For example, if you have two SMS integrations - Twilio and MessageBird, you may have rules to
  • Split traffic between the two
  • Use one as fallback
  • Condition based: If geography = ‘EU’ -> send using MessageBird, otherwise use Twilio.
You can create such rules for a channel and select them when creating an Event. Navigate to our Integration Rules section on the dashboard to start creating rules. We will highlight a few common types of rules as examples in this doc.
Integration Rules work within a channel and not cross-channel. For example, you can only define rules that decide how to use Twilio and MessageBird to send an SMS. If you want to create a cross channel rule like: Send an Email if SMS fails, then you should check our doc on adding channel fallbacks.
Integration Rules can be re-used across your Events. You can do this by Edit/Create Event and selecting the rule (in the Send Via list) for a channel. This allows you to edit your rule anytime directly on the dashboard without having to write a line of code or update any event.

​
Rule Example #1: Use multiple integrations with priority

Consider the example, where you want to send SMS with the following configuration:
PriorityIntegrationCondition
Priority 1TwilioDefault use Twilio
Priority 2PlivoIf Twilio API fails or Twilio fails to deliver SMS within 30s
Priority 3KaleyraIf Plivo API fails or Plivo fails to deliver SMS within 20s
You can easily create a rule with the above configuration on the dashboard: Priority Rule

​
Rule Example #2: Split traffic between integrations

Consider the example, where you want to split SMS traffic between two integrations: Send 70% traffic to Twilio, rest 30% on Kaleyra. You can create a rule to spilt traffic as shown below. traffic_split_percent is a reserved keyword and can directly be selected in the condition. Your Send Event API remains as is and you need not pass any extra field to enable this rule. Traffic Split

​
Rule Example #3: Conditional

You can create conditional rules if you have want to select an integration based on a set of conditions. Consider the example, where you have users across geographies and you want to use Twilio for users in US and MessageBird for users in Europe. You can create a conditional rule as shown below: Conditional Rule You can add multiple IFs in a condition, like IF user_id >= 1000 AND user_type = merchant. You will have to pass the value of all conditional key fields in the data payload of the Send Event API. Raven will use that value to evaluate the condition and use the correct set of integrations. This is how the payload will look like 👇. Check our Send Event API doc for more details.
Payload
...,
"data": {
    ...,
    "country": "EU"
}
If Raven is not able to find key field in the data payload of Send Event API, the condition will fail and no integration will be selected to send the notification.

Applying the Rule

Once the Integration Rule is created, you can use it in the Event while selecting the Integration/Rule for the channel. You can modify the rule by going to Integrations > Rules anytime without having to touch the Event or change anything in the API. Selecting an Integration Rule
