Publish
The advertiser hosts a machine-readable file on its own domain and names the team responsible for the program.
Open non-commercial project
Offer rules should be clear to everyone
Affiliate.txt is an open format where an advertiser publishes program rules once, while publishers, networks and anti-fraud services read the same current version.

How it works
The advertiser publishes rules on its own domain
The file does not replace a contract or affiliate platform. It gives every participant one public place to verify current terms and their change history.
Connect
Publishers, CPA networks and tools read offer status, traffic rules, contacts and current assets.
Verify
When a rule changes or a dispute arises, all sides refer to a specific public version and date.
For the whole market
One version of the rules for every participant
The format is for publishers, advertisers, affiliate managers and anti-fraud teams, regardless of which network they use.
Publisher
Sees current terms, allowed sources, contacts and changes before sending traffic.
Advertiser
Updates rules once and receives a more transparent, predictable affiliate channel.
Affiliate manager
Onboards partners faster and spends less time repeating the same updates.
Anti-fraud team
Checks an event against the rules that were actually in force at that time.
Affiliate.txt does not replace CPA networks — it gives them a common format for offer rules
Why now
Rules change faster than they reach partners
The same offer is described differently across several CPA networks. One misses a new brand-bidding restriction, another keeps an outdated creative, and a third has no clear contact for evidence.
Affiliate.txt makes the source verifiable: who owns the program, which sources are allowed, what is prohibited, when the rules changed and how to appeal a decision.
