Frequently asked questions

Ceven includes a built in queuing system that respects Klaviyo API thresholds. For example, the campaign creation endpoint has a steady limit of 150 requests per minute. When a workflow triggers a bulk operation, Ceven buffers the requests and drips them into Klaviyo at a pace that prevents 429 errors. If the agent hits a burst limit, it implements an exponential backoff strategy to retry the operation without failing the entire workflow. This ensures that your marketing automation stays active even during high volume events like Black Friday where API calls typically spike.
Yes. The integration covers the full suite of Klaviyo messaging. The agent can add profiles to lists that are tagged for both channels, create SMS specific campaigns, and update phone number attributes on profiles. When you use the create campaign action, you can specify the channel you want to target. The agent also manages the consent flags required for SMS compliance, ensuring that you only send messages to users who have the correct subscription status for that specific communication channel.
Ceven is subject to the same account limits as the Klaviyo dashboard. Specifically, Klaviyo enforces a hard limit of 1000 templates per account. If your account reaches this cap, any attempt by the agent to use the create template or create template clone actions will result in an error. We recommend using the agent to clean up old or unused templates periodically to make room for new designs. The agent can list your templates and identify those that have not been used in a campaign for several months.
Ceven uses the create event endpoint to push behavioral data into Klaviyo. You provide a metric name and the profile identifier. For instance, if a customer completes a specific training module in your app, Ceven sends an event called Completed Module. This event then appears in the customer profile and can be used as a trigger for a Klaviyo flow. This allows you to move beyond simple purchase data and trigger emails based on actual product usage or engagement milestones happening outside of the store.
Yes, the agent can utilize bulk create event endpoints to process up to 1000 events per request. This is significantly more efficient than processing profiles one by one. When you ask the agent to sync a large dataset, it automatically batches the records into the maximum allowed payload size of 5MB. This prevents timeout issues and reduces the number of API calls made to Klaviyo, which helps you stay well within your rate limits while ensuring your marketing data is current.
Ceven can automate the entire coupon lifecycle. First, it uses the create coupon action to define the discount percentage and expiration date. Then, it uses the create coupon code action to generate a unique string for a specific customer. This code is returned to the workflow, where the agent can then embed it into a personalized email or send it via SMS. This removes the need to manually generate codes or use a third party app to bridge the gap between your CRM and Klaviyo.
Ceven uses the create or update profile action which relies on a unique identifier, typically an email address or a phone number. If the identifier already exists in your Klaviyo account, the agent simply updates the existing profile with the new attributes provided. If the identifier is not found, Klaviyo creates a new profile. This ensures that you maintain a single source of truth for every customer and prevents the creation of duplicate records when users change their names or update their preferences.
Yes, using the create template render action, the agent can take a template ID and a set of profile attributes to generate a preview of how the email will look for a specific user. The agent receives the final HTML or plain text version of the email. This is particularly useful for quality assurance workflows where you want the agent to check if dynamic tags are populating correctly before a campaign is scheduled for a large segment of your audience.
