Frequently asked questions

Ceven monitors your credit balance by calling the remaining quota endpoint before initiating any heavy generation tasks. If a workflow is set to generate a high volume of videos, the agent can be configured to pause and send a Slack notification to the admin when credits drop below a certain threshold. This prevents critical automation failures where a lead might not receive a video because the account ran out of credits. You can also set up a workflow that alerts you when quota usage spikes unexpectedly, allowing you to upgrade your plan before the API returns a credit exhausted error during a live campaign.
Yes. You can build a workflow where Ceven listens for a new video asset being added to your HeyGen library. Once the event fires, the agent can automatically trigger translation requests for a predefined list of target languages. It will then poll the translation status endpoint until the processed videos are ready. Once complete, the agent can move those translated files into specific folders or push the links to your localized marketing channels. This removes the need to manually request translations for every single piece of content you produce for global markets.
Ceven manages the technical handshake required for real time interactions. The agent first creates a streaming token with a specific expiry time to ensure secure access. It then initiates the session and can send tasks to the avatar to make it speak specific text in real time. Because these sessions rely on WebRTC, Ceven handles the signaling and can interrupt the session if the user triggers a stop command or if the interaction window closes. This allows you to build AI receptionists or interactive guides that respond to user inputs dynamically without manual intervention.
Talking photos require a high quality binary image to produce a natural result. A common quirk in the HeyGen API is that images with complex backgrounds or non frontal faces often result in distorted animations. Ceven can help by adding a validation step where the agent checks the image metadata or uses a vision model to ensure the face is centered before sending it to HeyGen. If the image does not meet the requirements, the agent can flag it for a human to review instead of wasting credits on a poor quality render that would need to be deleted.
Absolutely. Ceven can access both public and private avatars associated with your account. When you list avatars, the agent identifies your custom trained avatars by their unique IDs. You can then specify in your workflow that all personalized sales videos should use a specific executive avatar while internal training videos use a different corporate avatar. This allows you to maintain brand consistency across different automation paths while leveraging the high fidelity of your own custom digital twins for a more personal touch with your customers.
The agent uses the generate video template endpoint to inject dynamic data into pre designed layouts. Instead of creating a video from scratch, you design a template in HeyGen with placeholders for names, dates, or company logos. Ceven pulls the actual values from your data source, such as a Google Sheet or HubSpot, and maps them to the template variables. This ensures the visual quality remains professional while the content is uniquely tailored to every single recipient, making it ideal for scaleable personalized video marketing campaigns.
Yes, AI video generation is an asynchronous process. When Ceven requests a video, HeyGen returns a job ID rather than the final file. The agent then enters a polling loop, checking the video status endpoint at regular intervals. Depending on the length of the video and the current server load, this can take from a few seconds to several minutes. Ceven handles this waiting period silently and only triggers the next step in your workflow, such as sending an email, once the status changes to completed and a final URL is provided.
Ceven uses secure API connections to transmit your data to HeyGen. We do not store your raw video scripts or uploaded images on our own servers longer than is necessary to execute the workflow. All communication happens over encrypted channels. Because you control the API permissions, you can ensure the agent only has access to the specific assets and folders required for the task. You can also set up a cleanup workflow that uses the delete video endpoint to remove temporary assets from the HeyGen cloud once they have been delivered to the end user.
