API to update scheduled recurring invoice
AI agents use update-and-schedule-invoice-schedule to create or update resources in GoHighLevel MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GoHighLevel MCP Server environment.
This tool modifies invoice scheduling data, which is a write operation affecting financial records. While it doesn't move money directly (which would be Financial category), it alters the timing and terms of recurring billing obligations. The high severity reflects the blast radius: misconfiguring invoice schedules could cause billing errors, missed payments, or customer overcharges.
From the tool's definition Tool name explicitly states 'update-and-schedule-invoice-schedule' and description confirms it 'update[s] scheduled recurring invoice' — this is a modification operation on financial records.
