• create_discount_codes Create one discount code, or up to 100 with a prefix. writeasks first

  Fills the Add a new code form in Communicate > Discount Codes. Codes apply per ticket, not per order, and not to tickets issued as part of a donation. Each code stops working when its uses are spent. It returns the codes created. A code lowers what buyers pay, so it waits for your OK. Undo it with set_discount_code_active. By default you confirm each call; you can switch that off for this tool.

    ]
  }

• set_discount_code_active Activate or deactivate a discount code. writeasks first

  Does what the green symbol next to a code does. A deactivated code stays in the list and keeps its settings, so one call with active true brings it back. Switching a code on gives buyers a discount again. By default you confirm each call; you can switch that off for this tool.

• request_refund Ask Weezevent to refund the buyer's card for an online order. writeasks first

  Does Actions > Refund Request on the order. It works for online orders only. Weezevent's commission is still owed, plus a re-crediting fee of 2 EUR excluding VAT per refunded order. The buyer usually sees the money in 1 to 3 business days after those invoices are paid. Track it with list_orders and refund_requested true. By default you confirm each call; you can switch that off for this tool.
