Q. How can I reply to clients on my mobile phone?
You can use Mobile Browser for same.
You can not use your existing WhatsApp number on the WhatsApp Cloud API. You will either have to delete your existing WhatsApp account and then you can use the same number in the WhatsApp Cloud API or you need to get a totally separate number for the WhatsApp Cloud API account.
We recommend you get a new number for the WhatsApp Cloud API.
You can refer to the link below to delete the phone number from your business account.

Here is the difference between 360Dialog & WhatsApp cloud API, here is a table for your reference:
In summary, with 360dialog, the client has access to different WhatsApp offers (Cloud API, Business API, on-premise), hosting and performance upgrades (Premium Package, local hosting, multicores), and different support levels and SLAs - none of which is offered by Meta directly.
If you are using WhatsApp cloud API, it’s a little cheaper. You can get started easily with the test phone number & free 1000 session messages.
You can make your own decision based on the information above.
Currently, you can only connect a business account to one of OCP workspaces. If you need to switch to a different workspace, you need to disconnect and reconnect again to the new workspace.
If all other CUFs are filled properly and you are still facing a parameter invalid issue, then please make sure that the phone number of the user is properly formatted. Wrong formats (number without country code, number with local code etc) usually results in an invalid parameter issue.
