In my app people can send a text message to whoever they want.
However, when they have already texted a certain number before, they can not text that number again.
Yet, other users are still able to text that number.
Basically, I need a workflow that triggers only when ‘Current user’s phone numbers is not yet used’. And if they have already texted that person, an alert has to remind them of it.
How do I create such a workflow? I’ve read a few other topics about making sure that users have a unique username. Yet I’m still not able to figure this out.
Hopefully you, yes you who is reading this post right now ;-), can help me with this little workflow.
Thanks in advance!
