    • One place to manage, scope, and revoke 2chat access.

Frequently asked questions

Ceven implements a smart queuing system that respects the specific rate limits of your 2Chat subscription tier. If the agent detects a 429 Too Many Requests response from the 2Chat API, it automatically pauses the workflow and employs an exponential backoff strategy. This means the agent waits a few seconds before retrying, then increases the wait time if the error persists. This prevents your account from being temporarily flagged or banned by 2Chat for spamming requests. You can monitor these pauses in the workflow logs to see if you need to upgrade your 2Chat plan to support higher message volumes for your business.
Yes. You can set up a workflow where a form submission triggers the Create Contact action in 2Chat. The agent takes the name and phone number from the form, validates that the phone number is in the correct international format, and then pushes it to your 2Chat account. Once the contact is created, the agent can immediately trigger a welcome message via WhatsApp. This removes the need for manual data entry and ensures that your sales team can engage with leads the second they express interest on your website, creating a seamless transition from lead capture to active conversation.
When a 2Chat webhook fails to reach Ceven, the system logs the failure and attempts to reconcile the state during the next polling cycle if you have a fallback configured. Because 2Chat relies on these webhooks to signal new messages, a failure means the agent might not react in real time. To mitigate this, you can use the List Webhook Subscriptions tool to audit your endpoints. If you see consistent failures, the agent can help you diagnose if the issue is a timeout or a payload mismatch and suggest the correct configuration to restore the real time flow of messages.
Yes, the 2Chat API allows for group management and messaging. You can use Ceven to pull a list of group members or send announcements to an entire group. However, keep in mind that WhatsApp has strict rules regarding group spam. The agent is designed to follow these guidelines by using specific templates and ensuring that group messages are triggered by legitimate business events. If you attempt to send bulk messages to groups without proper opt in, your 2Chat account may be flagged by WhatsApp, so we recommend using the agent to manage small, high value coordination groups.
Ceven uses the Get API Usage Info tool to pull your current consumption metrics directly from 2Chat. You can build a weekly report workflow where the agent checks your remaining quotas every Friday and sends you a summary via email or Slack. If your usage spikes unexpectedly, the agent can be configured to send an urgent alert. This is particularly useful for businesses that scale their marketing efforts quickly, as it prevents a sudden outage of your WhatsApp automation by alerting you to buy more credits or upgrade your plan before you hit the hard limit.
The agent can pull your full contact list and then apply complex filters using the workflow layer. While the 2Chat API provides the raw list, Ceven can parse that data to find contacts who have not been messaged in thirty days or those who belong to a specific customer segment. You can then pass this filtered list into a loop to send personalized follow up messages. This allows you to perform targeted outreach without needing to export your contacts to a CSV file and manually upload them into a different marketing tool, keeping all your data inside the secure pipeline.
The primary limit is based on your 2Chat account tier and the API pagination limits. When Ceven calls the List Contacts tool, it handles the pagination automatically, walking through every page of results to ensure no one is missed. However, for accounts with hundreds of thousands of contacts, this process can take several minutes and may consume a significant portion of your API quota for that window. We recommend using the Search Contacts tool for specific lookups rather than listing the entire directory if you have a very large database, as this is much faster and more efficient.
Ceven uses industry standard encryption to store your 2Chat API keys. Your keys are encrypted at rest and are only decrypted in memory for the millisecond it takes to sign the request to the 2Chat servers. We never log your raw API keys in our application logs or expose them to the LLM during the prompt construction phase. Access is strictly limited to the specific actions you authorize within your workflow. You can rotate your API key in the 2Chat dashboard at any time, and simply updating the key in your Ceven settings will restore service immediately without needing to rebuild your workflows.
