# Postback

For Keitaro to record a conversion in statistics, the tracker must receive an incoming Postback with its own subid click. The Postback, depending on the type of scheme, is sent:

# Postback processing

How Keitaro processes postbacks?

# Getting Postback URL

Postback URL is a link to which the sender (direct advertiser, affiliate network, etc.) transmits data on conversion, that is the fact of its commitment, conversion parameters (amount of payment, status, etc.)

If you need Postback URL for affiliate network, please read Affiliate Network Postback.

  1. To create an individual link, open Maintenance → Postback URL.

  2. Copy the Postback URL and add the necessary parameters from Postback Options.

# Postback parameters

  • subid (required). Tracker click identificator. Used by the tracker to understand which click to record the conversion.
  • tid. Transaction ID. The identifier of the serial number of the target action. For example tid=2 means a second deposit from one player or the purchase of additional training course materials by a person who has already purchased the main material. This is an indication of an additional sale.
  • payout (or revenue). Amount of conversion payment.
  • cost. Conversion cost for CPA and RevShare cost models).
  • status (default is sale). Conversion status.
  • currency. Payout currency (usd, eur, etc.).
  • From sub_id_1 to sub_id_15. Additional free parameters to update the click parameters. Any string and number values are recorded.
  • return. Return custom success message. For example, with &return=OK Keitaro will show 'OK'.
  • sale_status, lead_status, rejected_status. Read Status transformations section.
  • ignore_status. List of statuses that must be ignored. Example, ignore_status=ping,test.

# Conversion status

Keitaro supports and reports the following statuses:

  • lead. Payout is not confirmed. The income on such conversions is displayed in the Revenue (hold) metric.
  • sale. Payout is confirmed. The income on such conversions is displayed in the Revenue (confirmed) metric.
  • rejected. Payout is cancelled. The income on such conversions is displayed in the Revenue (rejected) metric.
  • rebill - Tracker has received a new transaction on subid, already recorded as Sale conversion in the tracker. For example, a repeated deposit. When receiving a unique transaction identifier in the &tid= placeholder in the postback, the tracker reports such conversion as a Rebill. Income from such conversions is summed up in the Revenue (confirmed) metric, in case Rebill is turned on in the offer settings.

See also Rebills.

# Status transitions

  • lead to sale.
  • lead to rejected.
  • sale to rejected.

# Custom statuses

Custom statuses can be transformed to Keitaro statuses. Keitaro stores original status as original_status.

# Status transformations

Example:

In the Affiliate Network placeholders list, registrations are listed as new and reg. Based on the available Keitaro conversion statuses, for the tracker registration is a Lead. It is necessary to specify the corresponding training in the postback link, and when receiving one of the new or reg statuses, the tracker will record the Lead.

status=new&lead_status=new,reg&sale_status=billed&rejected=canceled,fake
1
  • Transforms reg and topup to lead.

  • Transforms billed to sale.

  • Transforms cancelled and fake to rejected.

  • If you receive a conversion with status=new or status=reg, tracker will record it in reports as Lead, because it is specified in the link status=new&lead_status=new,reg

The same for other statuses, for example Sale.

By getting status=billed&sale_status=billed the tracker understands that billed is recorded as a Sale.

Keitaro stores raw status as "Original status" (original_status column).

# Rebills

Keitaro handles upsells when

  • Tracker already stores conversion with status=sale on the subid of this click
  • Offer allows Rebill. See Offer Settings page.
  • Postback includes tid and it's unique.
  • Postback has status with value either sale or rebill.

# Convert currency

The tracker keeps statistics in one currency specified in Service-Settings-Currency. Pass the currency in the Postback URL in the currency= placeholder, and the tracker will convert the postback payment amount to the currency specified in the settings. Example:

https://example.com/key/postback?status=lead&payout=10&currency=EUR
1

Now Keitaro does not store payouts in different currencies for each campaign separately. The currency of the statistics is set at the tracker level. The tracker converts the payout amount from the currency specified in the Postback URL.

How Keitaro converts currency?

Keitaro requests daily an external web service for all the currency rates.

Why sending test postback doesn't work?

Usually affiliate networks don't send real subid. That's why Keitaro ignores these postbacks.

Postback key

That is a unique for each tracker string. It protects Keitaro of receiving non-authorized postbacks.

To change postback key, edit /var/www/keitaro/application/config/config.ini.php and set it in the line:

postback_key = "CUSTOM_KEY"
