## Outputs\n\nVary depending on the inputs of the selected expression set.\n\n## Usage\n\nThis section has the sample request and response for invoking an expression set that does the following:\n\n1. Find the tax percentage and the premium corresponding to specific age and salary using a decision matrix lookup.\n \n2. Check the age criterion to calculate the total tax.\n \n3. Calculate the total tax to be paid based on the age group, salary, and the tax percentage.\n \n\nSample request\n\nHere’s an example POST request that has the inputs, such as, age and salary:\n\n```\n{\n \"inputs\":[\n {\n \"Age\":\"25.00\",\n \"Salary\":\"50000.00\"\n }\n ]\n}\n\n ```\n\nSample response\n\nHere’s an example response that has the premium and tax values based on the inputs provided in the example request:\n\n```\n[\n {\n \"actionName\":\"TaxPremiumES\",\n \"errors\":null,\n \"isSuccess\":true,\n \"outputValues\":{\n \"TaxPremium__Premium\":1000,\n \"TaxPremium__Tax\":10,\n \"TaxToBePaid\":1050,\n \"condition_output__2\":\"false\",\n \"condition_output__1\":\"true\"\n }\n }\n]\n\n ```"
