Capability checking

To understand the level of RCS capabilities of a device, it may be necessary to perform a capability check.

By identifying the RCS features a device does or doesn't support, it allows you to tailor messages to the capabilities of the user's device, or choose to communicate with them using a different channel.

When sending a message to a user via the Sinch RCS, an inline capability check is always performed, enabling appropriate fallback conditions to be used.

It's also possible to perform a standalone capability check using the capabilities endpoint

{
   "ref_id":"017b0734-b832-01df-8757-f5886b7d55e5",
   "error":"Capability lookup not allowed",
   "error_code":1018,
   "field_errors":[
      {
         "field":"",
         "errors":[
            "Capability lookup not allowed"
         ]
      }
   ]
}
