What is a payload?

A payload is an additional tracking variable that affiliates can include in a tracking URL to store information about a visitor's click.

Payloads are commonly used to pass information such as:

• Search engine keywords
• Third-party tracking identifiers
• Advertising reference codes
• Other custom tracking values

When a customer registers, the payload value associated with the original click is stored and linked to the customer account within MyAffiliates.

Payloads allow affiliates to track additional information about visitors and conversions, helping them analyse traffic sources and optimise marketing campaigns.

Note: The maximum payload length is 512 characters - no spaces.
