Questions about startapp.com

How do I add startapp.com to app-ads.txt?

Add one line for each account startapp.com gives you: "startapp.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 startapp.com. The account ID must be the seller_id startapp.com lists for you in its sellers.json; startapp.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 startapp.com publish a sellers.json?

We found no sellers.json at https://startapp.com/sellers.json when we last looked on 9 October 2026. Lines naming startapp.com cannot be checked against it.

How many apps declare startapp.com in app-ads.txt?

90,965 apps in Stoqlab's data (delisted apps included) declare startapp.com: 10,901 with at least one DIRECT line and 88,627 with at least one RESELLER line, across 10,864 app-ads.txt files. Counts are recomputed daily.

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.
