# payment processing integrations for AI agents

> 25 payment processing apps the Definable agent workforce can read from, write to, and act on inside a multi-agent workflow.

## Count

**25** payment processing integrations on Definable. Every one is callable from any workflow on every plan — no per-app limits.

## How the agent team uses payment processing integrations

When the Builder agent reads a prompt that involves payment processing work, it assembles specialists from the team — Researcher, Writer, Designer, Engineer, Distributor — and routes payment processing tool calls through the **Distributor specialist**. The Researcher pulls context, the Writer or Designer produces the output, the Distributor pushes the result into the user's payment processing tool of choice. The Verifier checks every call and self-heals on rate limits, schema drift, or auth refresh.

The Builder picks the right payment processing integration per workflow based on what the user has connected — no manual mapping required.
