[Variable API calls] [Workflow] Merges a source category into a target category: re-categorizes all transactions and moves all historical budgeted amounts. Dry run costs 4 + N calls (N = number of budget months). Execution costs additional 1 + 2*M calls (M = months with non-zero budgets). Defaults to dry_run=true to preview changes before executing. After merging, the source category will have zero transactions and zero budgeted amounts across all months - you can then manually hide/delete it in the YNAB app.

[Variable API calls] [Workflow] Audits credit card payment categories by comparing each card's month-end balance against the payment category's available balance. Recommends exact budgeted amount corrections, accounting for cascading effects across months. Audit costs 3 + C + M API calls (C = credit cards, M = months). Set apply=true to automatically fix mismatches (adds 1 API call per mismatch).

[0 API calls] Check current YNAB API usage against the 200 calls/hour rate limit. Use this before batch operations to ensure you have enough budget.
