Reversal Postback Setup For Processing Canceled Transactions

Automatically track and reverse canceled, refunded, or invalid transactions by setting up Reversal Postbacks using conversion IDs, order numbers, transaction IDs, or email addresses.

Overview: What is a Reversal Postback?

A reversal postback is an automated notification sent between servers when transactions need to be canceled, refunded, or marked invalid. This ensures accurate tracking and proper commission adjustments for affiliates, partners, and your business.

Available Tracking Methods

Choose the right method based on your needs:

By Conversion ID

https://your-everflow-tracking-domain/reversal?conversion_id=CONVERSION_ID

This reverses a single specific conversion

By Order ID

https://your-everflow-tracking-domain/reversal?order_id=ORDER_ID

Reverses the conversion linked to this order ID

Heads Up! All conversions with this order ID will be reversed.

By Transaction ID (Options)

With Event ID=0: https://your-everflow-tracking-domain/reversal?transaction_id=TRANSACTION_ID&event_id=0
- Only reverses the specific conversion tied to this Transaction ID
Without Event ID: https://your-everflow-tracking-domain/reversal?transaction_id=TRANSACTION_ID
- Reverses ALL events linked to this Transaction ID
With Event ID or Advertiser Event ID: https://your-everflow-tracking-domain/reversal?transaction_id=TRANSACTION_ID&event_id=EVENT_ID
- Reverses conversions matching both Transaction ID and Event ID

By Email

Email Address Only: https://your-everflow-tracking-domain/reversal?email=EMAIL
- Reverses ALL conversions associated with this email
Email with Event ID: https://your-everflow-tracking-domain/reversal?email=EMAIL&event_id=EVENT_ID
- Reverses conversions for this email, but only for the specific event
Email with Advertiser Event ID: https://your-everflow-tracking-domain/reversal?email=EMAIL&adv_event_id=ADV_EVENT_ID
- Reverses conversions for this email, but only for that specific Advertiser Event

Heads Up! If you are using &verification_token= in the regular conversion postback, please note that it must also be added to the reversal postback for it to function properly.

Reporting

If you are using an eCommerce integration (Shopify, ClickFunnels or WooCommerce), your reversals will appear in the Refund Report.

You can see all conversions (including rejected conversions that were reversed) in the Conversion Report. To access this report, go to Reporting → Conversion. You can then filter your results to show conversions that have a Rejected status, if needed.
