API to create an invoice Schedule
AI agents use create-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 creates an invoice schedule, which is a Write operation (creating new data). While it has financial implications (invoices), it does not directly move money or commit a financial transaction — it merely sets up a schedule for future invoices. The severity is medium because miscreating invoice schedules could lead to billing errors or unintended charges 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 create-invoice-schedule:
{
"version": "1",
"default": "deny",
"tools": {
"create-invoice-schedule": {
"limits": [
{
"counter": "create-invoice-schedule_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create-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.
