Common errors with mgid.com lines
-
Seller ID not found
23,499 lines
Ask mgid.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.
-
Seller type BOTH
303 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.
-
RESELLER but publisher
31 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask mgid.com why the account is listed as PUBLISHER.
-
DIRECT but intermediary
3 lines
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask mgid.com to list it as PUBLISHER.

Questions about mgid.com
How do I add mgid.com to app-ads.txt?
Add one line for each account mgid.com gives you: "mgid.com, YOUR_ACCOUNT_ID, DIRECT, d4c29acad76ce94f". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through mgid.com. The account ID must be the seller_id mgid.com lists for you in its sellers.json; mgid.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 mgid.com publish a sellers.json?
Yes. Its file at https://www.mgid.com/sellers.json listed 2,551 sellers when we last read it on 9 October 2026: 2,540 publishers, 6 intermediaries and 5 listed as both; 0% are confidential.
How many apps declare mgid.com in app-ads.txt?
80,228 apps in Stoqlab's data (delisted apps included) declare mgid.com: 25,713 with at least one DIRECT line and 78,740 with at least one RESELLER line, across 9,679 app-ads.txt files. Counts are recomputed daily.
What is the certification authority ID for mgid.com?
100% of the app-ads.txt lines naming mgid.com carry "d4c29acad76ce94f" 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.
Why do mgid.com lines fail verification?
Of 24,298 lines naming mgid.com, 23,533 contradict its sellers.json. The most common case is "Seller ID not found" (23,499 lines): Ask mgid.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.
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.
