With the Oauth2 module you can safely send data from and to Deploy. This module is separated in a server component (External system to Deploy) and a client (Deploy to an External system).
Server
If you want to send (customer)data to a Deploy Webhook or retrieve inbox messages from the Mobile Messages API, you can use the Oauth2 module to setup a secure connection. See more information in our manual: Oauth 2.0 Server for Deployteq webhooks.
Clients
You can use the clients component if you want to send information to a external system, for instance with the HTTP request object within a campaign or the Pega App based on a client credentials flow.
Costs
This module is free of charge.
