Legacy v1

The API reference contains active v1 and v2 operations. A /v1 path is not deprecated unless the operation is marked deprecated: true in OpenAPI.

Retired operations

The v1 listing operations return 410 Gone. Use the corresponding v2 product operation:

/v1/listings                         → /v2/products
/v1/listings/search                  → /v2/products/search
/v1/listings/batch                   → /v2/products/batch
/v1/listings/{listing}               → /v2/products/{product}

The v1 invoice operations also return 410 Gone. Replace the /v1/invoices prefix with /v2/invoices; checkout, issue-replacement, mark-completed, and mark-voided operations have direct v2 counterparts.

Each retired OpenAPI operation includes deprecated: true and an x-sellapp-replacement method/path value for automated migration tooling.

Active v1 resources

Coupons, sections, tickets, feedback, and blacklists currently retain active v1 operations. Continue using their documented paths until a replacement is announced in the API changelog.
