Input Validators

Validators are added to individual input mappings in a query. Input validation allows data services to validate the input parameters in a request and stop the execution of the request if the input doesn’t meet the required criteria. WSO2 Micro Integrator provides a set of built-in validators for some of the most common use cases. It also provides an extension mechanism to write custom validators.

Long Range validator

Validates if an integer value is in the specified range. The validator requires a minimum and a maximum value to set the range.

Double Range validator

Validates if a floating point is in the specified range. The validator requires a minimum and a maximum value to set the range.

Length validator

Validates the string length of a given parameter against a specified length.

Pattern validator

Validates the string value of the parameter against a given regular expression.
