ironSource (Unity)

Add one line for each account ironSource (Unity) gives you: "ironsrc.com, YOUR_ACCOUNT_ID, DIRECT, 79929e88b2ba73bc". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through ironsrc.com. The account ID must be the seller_id ironSource (Unity) lists for you in its sellers.json; ironSource (Unity) 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.

Yes. Its file at https://www.ironsrc.com/sellers.json listed 5,200 sellers when we last read it on 9 October 2026: 5,200 publishers, 0 intermediaries and 0 listed as both; 0% are confidential.

82,293 apps in Stoqlab's data (delisted apps included) declare ironsrc.com: 76,259 with at least one DIRECT line and 42,518 with at least one RESELLER line, across 9,425 app-ads.txt files. Counts are recomputed daily.

52% of the app-ads.txt lines naming ironsrc.com carry "79929e88b2ba73bc" in the fourth field. The field is optional; the IAB Tech Lab ads.txt 1.1 specification says identifiers in sellers.json supersede it, so a missing or different value does not make a line invalid.

Of 29,882 lines naming ironsrc.com, 15,729 contradict its sellers.json. The most common case is "RESELLER but publisher" (12,242 lines): If the account is yours, declare it DIRECT. If a partner holds it, ask ironSource (Unity) why the account is listed as PUBLISHER.

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.
