CAPABILITY PROFILE
What the PayPal integration exposes
The PayPal Agent App exposes 14 provider-backed actions for finance work. Its current contract lets an authorized agent retrieve details for a paypal authorized payment, add shipment tracking information to a completed capture in a paypal order, and retrieve the current details and status of a paypal refund. These operations are called through Working Machines as typed capabilities rather than through browser navigation or copied UI steps.
A connection uses Custom credentials. Before execution, the agent can inspect the selected action, its required fields, declared scopes, and expected output contract. Provider credentials remain inside the Working Machines runtime; the calling agent receives the capability and its structured result, not the underlying secret.
For reliable operation, start with the narrowest action that satisfies the task, resolve stable provider identifiers before changing state, and validate the returned object or status after execution. Availability still depends on the connected PayPal account, granted provider permissions, workspace policy, region, plan, and upstream API behavior.

PROVIDER-SPECIFIC WORKFLOWS
Jobs this Agent App can support
Inspect Get Authorization
Retrieve details for a PayPal authorized payment. Use this as a bounded discovery step, retain the returned identifier, and avoid expanding the read beyond the task's stated scope.
get_authorizationControl Add Tracking
Add shipment tracking information to a completed capture in a PayPal order. Resolve the target first, present material changes for confirmation, and make retries idempotent where the provider supports it.
add_trackingVerify with Get Balances
Retrieve PayPal account balances, including available and withheld amounts by currency. Compare the returned provider state with the intended outcome and preserve stable IDs or canonical links in the run record.
get_balancesSAFETY BOUNDARY
Operate PayPal with explicit limits
- Authorize PayPal with Custom credentials and grant only the provider access required by the selected actions.
- 5 actions are change-capable by name. Confirm the target identity and material parameters before allowing a write.
- Treat `get_refund` and `refund_capture` as high-impact operations and require an explicit approval boundary.
- No provider scope string is declared on the sampled actions. Verify the connected account's actual permissions in PayPal rather than assuming unrestricted access.
- After a call, inspect the structured result and execution record before reporting that the PayPal task completed successfully.
CONNECTION MODEL
Custom credentials
PayPal uses Custom credentials. Connection requirements and availability are determined by the provider and the Working Machines deployment.
Working Machines stores provider credentials behind the execution boundary. An agent can use an authorized connection identity, but catalog discovery alone does not reveal OAuth tokens, API keys, or provider secrets.
