Questions

What can the AI do in SleekFlow?

It can read conversations, messages, contacts, contact lists, channels, staff, teams, labels, quick replies, broadcasts, WhatsApp templates and analytics. It can send messages and WhatsApp templates, assign conversations, add internal notes, create and update contacts and add or remove contacts from lists.

Does the AI see my SleekFlow API key?

No. Your SleekFlow API key is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start read-only. Sending a message or template reaches the customer right away, so it can require your approval before it runs. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own SleekFlow account. SleekFlow's Platform API needs a Premium or Enterprise plan.

Which API address should I choose?

SleekFlow runs a separate API address for each data region: Hong Kong, United States, Singapore, West Europe and UAE North. Pick the one where your SleekFlow account is hosted. The setup form lists the address for each region.
