Questions about addefend.com
How do I add addefend.com to app-ads.txt?
Add one line for each account addefend.com gives you: "addefend.com, YOUR_ACCOUNT_ID, DIRECT". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through addefend.com. The account ID must be the seller_id addefend.com lists for you in its sellers.json; addefend.com will give it to you. Put the file at the root of the domain named as your developer website in the App Store and Google Play listings.
Does addefend.com publish a sellers.json?
Yes. Its file at https://portal.addefend.com/sellers.json listed 163 sellers when we last read it on 10 October 2026: 155 publishers, 8 intermediaries and 0 listed as both; 0% are confidential.
How many apps declare addefend.com in app-ads.txt?
108 apps in Stoqlab's data (delisted apps included) declare addefend.com: 27 with at least one DIRECT line and 86 with at least one RESELLER line, across 68 app-ads.txt files. Counts are recomputed daily.
Why do addefend.com lines fail verification?
Of 142 lines naming addefend.com, 93 contradict its sellers.json. The most common case is "RESELLER but publisher" (93 lines): If the account is yours, declare it DIRECT. If a partner holds it, ask addefend.com why the account is listed as PUBLISHER.
What is the difference between DIRECT and RESELLER?
DIRECT means the publisher owns the account; RESELLER means an intermediary sells the inventory on the publisher's behalf. DIRECT lines should match a PUBLISHER entry in the network's sellers.json, RESELLER lines an INTERMEDIARY entry.
