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

Setup

1. Add the Composio MCP server to your client configuration:

https://rube.app/mcp

1. Connect your Gumroad account when prompted (API key authentication).
2. 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.
