A client wants to calculate tax differently when an order is billed for a range of particular postcodes. They want to implement their own system…

The standard and most efficient method to create a conditional webhook in Adobe Commerce is by using the declarative webhooks.xml configuration file. This file allows developers to define rules that filter events based on the payload data. By adding a block, a developer can specify a condition on the billingaddress.postcode field. The regexp (regular expression) operator is the appropriate choice for matching a range or pattern of postcodes, ensuring the webhook only triggers for the specified criteria.

A. A plugin would intercept the webhook processing logic, which is less efficient than declarative filtering. The goal is to prevent the webhook from triggering at all, not to alter its behavior during processing.

C. This describes a non-standard and overly complex approach. There is no native concept of "linking" webhooks, and this method does not address the core requirement of how to make the new webhook conditional.

Configure webhooks:

Section: Conditional webhooks

Content: "You can configure a webhook to be sent only when certain conditions are met. The conditions are defined in the element of the webhooks.xml file. Each element contains a field

operator

and value." This section explicitly details the use of the element to create conditional webhooks.

webhooks.xml reference:

which include eq

and regexp. The regexp operator is specified for matching values against a regular expression

which is ideal for the postcode range requirement.
