CAPABILITY PROFILE
What the Gumroad integration exposes
The Gumroad Agent App exposes 9 provider-backed actions for finance and marketing work. Its current contract lets an authorized agent retrieve the authenticated gumroad user, refund a gumroad sale, optionally as a partial refund in cents, and mark a gumroad sale as shipped, optionally including a tracking url. These operations are called through Working Machines as typed capabilities rather than through browser navigation or copied UI steps.
A connection uses API key. 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 Gumroad account, granted provider permissions, workspace policy, region, plan, and upstream API behavior.

PROVIDER-SPECIFIC WORKFLOWS
Jobs this Agent App can support
Inspect Get Current User
Retrieve the authenticated Gumroad user. Use this as a bounded discovery step, retain the returned identifier, and avoid expanding the read beyond the task's stated scope.
get_current_userControl Refund Sale
Refund a Gumroad sale, optionally as a partial refund in cents. Resolve the target first, present material changes for confirmation, and make retries idempotent where the provider supports it.
refund_saleVerify with Get Product
Retrieve one Gumroad product by ID. Compare the returned provider state with the intended outcome and preserve stable IDs or canonical links in the run record.
get_productSAFETY BOUNDARY
Operate Gumroad with explicit limits
- Authorize Gumroad with API key and grant only the provider access required by the selected actions.
- 1 action is change-capable by name. Confirm the target identity and material parameters before allowing a write.
- Treat `refund_sale` 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 Gumroad rather than assuming unrestricted access.
- After a call, inspect the structured result and execution record before reporting that the Gumroad task completed successfully.
CONNECTION MODEL
API key
Gumroad access token passed as the access_token parameter. Generate it from the official Gumroad API page while signed in: https://gumroad.com/api.
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.

EVIDENCE AND AVAILABILITY
Provider reference
Action names, input fields, authentication types, and counts on this page are generated from the Working Machines provider catalog. Provider behavior, quotas, object semantics, account eligibility, and regional availability remain governed by Gumroad.
