API to create or update a text2pay invoice
AI agents use text2pay-invoice 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 or updates a payment invoice in the GoHighLevel system. While it involves financial concepts (invoices), it doesn't directly move money or commit financial obligations — it creates/modifies an invoice record which is a Write operation. However, the severity is high because invoices can initiate payment flows and creating fraudulent or incorrect invoices could lead to financial harm 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 text2pay-invoice:
{
"version": "1",
"default": "deny",
"tools": {
"text2pay-invoice": {
"limits": [
{
"counter": "text2pay-invoice_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}text2pay-invoice 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.
