iGaming operators must satisfy regulatory bodies that their affiliate relationships are documented, monitored, and compliant. This is not optional recordkeeping -- it is a licensing condition. In regulated markets, your affiliate tracking system doubles as a compliance audit trail. What you can prove you tracked is as important as what you actually paid.
UKGC Affiliate Compliance Requirements
The UK Gambling Commission requires operators to maintain a documented register of all marketing affiliates, including their marketing authorization approval dates and evidence of ongoing compliance checks. Affiliates must not promote the operator until their marketing materials have been reviewed and approved. The operator is responsible for affiliate compliance -- not the affiliate.
Affiliate register: name, website, approval date, compliance check dates, and status for every active affiliate.
Marketing material approval log: every banner, landing page, and promotional claim must be approved before use.
Responsible gambling compliance: affiliates must display required safer gambling messaging and link to GamCare or equivalent.
Player origin tracking: the operator must be able to demonstrate which affiliate sent each player for licensing purposes.
Audit trail retention: minimum 5 years for all affiliate-related compliance documentation.
MGA (Malta) Affiliate Requirements
The Malta Gaming Authority requires operators to conduct due diligence on all business-to-business (B2B) relationships, which includes significant affiliates. MGA-licensed operators must be able to produce affiliate data on request during a compliance audit. The requirements are less prescriptive than UKGC but equally serious in enforcement.

What Your Tracking System Must Record
Compliance tracking goes beyond what is needed for commission calculations. The data your system must retain for regulatory purposes includes the full click record (timestamp, IP, affiliate ID), registration record, and all downstream player activity that could be relevant to a licensing investigation. A player complaint about responsible gambling that traces back to an affiliate's marketing creates an audit chain you must be able to reconstruct.
Click-level data: timestamp, affiliate ID, campaign ID, landing page URL, IP address (anonymized per GDPR)
Registration data: timestamp, affiliate attribution, jurisdiction, player age verification status
First deposit data: amount, timestamp, payment method, affiliate ID
Responsible gambling events: self-exclusion requests, deposit limits, player cooling-off periods -- tied to affiliate attribution for reporting
Self-exclusion events must be immediately processed across all affiliated brands in markets like the UK (GAMSTOP). If an affiliate sends a player who is on GAMSTOP's self-exclusion list and your system fails to flag it, the operator is liable -- not the affiliate. Your tracking system needs real-time GAMSTOP integration, not batch checks.
Build compliance event logging into your affiliate platform from day one. Retrofitting compliance data capture into an existing system is significantly more expensive than designing for it at the start. At minimum, capture affiliate ID on every player event -- including responsible gambling triggers.
Key Takeaways
UKGC requires a documented affiliate register, pre-approved marketing materials, and 5-year data retention -- all of which must be provable in an audit.
The operator is responsible for affiliate compliance in regulated markets -- not the affiliate. Your tracking system is your evidence trail.
MGA requires similar rigor to UKGC with fewer prescriptive rules; Curacao operates with lighter requirements but growing scrutiny.
Responsible gambling events -- self-exclusions, deposit limits -- must be captured against affiliate attribution for compliance reporting.
Build compliance data capture into your platform from launch. Retrofitting it into existing systems is expensive and often incomplete.
