Gumroad Automation

When to use this skill

Use Gumroad Automation when an AI agent needs a reusable SKILL.md workflow for this job: Automate Gumroad product management, sales tracking, license verification, and webhook subscriptions using natural language through the Composio MCP integration.

When not to use it

Skip Gumroad Automation when the task is outside the productivity category, or when a more specific skill in this directory already covers the same workflow with clearer triggers.

How to install

1. Personal install: create ~/.claude/skills/gumroad-automation/SKILL.md (and any bundled scripts) so Claude Code, Claude Desktop, and compatible agents can load it in every project.
2. Project install: commit the same folder at .claude/skills/gumroad-automation/ so teammates get the skill with the repo.
3. Restart the agent session after copying files so it re-scans the skills directory, then ask for the task in words that match the skill description.

What this skill does

# Gumroad Automation

Automate your Gumroad storefront -- list products, track sales, verify licenses, and manage real-time webhooks -- all through natural language commands.

**Toolkit docs:** [composio.dev/toolkits/gumroad](https://composio.dev/toolkits/gumroad)

---

## Setup

1. Add the Composio MCP server to your client configuration: ``` https://rube.app/mcp ``` 2. Connect your Gumroad account when prompted (API key authentication). 3. Start issuing natural language commands to manage your Gumroad store.

---

## Core Workflows

### 1. List All Products Retrieve every product in your authenticated Gumroad account to get product IDs for downstream operations.

**Tool:** `GUMROAD_LIST_PRODUCTS`

**Example prompt:** > "List all my Gumroad products"

**Parameters:** None required -- returns all products for the authenticated account.

---

### 2. Track Sales with Filters Retrieve successful sales with optional filtering by email, date range, product, or pagination.

**Tool:** `GUMROAD_GET_SALES`

**Example prompt:** > "Show me all Gumroad sales from January 2025 for product prod_ABC123"

**Key parameters:** - `after` -- ISO8601 date/time to filter sales after (e.g., `2025-01-01T00:00:00Z`) - `before` -- ISO8601 date/time to filter sales before - `email` -- Filter by customer email address - `product_id` -- Filter by specific product ID - `page` -- Page number for paginated results (minimum 1)

---

### 3. Verify License Keys Check if a license key is valid against a specific product, inspect usage count, or verify membership entitlement.

**Tool:** `GUMROAD_VERIFY_LICENSE`

**Example prompt:** > "Verify license key ABCD-EFGH-IJKL-MNOP for product prod_ABC123"

**Key parameters (all required):** - `product_id` -- The product ID to verify against (required for products created on/after Jan 9, 2023) - `license_key` -- The license key string (e.g., `ABCD-EFGH-IJKL-MNOP`) - `increment_uses_count` -- Whether to increment usage count (defaults to true)

---

### 4. Subscribe to Webhook Events Set up real-time event notifications by subscribing your endpoint URL to specific Gumroad resource events.

**Tool:** `GUMROAD_SUBSCRIBE_TO_RESOURCE`

**Example prompt:** > "Subscribe my webhook https://example.com/hook to Gumroad sale events"

**Key parameters (all required):** - `resource_name` -- One of: `sale`, `refund`, `dispute`, `dispute_won`, `cancellation`, `subscription_updated`, `subscription_ended`, `subscription_restarted` - `post_url` -- Your endpoint URL that receives HTTP POST notifications

---

### 5. List Active Webhook Subscriptions Review existing webhook subscriptions for a given resource type before adding new ones to avoid duplicates.

**Tool:** `GUMROAD_GET_RESOURCE_SUBSCRIPTIONS`

**Example prompt:** > "Show all my active Gumroad webhook subscriptions for sale events"

**Key parameters (required):** - `resource_name` -- One of the eight supported event types (e.g., `sale`, `refund`)

---

## Known Pitfalls

- **Product ID required for license verification**: Products created on or after January 9, 2023 require the `product_id` parameter. Older products may work without it but providing it is recommended. - **Pagination on sales**: Sales results are paginated. Always check if more pages exist by incrementing the `page` parameter. - **Webhook deduplication**: Before subscribing to a resource, use `GUMROAD_GET_RESOURCE_SUBSCRIPTIONS` to check for existing subscriptions and avoid duplicate webhooks. - **ISO8601 date format**: Date filters on sales must use ISO8601 format (e.g., `2025-01-01T00:00:00Z`), not plain dates.
