Chat platform APIs and SDKs allow a company to integrate existing real-time chat solutions into its own websites and applications. You can think of both APIs and SDKs as prebuilt solutions. Both abstract away all the complexities of messaging software, enabling businesses to provide first-class chat capabilities without reinventing the wheel. This off-loads the burden of implementation to the provider.
