If you’re working with WhatsApp API and encounter the error 2068 - Flow is blocked, it means that your flow is in a blocked state. This can occur due to various reasons, including incomplete setup of an endpoint or an issue with the public key. This guide will help you identify the causes and resolve the issue quickly.

What Causes the '2068 - Flow is Blocked' Error?

How to Fix '2068 - Flow is Blocked' Error

1. Verify Flow Status

Check if the flow is blocked due to internal restrictions:

  • Log into your WhatsApp API provider’s dashboard.

  • Navigate to the flow settings.

  • Ensure it is active and not manually disabled.

If your flow interacts with an external endpoint, ensure that:

  • The endpoint URL is correctly configured.

  • Any required authentication (such as API keys) is properly set up.

  • You have granted the necessary permissions.

3. Upload or Update Public Key

If the flow relies on encryption or authentication:

  • Check if the public key is uploaded in the API settings.

  • If the key has expired, generate and upload a new one.

  • Verify that the key format is correct.

4. Review Recent API Updates

WhatsApp may introduce changes that affect your flows. Stay updated by:

  • Checking WhatsApp’s official API documentation.

  • Reviewing change logs and release notes from your API provider.

5. Restart and Re-test the Flow

Once you have made the necessary fixes restart the flow and test with sample requests to ensure it works correctly.
