Update an existing invoice template
AI agents use update_invoice_template 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 template configurations, which affects how invoices are generated and presented to customers. While not directly moving money, invoice templates are closely tied to billing and financial operations. However, the operation is reversible (templates can be re-updated or restored), and the tool itself does not process payments or commit financial obligations.
From the tool's definition Tool name is 'update_invoice_template' with description 'Update an existing invoice template'. The verb 'update' indicates modification of existing data (an invoice template). This is a write operation that creates or modifies data reversibly.

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 update_invoice_template:
{
"version": "1",
"default": "deny",
"tools": {
"update_invoice_template": {
"limits": [
{
"counter": "update_invoice_template_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_invoice_template 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.
