Quick setup checklist
Use this checklist to replace “topics” with Messenger opt-ins and keep your flows compliant.
Meta has updated its messaging policies for Facebook Messenger to support opt-ins instead of requiring a topic to be set for every flow.
With opt-ins:
- Contacts subscribe once
- You can send future messages without repeatedly requesting permission
- Flow setup is simpler and more flexible
Important: Topics are no longer required. Opt-ins are now the recommended and supported approach.
An opt-in is a permission request that allows a contact to receive:
- Non-promotional messages
- Updates related to a specific use case
- Broadcast messages (when applicable)
Once a contact opts in:
- You do not need to request permission again for that opt-in type
- Messages can be sent in compliance with Messenger policies
Navigate to the Flows tab and open the Facebook Messenger flow you want to edit.
[CAPTURE: Show a flow opened in the editor with Messenger as the channel.]
To request an opt-in, add the Request Opt-in action inside your flow.
- Add a new action node.
- Select Request Opt-in.
- Choose the appropriate opt-in type.
- Save the flow.
This action sends an opt-in prompt to the contact.
[CAPTURE: Show the action picker with Request Opt-in selected.]
Tip: Place the opt-in request early in the flow to avoid interruptions later.
When the opt-in is sent:
- The contact receives a Messenger prompt
- They can accept or decline
- Acceptance is stored and reused for future messages
[CAPTURE: Show the opt-in prompt as it appears inside the Facebook Messenger app.]
Once a contact has opted in:
- You can use the opt-in to send broadcast messages
- No additional consent is required for that opt-in type
This makes opt-ins ideal for:
- Updates
- Notifications
- Ongoing Messenger communication
You can also:
- Configure opt-out behavior
- Respect Messenger unsubscribe actions
- Combine opt-ins with triggers and campaigns
Note: Opt-ins are managed at the platform level and apply across flows.
Common use cases include:
- Subscription-based updates
- Ongoing service notifications
- Messenger broadcasts
- Reducing repeated permission prompts
Common Issues
I don’t see the “Request Opt-in” action
Cause: Your workspace or channel setup may not support Messenger opt-ins, or you are editing a non-Messenger flow.
Fix: Confirm the flow is using the Facebook Messenger channel, then reload the editor and check the action list again.
The contact didn’t receive the opt-in prompt
Cause: The contact did not reach the Request Opt-in action, or the flow path bypasses the opt-in step.
Fix: Review your flow logic and ensure the contact reaches the node containing Request Opt-in.
The contact declined the opt-in
Cause: The contact chose not to subscribe to that opt-in type.
Fix: Continue the flow with an alternate path (for example, a short explanation and a non-subscription option), or request the opt-in later if appropriate.
Broadcast messages still fail for some contacts
Cause: Those contacts may not have accepted the required opt-in type, or they opted out after subscribing.
Fix: Ensure your broadcast uses the correct opt-in type and verify that the audience has opted in to that type.
