• Boleto Charges — Generate boleto bancário payment slips.
• Charge Management — List, retrieve, and refund charges (full or partial).

Tools

Products (5 tools)

Tool	Description
list_products	List your seller's products with pagination and search. Each product carries the pixAutomatic flag
get_product	Get a single product by UUID — the identifier accepted by the charge tools. pixAutomatic enables Pix Automático on the public subscription checkout
get_product_portal_config	Read per-product portal customization (B2B2C). Returns null if unset — product falls back to seller-level config
set_product_portal_config	Upsert with merge: only fields provided are written. Pass null on a field to inherit from seller
clear_product_portal_config	Remove the per-product config; product falls back to seller-level config

Portal-config tools accept productId as either the product UUID (preferred — same id returned by list_products) or the legacy numeric id. UUID support added in Garu v0.10.0.

Use list_products to discover the UUID you'll pass to create_pix_charge or create_boleto_charge.

Per-product portal config is the B2B2C primitive: SaaS that models professionals/coaches/instructors as Products under one Seller can give each one custom branding (businessName, primaryColor, logoUrl) and policies on the customer payment page + /minha-area portal — all without fragmenting the seller's accounting.

Charges (5 tools)

Tool	Description
create_pix_charge	Create a PIX charge with QR code
create_boleto_charge	Create a boleto bancário charge
list_charges	List charges with pagination and filters
get_charge	Get charge details by ID (includes status)
refund_charge	Refund a charge (full or partial)

Customers (6 tools)

Tool	Description
create_customer	Create a customer linked to your seller account
list_customers	List customers with search and pagination
get_customer	Get customer details by ID
update_customer	Update customer information
delete_customer	Remove customer from your seller account
set_customer_billing_email_override	Override the billing-email used for that customer

Scheduled charges (13 tools)

Bill an existing customer on a future date — one-time or recurring with card tokenization or Pix Automático (BACEN auto-debit recurring Pix; recurring + productId only).

Tool	Description
create_scheduled_charge	Schedule a future charge. type='recurring' enables silent-charge of saved card on cycle 2+. methods accepts pix_automatic (Pix Automático — recurring + productId only). Optional maxRecoveryDays (1–365) caps how long past dueDate the recovery sweep keeps auto-billing a missed charge (default 14)
list_scheduled_charges	Paginated list with filters by status, type, due-date range, customer
get_scheduled_charge	Detail bundle: charge + event timeline + linked transactions
mark_paid_scheduled_charge	Mark a cycle paid (off-Garu reconciliation)
charge_now_scheduled_charge	Force-bill the current cycle now instead of waiting for the due date (same dispatch as the daily cron). Idempotent — reports already_sent rather than re-charging
postpone_scheduled_charge	Move next due date forward
pause_scheduled_charge / resume_scheduled_charge	Suspend / re-enable a series
cancel_recurrence_scheduled_charge	Hard-stop future cycles (recurring only)
cancel_at_period_end_scheduled_charge	Stripe-style soft-cancel; reversible
change_scheduled_charge_payment_method	Swap the saved card
clear_scheduled_charge_payment_method	Remove saved card; future cycles email-with-link
list_scheduled_charge_attempts	Per-attempt billing log (v0.8.2). Each row carries the canonical failureCode for declines — use this to debug recurring billing failures without joining Transactions
