Documentation
dispute.markets is a sandbox payment gateway for transactions, card-dispute lifecycles, evidence, and reports — built as a testbed for agentic workflows. The portal and the API expose the same surface; pick whichever fits the job.
Getting started
Sign up, verify your email, generate synthetic data, and walk a dispute from open to resolved.
Learn the domain
Chargebacks end to end — players, lifecycle, reason codes, evidence, fees, and prevention.
Dev panel
Generate, advance, and reset — the three buttons that drive the sandbox.
Team
Invite colleagues, give them roles, have several owners, and remove people. Synthetic accounts stay as they are.
Workspaces & environments
One workspace per environment: create, label, switch, leave and delete workspaces; keys and webhooks stay in theirs.
API reference
API keys, conventions, the audit trail and introspection API, webhooks, and an end-to-end testing guide with a downloadable example.
