Everything the console does to links, campaigns, rules and reports, a program can do too. There are two ways in, and they open onto the same rooms: the same rules apply, the same refusals come back in the same words, and every change is recorded in the activity log with the token that made it.

​
The API

A REST API at https://app.utmkit.co/api/v1. Use it from a script, a backend, a spreadsheet integration, or anything that can send an HTTP request. Every request carries a token you mint on the console’s tokens page; the token decides which workspace the request acts on, so no request ever names one. Start with Authentication & tokens, then the reference in the sidebar: one page per operation, generated from the API’s own contract, with a playground to try a call from the browser.

​
The MCP server

An MCP (Model Context Protocol) server at https://app.utmkit.co/mcp. Point Claude Desktop, Claude Code, Cursor or any MCP client at it with the same kind of token, and your assistant can list, create, edit and withdraw links, manage campaigns and rules, and read the report, in your own words. Every tool maps to one token permission; a tool your token lacks is not even shown. The MCP server page has the connection steps, and it explains the one thing that trips people up: this site has an MCP server of its own, which only searches these pages.

​
Which one, when

  • A script or a backend that creates links in bulk, syncs campaigns, or pulls the report into a dashboard: the API.
  • A person working through an assistant, asking for “a link for the spring newsletter, source newsletter, medium email”: the MCP server.
  • Your own server reporting a sale or a sign-up against a link: the API, and only the API. A conversion is your server’s event, not a person’s, so it has no console form and no MCP tool. See Conversions.

​
What both share

  • The token’s permissions, chosen when you mint it, and your role in the workspace, checked live on every call.
  • The workspace’s rules: a link that the convention, the approved values or the dependency rules would refuse in the console is refused here too, with the same sentence.
  • The rate limit, per token, described in Rate limits.
  • The error shape, described in Errors.

For assistants reading this site

This documentation is also published for machines. The page index is at https://docs.utmkit.co/llms.txt, and every page has a plain-text twin: add .md to its address. The MCP server at https://docs.utmkit.co/mcp searches these pages and nothing else; it does not touch your workspace. To operate a workspace, use the product’s server described on the MCP server page.
