Automate PayPal with a workflow

A workflow runs your methods as one process, with nobody at the screen. A schedule or a call from your own system starts it, the steps run in order, and the result arrives in your inbox or in the systems you already use.

• New cases that need your attention, every morning

  Build this

  Starts

  Every weekday at 8:00

  Step 1

  List the cases on the Needs your attention tab of the Resolution Center.

  Step 2

  Keep the cases that were not there on the last run.

  Step 3

  Email you each new case with its Case ID, transaction ID, date reported and status.

• Yesterday's transactions, handed to accounting

  Build this

  Starts

  Every day at 6:00

  Step 1

  Get the account activity for yesterday from the Activity Download report.

  Step 2

  Stop when there are no transactions.

  Step 3

  Post each transaction's date, name, type, status, gross, fee, net and transaction ID to your accounting webhook.

• Monthly statement totals for the month-end close

  Build this

  Starts

  Monthly on the 3rd at 9:00

  Step 1

  Get the monthly statement summary for last month.

  Step 2

  Post its balance summary and activity summary by category to your accounting webhook.

You can run a workflow by hand on every plan, Free included. Schedules and webhook triggers come with the paid plans, from $29 a month.

Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get account activity for a date range” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "www.paypal.com/get_account_activity",
    "input": {
      "start_date": "2026-11-10",
      "end_date": "2026-11-10"
    }
  }'

{
  "status": "completed",
  "data": {
    "transactions": [
      {
        "date": "2026-11-10",
        "time": "09:14:52",
        "name": "Northwind Traders",
        "type": "Express Checkout Payment",
        "status": "Completed",
        "currency": "USD",
        "gross": 240,
        "fee": -8.87,
        "net": 231.13,
        "transaction_id": "7XK20419LM558310A",
        "reference_transaction_id": "",
        "invoice_number": "ACME-2291"
      }
    ],
    "count": 1
  }
}

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

PayPal’s own options

PayPal offers REST APIs for developers: Transaction Search lists transactions and balances for the previous three years, and the Disputes API lists disputes and takes the Resolution Center's actions. Settlement and other reports come by SFTP once PayPal support enables your account. Monthly and custom statements and the Activity Download report are generated in the reporting portal.

Signing in to PayPal

You sign in to your PayPal business account on paypal.com, and the Resolution Center and the reporting portal are part of that account. With Fous you sign in once through PayPal's own sign-in with your own account: the login is sealed with AES-256, never returned by the API or written to logs, and code and AI agents never see it.

Worth knowing

Statements come after the 2nd of the month

A monthly statement can be requested any time after the 2nd. The portal keeps up to 2 years of monthly statements and 12 custom statements, and a custom statement can need a Refresh after about 2 minutes.

Statements leave out pending items

Statements include only transactions that affect your PayPal balance, so uncaptured authorizations, pending eChecks and unresolved disputes are not in them. A PDF with more than 10,000 transactions lists none.

Activity Download covers 12 months at a time

You can pick any period within the last 7 years, up to 12 months per report. CSV and TAB files stop at 50,000 records, and a larger report arrives as several files in a ZIP.

Escalating a case ends the conversation

After you select Escalate issue to PayPal, you can no longer message the buyer, and PayPal holds any earlier offers or refunds while it reviews the case.
