Frequently asked questions

Countdown API only retains result set summaries and metadata for 14 days. Ceven manages this by automatically triggering the Get Result Set action as soon as a collection run completes. The agent then moves the actual data payload into your preferred long term storage, such as a database or a cloud drive, before the 14 day window expires. This ensures you have a permanent historical record of eBay price movements and seller performance without worrying about the platform deleting the source files. You can configure the agent to archive these daily or weekly depending on your volume.
Yes. Ceven uses the Create Collection and Update Collection actions to define when and how often eBay data is pulled. You can set up a workflow where the agent monitors a list of keywords and creates a new collection every morning at 8 AM. Once the collection is active, Ceven polls for the completion status and then triggers the export flow. This removes the need for you to manually log into the dashboard to start runs or check if the data has arrived, making the entire market intelligence loop hands free.
If your destination server is down or returns an error, the result set notification might be missed. Ceven monitors the status of your result sets and can be configured to detect missing deliveries. When a failure is identified, the agent uses the Resend Result Set Webhook action to force Countdown API to push the data again. This ensures that your internal systems stay in sync with eBay marketplace changes even during temporary network outages or server maintenance windows on your end.
The eBay Autocomplete action allows Ceven to see exactly what users are typing into the eBay search bar in real time. You can build a workflow that takes a seed keyword, pulls all autocomplete suggestions, and then feeds those suggestions into a new collection to analyze search volume and competitor density. This is highly effective for finding long tail keywords that have high intent but lower competition, allowing you to optimize your product titles and descriptions based on actual user behavior on the marketplace.
Yes. Countdown API has specific tier gating based on your subscription plan which limits the number of concurrent collections and the total volume of requests you can queue. If you attempt to create a collection that exceeds your plan limit, the API will return an error. Ceven handles this by first calling the Get Account Information action to check your remaining quota. If the quota is too low, the agent will alert you or queue the request for a later time when your credits reset, preventing workflow crashes.
While the raw API response is JSON, Countdown API provides a specific Export Requests CSV tool. Ceven leverages this to generate direct download links for your data. You can set up a workflow that takes these CSV links and automatically uploads them to a Google Sheet or a SharePoint folder. This is ideal for teams that need to share eBay market reports with non technical stakeholders who prefer spreadsheets over raw data feeds or custom dashboards.
Ceven uses the Create Destination and Update Destination actions to manage where your data lands. You can configure multiple endpoints, such as a production database for real time pricing and a backup S3 bucket for archival. The agent can route specific collections to specific destinations based on the data type. For example, seller feedback collections can go to a sentiment analysis tool while product price collections go directly to your pricing engine, ensuring the right data reaches the right system without manual sorting.
Yes. To keep your workspace organized, Ceven can be programmed to perform maintenance. It uses the List Collections action to identify collections that have not been run in thirty days and then calls the Delete Collection action to remove them. It can also use Clear Collection Requests to empty the queue of an idle collection before archiving it. This prevents your account from becoming cluttered with outdated search parameters and ensures that your active monitoring projects remain easy to find and manage.
