Onboarding Flow

• Custom credentials can be configured through synchronously providing credential schemas in Fetch Store Credentials (stores.fetch_credentials) webhook.
• When custom credentials are configured, their values will be present in the Upsert store (stores.upsert) webhook.
• When a store is added on Public API internal services, the stores.upsert webhook is called and partner must return 2XX if accepted.
• After accepting a store.upsert event, Partner Application must validate the store and provide a new external store id through v1/stores endpoint.
• Partner Application can then suspend, activate or invalidate a store given the external store id.
