gumroad - SKILL.md Agent Skill

name: gumroad description: > Use the `gumroad` CLI to look up and manage Gumroad data from the terminal. Trigger when the user asks about Gumroad products, files, file uploads, attachments, sales, subscribers, licenses, payouts, offer codes, webhooks, refund policies, or any Gumroad data lookup. Also trigger on "check my Gumroad", "look up a sale", "verify a license", "list my products", "how much have I made", "who bought", "recent sales", "refund a sale", "create a product", "upload a file", "attach a file to a product", "add a cover image", "set a product thumbnail", "get product content", "set product content", "upload product media", "publish a product landing page", "publish custom HTML", "clear custom HTML", "attach a file to a variant", "finish a failed upload", "abort an upload", "manage webhooks", "set refund policy", "check my refund policy", "check my earnings", "see my revenue", "who subscribed", "manage my store", "discount code", "coupon", "shipping status", "payout schedule", or any request to query or act on Gumroad data — even if the user doesn't say "Gumroad" explicitly but is clearly referring to their creator store or digital product sales. Do NOT trigger for Gumroad web UI, Rails, or codebase questions.

gumroad CLI

Use gumroad (Gumroad CLI) to query and manage Gumroad data.

Agent invariants

Always follow these rules:

Always pass --no-input to prevent interactive prompts from blocking.
Always pass --json for programmatic access.
Use --json --jq <expr> together to extract exactly what you need.
For operations that can prompt for confirmation (delete, refund, mutating admin actions, files abort, files complete replay, product updates that remove files, or products content set when omitted page IDs will be deleted), add --yes to skip confirmation.
Pass --quiet to suppress spinners and status messages.
Pass --dry-run to preview mutating requests without executing them.
Use --page-delay 200ms with --all to avoid rate limits on large datasets.
Prices are in whole currency units (e.g. --price 10.00 for $10), not cents. The CLI converts internally. Use --currency eur to change currency.
Products are created as drafts — use gumroad products publish <id> to make them live.
Product cover and thumbnail uploads support JPEG, PNG, and GIF. WebP is not supported by the API and the CLI rejects it before upload.
Product custom HTML landing pages use gumroad products page preview <id> ./landing.html to run the backend sanitizer without writing, gumroad products page publish <id> ./landing.html to store the page, gumroad products page clear <id> --yes to remove it, and gumroad products page url <id> to print the live URL. --dry-run only previews the CLI request body; it does not call the backend sanitizer. Inspect .sanitization_report in preview and publish JSON output for server-side changes.
Product rich content uses gumroad products content list <id> --json --no-input to inspect page IDs, gumroad products content get <id> --json --no-input to dump the shared rich_content page array, and gumroad products content set <id> content.json --dry-run --json --no-input to preview a whole-document replacement. Without an explicit path, whole-document set reads ./content.json; set --page reads ./page.json. Use --page <page_id> with get/set to edit one matching page object; set --page still sends a merged whole-document PUT. For per-variant content, pass both --variant <variant_id> and --category <cat_id>. Whole-document set deletes existing pages omitted from the JSON.
Custom HTML pages can use data-gumroad-field="name", data-gumroad-field="price", data-gumroad-field="description", and data-gumroad-action="buy". To preselect checkout state, add data-gumroad-option="<variant name>", data-gumroad-quantity="<integer>", data-gumroad-price="<decimal>", or data-gumroad-recurrence="monthly|quarterly|biannually|yearly|every_two_years". Production validates these values and falls back to product defaults when invalid. Prefer anchors for buy CTAs so production can add a checkout href; non-anchor buy elements also post to checkout.
If a command fails with a seller auth error, run gumroad auth status --json --no-input first. Agents can start seller auth with gumroad auth login --no-input and hand the printed approval URL to a human, or use an existing seller token via GUMROAD_ACCESS_TOKEN or gumroad auth login --with-token.
For admin commands in agents/CI, pass --non-interactive and set GUMROAD_ADMIN_TOKEN; interactive shells can store an admin token with gumroad auth login --web.

Response shapes

Most responses are wrapped in {"success": true, ...} with resource-specific keys:

user → .user
refund-policy view/set → .refund_policy
products list → .products[]
products view → .product
products content get → rich content page array directly, or one page object with --page
products content list → rich content page summary array directly
products content set → mutation envelope with .result
sales list → .sales[]
sales buyers → .buyers[] (email, name, purchase_count, last_purchase_date, utm_source, utm_medium, utm_campaign, utm_term, utm_content)
sales view → .sale
sales export → .status, .recipient_email
sales summary → .gross_cents, .net_cents, .breakdown[]
payouts list → .payouts[], payouts view/upcoming → .payout
subscribers list → .subscribers[], subscribers view → .subscriber
licenses verify → .purchase
offer-codes list → .offer_codes[]
variant-categories list → .variant_categories[]
variants list → .variants[]
files upload / files complete → .file_url
products create with media flags → .product plus .media[]
products update with media flags → .product plus .media[]
products covers add --image → .result.covers[], .result.main_cover_id, plus .result.media[]
products covers add --url → .result.covers[], .result.main_cover_id
products thumbnail set --image → .result.thumbnail, plus .result.media[]
products thumbnail set --url → .result.thumbnail
products page preview → .custom_html, .sanitization_report
products page publish / products page clear → .product.custom_html, .product.landing_url, .previous_custom_html, .sanitization_report
products update --custom-html → .product.custom_html, .product.landing_url, .previous_custom_html, .sanitization_report
Not every products write verb is flat: create, update, unpublish, and delete return top-level fields, but covers add, thumbnail set, and content set still wrap their payload in the {success, …, result} envelope — read those under .result
webhooks list → .resource_subscriptions[]
admin users info → .user
admin users affiliates → .affiliates[]
admin users comments list → .comments[]
admin users comments add → .comment
admin users compliance → .compliance_info, .info_requests[]
admin users credits add → .user_id, .credit.id, .credit.amount_cents, .credit.reason, .credit.crediting_user_id, .credit.created_at
admin users credits list → .credits[], .pagination.next
admin users radar → .radar_stats, .recent_efws[]
admin users purchases → .purchases[]
admin users related → .related_users[], .truncated, .per_signal_limit
admin users mark-compliant, admin users suspend, admin users suspend-for-tos-violation → .status, .message, .user_id
admin products flag-for-tos-violation → .status, .message, .user_id, .product_id
admin payouts scheduled create → .message, .user_id, .scheduled_payout
admin users refund-balance → .status, .message, .user_id, .count, .total_amount_cents, .currency
admin purchases view → .purchase
admin purchases search → .purchases[], .has_more, .limit
admin purchases lookup → .purchases[]
admin products list → .products[], admin products view → .product

Admin pagination models differ by command:

Cursor-paginated: admin users affiliates, admin users comments list, admin users credits list, admin users radar, admin users purchases, and admin purchases lookup return .pagination.next as a cursor string. Pass it back with --cursor.
Page-paginated: admin products list returns .pagination.next as an integer page number. Pass it back with --page; use --per-page for page size.
Capped, not continuable: admin users related returns at most 50 related users per signal. Always inspect .truncated; when any signal is true, the result hit the cap and there is no cursor/page to fetch the rest.
Capped, not continuable: admin purchases search returns .has_more when the server capped results. --limit is server-capped at 25 and there is no continuation token.

Bulk operations

When creating or updating many products:

Check existing products and permalinks first, then skip duplicates on re-runs.
Derive custom permalinks deterministically from source data so retries are idempotent.
Use --dry-run --json to preview generated requests, and ask the user to confirm before mutating more than 5 products.
Continue past per-product errors, collect each failure with its product/permalink, and summarize successes and failures at the end.
For product media failures after creation, retry with the command printed in the error, such as gumroad products covers add <id> --image ./cover.jpg.

In custom HTML, use Gumroad data attributes for live product values and checkout:

<h1 data-gumroad-field="name">Product name</h1>
<span data-gumroad-field="price">$0</span>
<p data-gumroad-field="description">Product description</p>
<a data-gumroad-action="buy">Buy now</a>
<a data-gumroad-action="buy" data-gumroad-option="Pro" data-gumroad-recurrence="yearly">Buy Pro - $99/year</a>
<button data-gumroad-action="buy" data-gumroad-quantity="2">Buy 2 seats</button>
<button data-gumroad-action="buy" data-gumroad-price="19.99">Pay $19.99</button>

Categories: products categories [--search <term>] returns label, path, and numeric ID. Prefer --category <path> for product create/update. --taxonomy-id remains supported when you already have the numeric ID, but it cannot be combined with --category.

Create flags: --name (required), --price, --type (digital|course|ebook|membership|bundle|coffee|call|commission), --currency, --pay-what-you-want, --suggested-price, --description, --custom-summary, --custom-permalink, --custom-receipt, --max-purchase-count, --category, --taxonomy-id, --tag (repeatable), --file (repeatable), --file-name (repeatable, aligned to --file), --file-description (repeatable, aligned to --file), --cover-image, --preview-image (repeatable), --thumbnail.

Update flags: --name, --price, --currency, --description, --custom-summary, --custom-permalink, --custom-receipt, --max-purchase-count, --category, --taxonomy-id, --tag (repeatable), --custom-html, --file (repeatable), --file-name, --file-description, --cover-image, --preview-image (repeatable), --thumbnail. Prefer products page preview/publish/clear/url for custom HTML page workflows; products update --custom-html remains supported as a low-level product update flag.

Use products update --file for shared product Content. It replaces existing rich content file embeds in place when they exist, or creates file embeds when the document has none; pass one --file per existing file embed and use products content get/set for structural content edits. For products with per-variant Content, use variants update ... --file for the specific variant you want to change.

Use --cover-image for the primary cover, repeat --preview-image for additional gallery/preview images, and --thumbnail for the card/library thumbnail. These media flags run the required two-step API flow: direct upload first, then attach by signed blob ID. For an existing product, products thumbnail set --url asks Gumroad to download and attach a public HTTP(S) image directly.

files — Upload and recover file attachments

# Upload a file and print the canonical Gumroad URL
gumroad files upload ./pack.zip --json --no-input
gumroad files upload ./pack.zip --name "Art Pack.zip" --json --no-input

# Abort an orphaned multipart upload
gumroad files abort --upload-id up-123 --key attachments/u/k/original/pack.zip --yes --json --no-input

files upload and files complete both return .file_url. When a JSON upload fails with recovery details, reuse .error.recovery with files complete to finish it or files abort to reclaim the orphaned multipart upload.
