Third-Party SMS Provider
Sinch Contact Pro integrates out of the box to two SMS and two social channels providers. If you use one that is not listed as a supported provider, integration work is required. In practice, you need to build middleware or a proxy that speaks the supported protocol to Sinch Contact Pro and provider's protocol to the provider.
It is recommended to use:
- Sinch SMS interface or Sinch Conversation API for SMS integration
- Sinch Conversation API for social channels
