Buyer Postback - Postback Conversions & Adding Data to Calls

Buyer Data Postback: Passing the call UUID and key to a buyer

Method 1: via webhook, for buyers not using SIP

Retreaver introduces the concept of call keys. Call keys are special API keys that are uniquely associated with a call. In conjunction with the call's UUID, the call key grants the holder the ability to update calls using the Retreaver API.

Adding an "answered" ping Webhook.

1. To add an answered ping, scroll to the "Webhooks" section of your campaign configuration. Click the green plus to add a new webhook group and set the trigger type to "answered".

2. To ensure the webhook is only triggered for calls routed to a specific buyer, use the Wizard to tag the webhook with your buyer's system_buyer_id. This webhook will now only be triggered for calls that have been accepted by the given buyer.

3. Your buyer will need to provide you with an HTTP endpoint capable of receiving and processing the request. Use replacement tokens to designate where the call UUID - [call_uuid] - and key - [call_key] - will be inserted in the URL.

You will need to work with your Buyer to determine the format of the URL itself, at minimum they will need the call UUID and key to pass data back to Retreaver. They will most likely also need the caller ID of the caller so they can correlate the call with the correct contact record in their systems.

Method 2: via SIP header

You can pass call UUIDs and keys to your buyers via webhook or through SIP headers.

If your Buyer is using a SIP-based phone number, the call UUID and key will be automatically passed to them via SIP headers. They should look for headers named X-PH-RetreaverUUID and X-PH-RetreaverKey in the SIP INVITE, and store these values for later use.

Triggering Conversions: Informing Retreaver of a conversion

To trigger conversions based on data posted back to us, you'll need to start by creating a postback conversion type on your Campaign edit page.

There are two variations between postback triggers:
A) Using a dynamic posted-back revenue value.
B) Using a string-matching conversion trigger with a pre-set revenue and payout.

Using a posted-back revenue value

Configuring a postback conversion with dynamic posted-back revenue value.

1) Firstly apply a filter tag to the "matches" field, this will instruct Retreaver to only allow a conversion postback if the call came from a certain publisher or was processed by a particular endpoint. At minimum, it is required that you tag at least one publisher or buyer to this conversion criteria, who will presumably trigger this postback.


2) The "Postback Timeout" field defines how many seconds after the call ends Retreaver should wait before deeming the call non-converted. Retreaver waits until a postback is received or the timeout is reached before firing any post-call webhooks. The default value is 600 seconds or 10 minutes.


3) You can set a modifier in the "posted-value payout modifier" field, if you wish to modify the posted back payout.

In order to multiply the value posted back by 0.8, enter *0.8 in the field. For a call with $10.00 in revenue, this would cause the payout to be set to $8.00. If the modifier field is left blank, the payout will be set to the revenue amount, which is likely not what you want.

Note: The string that you enter in the field will be evaluated operation-by-operation from left to right, and the operators can include * (multiplication), / (division), - (subtraction), and + (addition).

Note: In cases where you are not paying a publisher, set the payout to zero by setting the modifier to *0.

Note: You can also set a static payout value by multiplying the revenue by zero, then adding the static payout value as such: "*0+(payout_value)", example: *0+50.


4) Once you are finished configuring the postback criteria, update the campaign to apply your changes


5) View the postback instructions and generate a unique postback URL that your partners will use.

Note: The resulting created postback URL will remain identical between campaigns, provided that the "matches" field points to the same buyer. This allows the buyer to easily re-use the same postback URL across any campaigns they have been assigned to - provided that same conversion criteria is present on the campaign.


6) Your affiliate must then trigger the postback by sending a POST HTTP webhook request to confirm a conversion from their end, ensuring that they only trigger the postback once the call converts successfully. 

Example Posted-back buyer URL format:
https://retreaverdata.com/postbacks/a1b2c3d4?caller_number=1234567890&value=100

Using a conversion trigger with a static revenue and payout

Perhaps you have a call buyer that has agreed to pay you a certain price, but they simply want to post back to you whether or not there has been a sale. In this case, you can configure a Postback conversion to use a "conversion trigger", which is a keyword that we will look for in the Postback request URL from your buyer that will indicate a successful conversion has occurred:

In the above example, we used the "sale=true" conversion trigger keyword. With this keyword present in the postback , Retreaver will detect that a conversion has occurred and set the static revenue and payout you defined on the call.

Example Conversion trigger buyer postback URL format:
https://retreaverdata.com/postbacks/a1b2c3d4?caller_number=1234567890&match_trigger=sale=true

---

Associating the converted call with a UUID

By default, Retreaver buyer conversion webhooks rely on the supplied caller id, a call start timestamp in epoch time and the connected duration to attempt to match with the call that this conversion event is intended for.

To refine this further, users can supply a Retreaver 'call_uuid' to the buyer, which the buyer can then use to directly convert that specific call instead of attempting to match it based off the caller id/timestamp/connected duration.


Example Conversion trigger buyer postback URL format: https://retreaverdata.com/postbacks/a1b2c3d4?call_uuid=abc-123-def-467&value=REVENUE

---

Appending Tags with a postback request

Your buyer may include additional call tags/data points using the postback request by adding key=value parameters to the end of the postback request:

https://retreaverdata.com/postbacks/a1b2c3d4?call_uuid=abc-123-def-467&value=REVENUE&call_converted_via_postback=true

The 'call_converted_via_postback:true' tag would then be associated with the call.

 

Setting an appropriate postback timeout

When using postback conversions, all post-call webhooks are delayed until it has been decided whether or not the call has converted. By default, a timeout of 10 minutes after the call ends is set.

If we don't receive a postback from your Buyer, the call will be counted as non-converted and any non-conversion webhooks will be processed. If a conversion value is posted back after this happens, we'll mark the call as converted and process any conversion webhooks.

In cases where tag data is posted back that doesn't cause a conversion to be triggered, a non-conversion will not be triggered until the postback timeout expires.
