Pass GTaro click IDs to your tracker and send conversions back with one S2S postback. You will see conversions by source and sub ID in both places and can optimize placements on real results. All you need is a GTaro campaign and any tracker that supports S2S postbacks.
GTaro opens your tracker link and fills in {postbackid} with a click token, plus the source and sub ID macros you added.
Your tracker stores the click ID
The tracker saves the GTaro click ID as the traffic source's external ID and sends the visitor on to your offer.
A conversion happens
The tracker calls the GTaro postback URL with the same click ID. The conversion appears in your GTaro statistics right away.
Tracking macros
Add these macros to the link you paste into the Redirect URL of your GTaro campaign. GTaro replaces each one with a real value on every click. The same macros work in every format: popunder, push, native, banner and direct link.

What it passes
Example
Suggested parameter
{postbackid}
Click token for the S2S postback. It encodes the placement, country and day of the click, so clicks from the same placement on the same day share it. Required for conversion tracking
a URL-safe string of about 60–100 characters
cid
{source}
ID of the traffic source (supply endpoint) the visit came from
23
source
{subid}
Sub ID of the placement inside that source
1494502
subid
{campaign}
ID of your GTaro campaign
459
campaign
{website}
ID of the publisher's website
169
site
{publisher}
ID of the publisher

pub
A placement is identified by the pair {source} + {subid}. Pass both to your tracker: when a placement does not convert, you can block it in your GTaro campaign as SOURCE-SUBID, for example 23-1494502.
When a conversion happens, your tracker sends a GET request to this URL. Replace {EXTERNAL_ID_TOKEN} with your tracker's token for the traffic source click ID (see the table below).
The postback takes only the click ID. GTaro counts conversions; payouts stay in your tracker.
A successful postback returns {"success":"Conversion stored successfully"}. If you see {"error":"Invalid format"}, the click ID was cut or changed on the way.
Send one postback per conversion. A repeated postback with the same click ID is counted as another conversion.
The click ID does not expire: a postback is accepted however long after the click the conversion happens.

Any other tracker
Create a custom traffic source named GTaro Ads.
Put {postbackid} in the field for the traffic source click ID (often called External ID or Click ID).
Map {source} and {subid} to two custom parameters.
Set the traffic source postback to https://gtaroads.net/postback?id= followed by your tracker's click ID token.
BeMob uses {externalId}: tick the statuses you want to send in the source settings, only Approved is ticked by default. ClickFlare uses {external_id} and needs Traffic Source Postback URL turned on with the conversion event selected.
Test your setup
Launch your GTaro campaign with a small daily budget.
Open your tracker's report: clicks should arrive with a filled click ID, source and sub ID. If you see the literal text {postbackid}, the macro is in the wrong field or misspelled.
When the first conversion comes in, check the tracker's postback log. GTaro answers {"success":"Conversion stored successfully"}.
In your GTaro account, open Statistics: the Conversions column shows the conversion right away. Group by source and sub ID to compare placements.
Troubleshooting
Conversions are in my tracker but not in GTaro
Check the postback log in your tracker. No request sent: the traffic source postback is off or filtered by status. Invalid format: the click ID did not reach the tracker in full; make sure {postbackid} is the value of the external ID parameter and nothing shortens it.
I see more conversions in GTaro than in my tracker
Your tracker sends the postback more than once for the same click, for example on every status change. Send only the final status or only the first conversion, using the options described for your tracker above.
The click ID arrives as the text "{postbackid}"
The macro is written incorrectly or placed in the offer URL instead of the GTaro Redirect URL. Macros are filled in only in the Redirect URL of your GTaro campaign, with curly braces and in lowercase.
Can I send the payout in the postback?
No. GTaro stores conversions without amounts. Keep payouts and ROI in your tracker; in GTaro use conversion counts by source and sub ID.
How do I stop a placement that does not convert?
Find its source and sub ID in your tracker and add SOURCE-SUBID to the blacklist of your GTaro campaign, for example 23-1494502.
