​
Overview

The Update Expense Category endpoint allows you to modify existing custom expense categories. You can update the name, parent category, and visibility settings. Important Limitations:
  • You can only update custom categories that you created
  • System default categories cannot be modified via the API
  • Categories that belong to your firm only

​
Path Parameters

​
id
integer
required
The unique identifier of the expense category to update

​
Request Body

All parameters are optional - only include the fields you want to update.
​
name
string
The new name for the expense category
​
parent_id
integer
New parent category ID. Use 0 to make it a root-level category, or specify an existing category ID to move it under that parent.
​
is_visible
boolean
Whether the category should be visible and available for use when creating expenses

​
Validation Rules

  • Name: Must be non-empty if provided
  • Parent Category: Must exist and belong to your firm (if specified)
  • Hierarchy: Cannot create circular references or exceed 2-level depth
  • Self-Reference: A category cannot be its own parent
  • System Categories: Cannot update categories with type: "system"

​
Hierarchy Constraints

  • Maximum Depth: Categories can only be 2 levels deep (category → subcategory)
  • Parent Validation: Parent must be a root-level category (parent_id = 0)
  • Circular Reference: Prevents categories from referencing themselves or creating loops
