What you get

ChatGPT asks Pink before it pays

Once connected, ChatGPT can see its budget, the payees it may pay and the rules that apply, run a dry run, request a payment and file the receipt. The rules you set in Pink decide each request: allowed on the spot, sent to a person on the phone, or blocked. ChatGPT never holds a card number or a bank login.

Step by step

  1. 1

    Create a free sandbox workspace

    Open agentic-sandbox.pinkwallet.com, type a company name, pick a template (coffee shop, startup or e-commerce) and click Create workspace. You get an admin key for the console and one key per AI agent. Keep the admin key: the sign-in page asks for it.
    After creating a workspace: the admin key and one key per agent are shown once

    Turn on Developer mode

    In ChatGPT open Settings → Connectors, scroll to Advanced settings and switch on Developer mode. Without it ChatGPT only accepts search-style connectors and will not show Pink's payment tools.
  3. 3

    Create the connector

    Still under Connectors, click Create. Name it Pink, paste https://agentic-sandbox.pinkwallet.com/mcp as the MCP server URL, choose OAuth as the authentication and click Create. ChatGPT discovers Pink's sign-in automatically.
  4. 4

    Sign in on Pink's page and pick the agent

    ChatGPT opens Pink's sign-in page. Paste your admin key, choose which agent ChatGPT should act as (for example Purchasing AI), then click Allow. From now on ChatGPT holds a token for that one agent, never a card number or a bank login.

    Enable it in a chat

    In a new chat click + (or the tools menu), pick Pink under connectors, and ask ChatGPT to buy something. It shows each tool call and Pink's answer.
  6. 6

    Watch the approval land in the console

    Open the sandbox console (link on the workspace page). Requests that cleared, asked a person or were blocked are all listed with the rule that decided them. Approve the pending one and the agent continues.

Try it: say this to ChatGPT

Say this

“Check my budget with Pink, then order 20 kg of espresso beans from Counter Culture Coffee for $420. After that, order $890 of weekly supplies from Sysco.”

What you will see

The first order is allowed on the spot and the agent receives a single-use test credential. The second stops at the store manager's rule ($500–$2,000): it shows up under Approvals in the console, and the agent waits for a person. Approve it there and the agent picks up the credential.

FAQ

Why does ChatGPT need Developer mode?

Standard connectors in ChatGPT are built for search and fetch. Developer mode is OpenAI's switch for full MCP tool use, including write actions such as requesting a payment.

Is it available on the free plan?

No. Developer mode and custom connectors need Plus, Pro, Business, Enterprise or Edu.

Can an admin add Pink for the whole workspace?

On Business and Enterprise an admin can publish the connector so members only have to sign in.
