Webhooks

Q: Do you guarantee delivery webhooks to our servers? What happens if we are down when a webhook is sent but not received? Is there any retry logic?

Currently webhooks are sent on a best effort basis, in other words, we send the webhooks and re-try but do not guarantee receipt. The webhooks currently will retry after the first failure (e.g. non-2xx HTTP status code), 4 times with exponential backoff. Specifically we retry after 2, 6, 14, 30 hours before giving up.

Q: Are you able to include more identifying information in the webhook so that we are able to identify which transactions are related to the end_user that is has been enriched/processed?

At present, we keep webhook details purposefully minimal as we cannot control the destination of the webhook and we do not want to send our customers' identifying information to undesireable destinations.
