API to schedule an schedule invoice to start sending to the customer
AI agents use 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 schedules an invoice for delivery, which creates or modifies a scheduled billing record. It does not immediately move money but commits to future financial communication. Since it is scheduling rather than executing a payment, Write is the most appropriate category; however, it has financial implications as it triggers invoice delivery to customers.

PolicyLayer is an MCP gateway — it sits between your AI agents and GoHighLevel MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for schedule-invoice-schedule:
{
"version": "1",
"default": "deny",
"tools": {
"schedule-invoice-schedule": {
"limits": [
{
"counter": "schedule-invoice-schedule_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}schedule-invoice-schedule stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
