Agent Ready helps Braintree merchants accept payments from AI shopping assistants across major platforms, including ChatGPT, Google AI Mode, and Gemini, without building separate integrations for each. PayPal supports two agentic commerce protocols:
ProtocolAI platformIntegration path
Agentic Commerce Protocol (ACP)ChatGPT, OpenAIDelegated payment tokens through Braintree
Universal Commerce Protocol (UCP)Google AI Mode, GeminiGoogle Pay payment handler through Braintree

How it works

When a customer shops through an AI assistant, the assistant handles product discovery and checkout orchestration. Agent Ready connects your Braintree integration to these AI surfaces so you can:
  • Accept payments initiated by AI agents on behalf of customers.
  • Leverage your existing Braintree merchant account and processing relationship.

Choose your integration

Enable instant checkout in ChatGPT Apps using delegated payment tokens through Braintree.

Universal Commerce Protocol integration

Enable the Buy button in Google AI Mode and Gemini using the Google Pay payment handler through Braintree.
The key difference between these integrations is the AI platform they support and how payment credentials are obtained and processed.
