Inventory and ownership
Channels, markets, publishers, apps or venues, available formats and the partner’s relationship to that inventory.
SUPPLY CHAIN TRANSPARENCY
Know where your media comes from.
JCD plans and buys media for advertisers and agencies. We work with SSPs and media owners to understand the inventory, buying route and reporting available for each campaign.
Our role: media planning and buying.
We represent the campaign’s buying requirements: audience, markets, formats, budget and delivery goals. Third-party inventory belongs to the media owner or supply partner.
We agree the buying arrangement with each partner. Account details, deal setup, reporting and billing responsibilities are confirmed during onboarding.

Buying route
The platform, seller accounts and intermediaries involved in the proposed buy, plus available deal types and commercial terms.
Quality and suitability
The partner’s invalid-traffic controls, content policies, placement restrictions and available verification options.
Delivery and billing
Reporting fields, data sources, DOOH proof-of-play where available, billing terms and how discrepancies are handled.
Seller records and supply-chain information.
For applicable programmatic inventory, ads.txt and app-ads.txt identify authorized sellers. A platform’s sellers.json identifies its sellers, while the OpenRTB SupplyChain object describes the sellers involved in a bid request.
For an inventory review, provide the relevant publisher or app details, exchange domain, seller account IDs and seller records. For OpenRTB connections, include a sample request and SupplyChain object where applicable. Requirements depend on the inventory and buying route.
Use the identifiers agreed with the relevant platform during onboarding. This page does not provide an ads.txt entry or seller account ID to copy.
