If you use it instead of basic HTTP link, It will work out of the box. Assure that your backend is supports it.

The backend is supports it. But I still don't know how to use it in detail. I want to run the same mutation twice or thrice in a single HTTP request. Could you give me a specific example? Thanks

The only thing you really have to do is to change HttpLink to BatchHttpLink in you ApolloClient constructor. That's all. Do not forget to install and import corresponding apollo-link-batch-http package.

But if you are using Apollo Boost, then it's not possible to add another link, so you should migrate, following instructions here:
https://www.apollographql.com/docs/react/advanced/boost-migration

Everything will work automatically. For example, if you run multiple mutations in time window of 10 ms (that's default, you can change it by batchInterval option), than you'll see one request in Network tab. Note, that there's also number of queries limitation, configured through batchMax.
