Common errors with zeststack.com lines
-
Seller type BOTH
187 lines
The account is listed as BOTH, so sellers.json alone cannot tell a buyer which relationship applies. Nothing to fix on your side; buyers usually look at the seller's domain.
-
DIRECT but intermediary
108 lines
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask zeststack.com to list it as PUBLISHER.
-
Seller ID not found
47 lines
Ask zeststack.com for the account ID it lists for you in its sellers.json, correct the line, or remove it if you no longer work with them. Buyers that check sellers.json drop these paths.

Questions about zeststack.com
How do I add zeststack.com to app-ads.txt?
Add one line for each account zeststack.com gives you: "zeststack.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 zeststack.com. The account ID must be the seller_id zeststack.com lists for you in its sellers.json; zeststack.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 zeststack.com publish a sellers.json?
Yes. Its file at https://www.zeststack.com/sellers.json listed 358 sellers when we last read it on 10 October 2026: 352 publishers, 4 intermediaries and 2 listed as both; 0% are confidential.
How many apps declare zeststack.com in app-ads.txt?
20,823 apps in Stoqlab's data (delisted apps included) declare zeststack.com: 987 with at least one DIRECT line and 20,546 with at least one RESELLER line, across 1,979 app-ads.txt files. Counts are recomputed daily.
Why do zeststack.com lines fail verification?
Of 2,475 lines naming zeststack.com, 199 contradict its sellers.json. The most common case is "DIRECT but intermediary" (108 lines): If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask zeststack.com to list it 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.
