Win disputes with a letterhead evidence PDF

Pays for itself. A lost dispute is usually the network/processor fee plus the revenue. Organizing one mid-ticket defense into a clean letterhead pack is the no-brainer math versus Plus or a PDF pack. We do not invent win-rate percentages.

Not legal or financial advice. This page is for merchants assembling legitimate defense packets. It is not a substitute for Stripe docs, card-network reason-code guides, your acquirer playbook, a licensed attorney, or your judgment. It does not coach cardholders on filing disputes, inventing claims, or keeping goods they reverse.

Live now: dump case details below → download a branded evidence PDF. The same HTTP endpoint is callable by your agent (JSON in, PDF bytes out). Brand: Pingpong at pingpongit.com. Not getpingpong.ai.

Generate evidence PDF Agent API Plus / Pro

Generate your evidence PDF

Fill the fields a reviewer expects on page one: merchant letterhead, case identifiers, reason-mapped narrative, and an evidence index. Optional logo URL embeds when the image is a reachable PNG/JPEG.

Continue on Plus

Pricing (locked): first PDF free per browser/device → then Plus required ($19.99/mo includes 5 PDFs/mo; extras $12 or 10-pack $99; Pro includes 25/mo). Agents: metered ppk_ key. Full table: pricing.

Callable by your agent

Dedicated landers: API for agents, dispute evidence API, Stripe dispute API.

Strategic no-brainer: your ops agent (or support bot) already has the case JSON. Do not paste into a chat UI when you can POST once and attach the PDF. Same contract as the form.

Endpoint: POST https://pingpongit.com/api/dispute-evidence-pdf

Auth / payment (simple):

  • Wedge: no key → first PDF free per browser/device (cookie + durable claim). After that, Plus CTA (402) unless you send a key.
  • Agents: send X-PingPong-Key: ppk_… or Authorization: Bearer ppk_…. Issue keys at /api/dashboard (see developer docs). Metered against API quota; keyed calls also hourly rate-limited.
  • Response: application/pdf bytes. Headers include X-Pingpong-Billing, X-Pingpong-Job-Id, and after free use X-Pingpong-Plus-Cta.

Why loose screenshots fail reviewers

A reviewer at the issuer or network is not your teammate. Unlabeled JPEGs and a polite single-model letter read as noise. Stripe-shaped and network-shaped evidence rules reward the same object: a coherent narrative plus files that speak to the reason code. Delivery claims need delivery status, not label-created. Cancel fights need the cancel path the customer could see. Refund-already-issued cases need the credit.

What the letterhead pack should look like

Company logo and legal name on the first page. Case ID, reason code, amount, and order ID in a header block. A short narrative that answers the claim without insulting the cardholder. An evidence index that names each attachment. Networks do not publish a magic win percentage for letterhead; they reward clarity and fit. We do not invent case-win percentages on this page.

Pricing

PDF path: first PDF free per browser/device → then Plus required ($19.99/mo includes 5 PDFs/mo) → extras $12 each or 10-pack $99 → Pro includes 25 PDFs/mo. After the free wedge, the form shows a hard Plus CTA (or use a metered ppk_ agent key).

Also live: first eligible web Pingpong is free. Web Plus $19.99/month or Web Pro $124.99/month. iOS: three free Pingpongs, then Plus $24.99/month or Pro $59.99/month. Full pricing.

Hub: dispute cases. Agent APIs: API for agents, dispute evidence API. Not the buyer page before you file a chargeback.

Hard line: legitimate merchant defense only. Not coaching to fabricate tracking, deny a valid refund, or pressure customers who correctly reversed an unauthorized charge. If the sale was wrong, refund and close.

Again: not legal or financial advice. A tight letterhead pack is how operators submit organized evidence. It is not a substitute for processor docs, network rules, or a licensed advisor.
