Hosting type Change

Preparation Checklist

1. Number Registration and Hosting

   Confirm that the phone number is registered and using On-premise hosting. If the number is unregistered, re-register it before initiating the hosting type change.

   The hosting type change does not require re-registration (OTP), but if triggered on a disconnected number, the process will fail

2. Access to 360dialog Hub

   The migration is managed through the 360dialog Hub. You must be either a Direct Client of 360dialog or work with a Partner that has Cloud API enabled. Login to the 360dialog Hub and to ensure you can trigger the migration.

3. API Key Readiness

   In Cloud, only the most recent API Key will remain valid.

4. Downtime Preparation The migration process can take between 5 and 60 minutes.

   Plan for downtime during this period.

5. No reversal When you migrate to Cloud API it is not possible to migrate back to On-Premise.

How to migrate to Cloud API

1

You can verify that the number is on Cloud API by checking the Hosting Platform Type in the Details page. It will display as Cloud API hosted by Meta.

Downtime

The migration process can take between 5 and 60 minutes, and you should expect downtime during and immediately after the migration. If you experience any issues, please contact the 360dialog Support Team.

Post-Migration

After the migration:

• Ensure you are calling the correct endpoint: https://waba-v2.360dialog.io/messages

• Use the most recently generated API Key, as old keys will not work with Cloud API. We recommend that you generate a new API Key after migration. See Cloud API Authorization Errors for more information.

• See our specific documentation for setting up the phone number webhook.

Bulk migration to Cloud API

If you need to change the hosting type for more than 50 numbers at once, please contact your Integration Partner / ISV. We will coordinate with your Partner to facilitate the migration process.
