In this case, a custom effect allows you communicate any data from Talon.One to the integration layer in the form of a structured effect.
Like any other effect, custom effects are returned when you call the Update customer session when a rule is valid.
Understanding the context
Let's imagine we run a company that rents bicycles by the minute and we want to reward customers with free minutes when they use a coupon code.
To do this, we must create a rule with the following logic:
- If the coupon is valid then send the awarded number of minutes to the integration layer.
No core effects provides information about awarded minutes, so let's create a custom effect to cover our use-case.
Creating a custom effect
Let's create our Award minutes custom effect. It will appear in the Rule Builder as a new effect type.
- In the bottom-left of the Campaign Manager, click Account > Tools > Custom Effects.
- Click Create Custom Effect.
- In API name, type
- In Rule Builder name, type
Award minutesis the name of the effect. It appears in the effects section when we create a rule.
- In Applications, select your Application.
Let's add parameters to our effect.
Parameters represent the data of the effect that can be edited from the Rule Builder's UI.
In our case, we need a number of minutes and the ID of the customer involved. To do this we only need one parameter because:
- The number of minutes should be customizable from the Campaign Manager's Rule Builder.
- The profile ID is set by the integration layer without user input when we create sessions so we do not need a parameter.
Let's create the parameter:
- In Param type, select number.
- In Param name, let's type a user-friendly name such as
minutes. This will appear in the Rule Builder.
- In Param Description, let's type
The number of minutes awarded.. This will appear in the Rule Builder.
Creating the payload
We've defined the parameter for the users of the Rule Builder, now let's define the payload for our integration layer.
We want the effect to contain:
- The number of minutes defined with a parameter.
- The profile ID represented by the profile's
To do this, we use the following payload:
Create and our effect is ready for use.
Creating a rule
Let's create the rule to award minutes.
- Open the Rule Builder in your campaign and create a rule:
- Condition: Coupon code is valid
- Effect: Award minutes
- Edit the value of the minutes parameter.
- Save and enable the Campaign.
When the rule triggers, the integration layer receives the following example payload:
"ruleName": "Award minutes",
"name": "Award minutes",
We can now parse the response to extract the data we needed. Notice we get 2 effects, the
acceptCoupon effect when a coupon is valid and a
customEffect with the data
we need: the awarded minutes and the customer ID.
