Filter Highlights

Exact Match

date: {
  exact: "2023-12-01"
}

• Matches one exact value
• Type must match schema
• Dates are strings in ISO format

---

Nested Filters

currency: {
  user_code: {
    exact: "CHF"
  }
}

• Filters on related objects
• Works through foreign keys
• Depth depends on schema rules

---

Common Filter Types

Typical filters you may see:

• exact
• in
• contains
• gte, lte
• isnull

Available filters depend on the field type.

---

Important Notes

• Filters are optional
• Multiple filters are combined with AND
• Wrong field names cause schema errors
• Always check the schema panel

This pattern applies to all list queries in Finmars GraphQL.
