Version: v3

Best Practices

  • Follow the API best practices. Learn more about our general guidance.
  • Use the Conversions API and Reddit Pixel together. This will improve conversion coverage, maximize campaign performance, and enable better targeting and optimization tools. Your measurement will be more resilient and adaptable to the shifting advertising landscape.

    Event deduplication is required for advertisers using both the Reddit Pixel and Conversions API.

  • Share as many matching signals as possible. Match keys are crucial to help attribute conversions to a Reddit ad engagement. These signals can be shared unhashed or pre-hashed. We strongly recommend sharing the IP address and click ID, and suggest including the email address, phone number, and user agent. If you’re integrating CAPI with the Pixel, we recommend sharing UUID.
  • Set up CAPI with a conversion access token. We recommend using this token over a developer access token because it’s non-expiring and simple to generate.
  • Verify events before sending production traffic. Learn more about event testing.
  • Stay within the rate limits. You’re limited to 1,000 requests/second, 1,000 events/request, and 10,000 events/second.
  • Avoid dual sending between versions. Sending the same events in both v2 and v3 may cause event double-counting.
