Integration
Connect Langfuse and Userflow
When New Trace fires in Langfuse, your agent runs Create/Update User in Userflow, or Checklist Completed in Userflow to Add Comment in Langfuse. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.
What do you want Langfuse and Userflow to do together?
Ask the assistant
Connect your AI client
Give your AI client this address.
https://mcp.apiant.aiOne connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.
Set it up in your client
Claude Code
Run this in the directory you want to work in.
claude mcp add --transport http -s project apiant-ai https://mcp.apiant.aiStart Claude Code there, approve the server, and sign in in the browser page it opens.
Claude Code guide (opens in a new tab)Claude, web and desktop
Open Customize, then Connectors, then Add custom connector, and paste the address. On Team and Enterprise an owner adds it first.
Setup guide (opens in a new tab)Cursor
Add the address to your MCP configuration as a server URL. Cursor signs you in in your browser.
Setup guide (opens in a new tab)Zed
Open Settings, then AI, then MCP Servers, then Add Server, then Add Remote Server.
Setup guide (opens in a new tab)Codex and the ChatGPT desktop app
Open Settings, then MCP servers, then Add server, and choose Streamable HTTP. From the terminal, Codex takes the address with its own add command and then signs you in.
Setup guide (opens in a new tab)Any other MCP client
Paste the address where the client asks for a remote MCP server URL, and name the server apiant-ai where it lets you. APIANT's skills reach the client over the same connection.

- Checklist Task Completed
Triggered when a user completes a single task inside a Userflow checklist.
- Event Tracked

- Flow Completed
Triggered when a user completes a Userflow flow by reaching its goal step.
- Flow Dismissed/Ended
Triggered when a Userflow flow ends for a user — because they dismissed it, finished it, or it stopped applying. The reason is in flow_end_reason.

- User Created/Updated
Triggered when a user is created or changed in Userflow.
- Create/Update Group
Creates a group (a company or account) in Userflow, or updates it if a group with that ID already exists. Only the attributes you send are changed.
- Create/Update User
Creates a user in Userflow, or updates them if a user with that ID already exists. Only the attributes you send are changed. Optionally adds the user to a group.
- Find Group
Finds groups (companies or accounts) in Userflow by name. Userflow's API cannot filter on the server, so this reads up to 300 groups and matches them here; leave the name blank to just list them.
- Find User
Finds users in Userflow by email or name. Userflow's API cannot filter on the server, so this reads up to 300 users and matches them here; leave both fields blank to just list them.
- Track Event
Tracks an event for a user in Userflow, so you can use it to start flows or checklists and to segment users.
No trigger or action matches that. Ask your agent to add it: it reads the API documentation and builds what you describe.

Questions
Langfuse and Userflow, answered
What can start an automation from Langfuse?
Any of Langfuse's 1 trigger in the catalog, including New Trace. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Userflow when something happens in Langfuse?
Any of Userflow's 5 actions, including Create/Update Group, Create/Update User, Find Group and Find User. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Userflow to Langfuse?
Yes. When something happens in Userflow, your agent can act in Langfuse too. This page covers both directions: Userflow's triggers and Langfuse's actions are listed here as well.
Do I have to build a connector for Langfuse or Userflow?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use Langfuse and Userflow without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
