If you're setting up a Flow in WhatsApp API and encounter the error "100: Flow name is not unique", it means you're trying to create a Flow with a name that already exists in your WhatsApp Business Account. Since Flow names must be unique within an account, you need to resolve this issue before proceeding.

Causes of the Error

  1. Duplicate Flow Name – You’re using a name that’s already assigned to another Flow in your account.

  2. Wrong Account Selection – You might be attempting to create a Flow in the wrong WhatsApp Business Account.

  3. Previously Deleted Flow Name Conflict – Sometimes, a deleted Flow's name might still be in use within the system.

How to Fix It?

1. Check for Existing Flows

Before creating a new Flow, check if a Flow with the same name already exists.

  • Go to Meta Business Manager → WhatsApp Manager → Flows.

  • Look through the list to see if the name is already in use.

2. Rename the Flow

If the name is taken, modify it.

3. Verify the Correct Account

Ensure you are working on the correct WhatsApp Business Account. Cross-check your Business Account ID in the Meta Business Manager. Confirm that the Flow you’re creating belongs to the intended account.

4. Try a Hard Refresh

If you've deleted a Flow and still see the error:

  • Clear your cache or try accessing WhatsApp Manager from an incognito window.

  • Wait a few minutes and attempt to create the Flow again.

5. Contact WhatsApp Business Support

If the issue persists despite renaming and verifying your account, reach out to Meta Support for assistance.

By following these steps, you can quickly resolve the "Flow Name is Not Unique" error and ensure smooth workflow automation in WhatsApp API. For more troubleshooting tips related to WhatsApp API check out heltar.com/blogs.
