Choosing an Integration Method

DeviceAssure supports two integration methods: Client to Server (C2S) and Server to Server (S2S). Both methods use the same DeviceAssure client library to collect device data - the difference is in how that data reaches the DeviceAssure API for validation.

Comparison

Client to Server Server to Server
How it works Library sends data directly to DeviceAssure API Library collects data; your server sends it to DeviceAssure API
Licence key location Client-side (in the library configuration) Server-side only
Implementation effort Lower - fewer moving parts Higher - requires server-side API call
Response time Optimal - direct to nearest endpoint Additional hop via your server
Server-side control Results via optional callback URL Full control over request timing and handling
Best for Most integrations, especially getting started quickly When server-side control or licence key security is required

When to Use Client to Server

Choose Client to Server if:

  • You want the simplest integration with the fewest steps
  • You don't need server-side control over validation requests
  • You want minimal latency with no extra network hops
  • You're building a straightforward web page or Android app

This is the recommended starting point for most integrations.

When to Use Server to Server

Choose Server to Server if:

  • You need to keep your licence key on the server rather than exposing it client-side
  • You want to integrate validation into existing server-side workflows
  • You need full control over when and how validation requests are made
  • Your architecture requires the client device to communicate only with your own servers

If You're Unsure

Start with Client to Server. It's simpler to implement and you can always switch to Server to Server later. The client-side library code is nearly identical for both methods - the main difference is a single configuration flag and adding a server-side API call for S2S.
