      - name: filter
        in: query
        description: "Filter to apply, allowed fields are:\n- (String) `contact_id`\n- (String) `subscription_plan_id`\n- (String) `status`\n- (String) `id` - Allowable operators: \"==\", \"<=\", \"<\", \">=\", \">\", \"!=\"\n- (String) `billing_amount` - Allowable operators: \"==\", \"<=\", \"<\", \">=\", \">\", \"!=\"\n- (List[String]) `ids`\n- (List[String]) `subscription_plan_ids`\n\nCustom fields can be filtered by their field_name (case-insensitive, as returned\nby GET /v2/subscriptions/model). A standard field above takes precedence over a custom\nfield with the same name. The supported operators depend on the custom field's type:\n- Text-like fields (text, text area, name, email, phone, website, social security\n  number) and single-value choice fields with text options (dropdown, radio,\n  state): `==` only, with optional trailing wildcard (e.g. `_SubscriptionNote0%3D%3DValue%2A`)\n- Yes/No and drilldown fields: `==` only\n- Numeric fields (whole number, decimal, currency, percent, year, month, day of\n  week, user): `==`, `>`, `<`, `>=`, `<=`\n- Date fields: `==`, `>`, `<`, `>=`, `<=` using full ISO 8601\n- Multi-select fields: `==` matches records that contain the given option\nCustom field filtering on non-indexed fields is supported but may be slower.\n\nYou will need to apply the `==` operator (or other supported operators), to check the equality of one of the filters with your searched word, in the encoded form `%3D%3D`. For the filters listed above, here are some examples:\n- `filter=contact_id%3D%3D123`\n- `filter=subscription_plan_id%3D%3D456`\n- `filter=status%3D%3DActive`\n- `filter=id%3E5`\n- `filter=billing_amount%3E%3D100`\n- `filter=ids%3D%3D1,10,4,24`\n- `filter=subscription_plan_ids%3D%3D10,20,30`\n- `filter=contact_id%3D%3D123%3Bstatus%3D%3DActive`\n\nCustom field examples (for custom fields with field_name `_SubscriptionNote0` and `_SubscriptionCount1`):\n- `filter=_SubscriptionNote0%3D%3DTest` (custom field exact match)\n- `filter=_SubscriptionNote0%3D%3DTest%2A` (custom field prefix wildcard)\n- `filter=_SubscriptionCount1%3E100` (custom field numeric comparison)\n- `filter=contact_id%3D%3D123%3B_SubscriptionNote0%3D%3DActive` (combined standard + custom field filter)\n\nFor fields which allow wildcard matching, you may use the * wildcard character (or its encoded form %2A) for case-insensitive partial matching on text fields. Example of a valid pattern of wildcard usage:\n- `field==foo*` finds anything in `field` that begins with `foo`\n"
