# INSTALLMENT\_FILTERS

**Type**: `array` of filter objects\
**Default**: `[]` (empty array)\
**Validator**: `InstallmentFiltersSerializer`\
**Description**: Filters that restrict which installment options are available to users.

Each filter object has the following structure:

* `klass`: Filter class path (string from `InstallmentFilterType` enum, required)
* `kwargs`: Filter parameters (dictionary, required)

**Filter evaluation**:

* Applied sequentially in array order during `InstallmentService.filter_installments()`
* Each filter receives the basket, installments list, and additional context (currency, user\_email)
* Filters can remove installment options based on their criteria
* If a filter returns `final=true`, no further filters are processed
* Messages from filters are collected and returned to inform the user

**Used in**: `InstallmentSelectionPage`, `BexInstallmentSelectionPage` via `InstallmentService.get_pre_order_installments()` to filter available installments
