Frequently asked questions

Bannerbear processes images asynchronously. When Ceven triggers a creation request, Bannerbear returns an initial response with an ID and a status of processing. The Ceven agent does not just stop there. It enters a polling loop, checking the status of that specific ID every few seconds until the status changes to succeeded. Once the final image URL is available, the agent captures that link and passes it to the next step in your workflow, such as posting to Twitter or saving to Dropbox. This ensures your workflow never attempts to use a broken or empty image link before the rendering engine has finished the job.
Yes. You must first upload your custom font files directly through the Bannerbear dashboard. Once the font is uploaded and approved in your account, Ceven can access it. Use the Get Available Fonts action to verify that your custom font is listed and active. When the agent generates an image, it specifies the font name exactly as it appears in the account settings. If the font name is misspelled or not yet processed by Bannerbear, the system will revert to a default sans serif font, so always verify the font list before automating a large batch of images.
Bannerbear enforces strict rate limits based on your subscription tier. If Ceven receives a 429 Too Many Requests error, the agent is designed to pause and implement an exponential backoff strategy. It will wait for a short period and then retry the request. However, if you are running a massive batch of thousands of images, you might exceed the total monthly quota. In this case, the agent will stop the workflow and send you a notification via your chosen alert channel. You can then upgrade your Bannerbear plan and resume the workflow from the last failed item.
The PDF joiner requires a list of publicly accessible URLs pointing to the PDF files you want to combine. Ceven first ensures all your individual report pages are generated as PDFs and hosted on a reachable server. The agent then compiles these URLs into an array and sends them to the Bannerbear join endpoint. Bannerbear merges the files into a single document and returns a new URL for the combined PDF. Ceven then takes this final link and can either upload it to a cloud storage provider or attach it directly to an email for your client.
Yes, but video generation takes significantly longer than image generation. While an image might be ready in seconds, a video can take several minutes depending on the length and complexity of the template. Ceven manages this by treating video requests as long running tasks. The agent triggers the video creation and then monitors the status via the List Videos or Get Video actions. Because videos consume more credits and time, we recommend using a queue system in your workflow to prevent hitting concurrency limits that Bannerbear imposes on simultaneous video renders.
Ceven does not store the actual image files on its own servers. Instead, it stores the metadata and the URL provided by Bannerbear. Bannerbear hosts the images on their own content delivery network. This means that if you delete an image within the Bannerbear dashboard, the link stored in your Ceven workflow history will eventually break. If you need permanent archives of your generated assets, we recommend adding a step to your workflow that downloads the image from Bannerbear and uploads it to your own S3 bucket or Google Drive immediately after creation.
While Ceven can update existing templates using the Update Template action, it is highly recommended that you design your base templates in the Bannerbear visual editor first. Designing a complex layout purely through API calls is difficult because you have to manually define X and Y coordinates for every element. The most efficient workflow is to create a beautiful template in the dashboard, name your layers clearly, and then use Ceven to swap out the text and images in those layers dynamically based on your data.
Signed bases allow you to generate images without exposing your private API key in the URL. Normally, a public URL could be manipulated by anyone to change the text on your images. By using signed bases, Bannerbear creates a secure hash that validates the request. Ceven can retrieve these signed bases and use them to construct URLs that are safe to embed in emails or public websites. This ensures that only the data you intended to be there is rendered, preventing third parties from using your account to generate unauthorized content.
