addPostback

Adds a postback rule to be triggered by certain Leanplum message or A/B test events. The maximum number of postbacks allowed is three per app. This method requires your data export API clientKey.

See type and channels below for all possible events that can trigger postbacks. To see what values can be returned by the resulting POST request, see postbackUrl with an example template below.

Postback retry policy: If your app is unresponsive, Leanplum's request will timeout in 30 seconds. If the error code is 5xx, we will retry up to 9 more times with exponential backoff, starting from 1 hour, up to 10 hours. If all 10 times fail, the data is lost.
