I'd highly recommend using Transifex. https://www.transifex.com. They have many integrations and their API is pretty solid. You can easily hook Transifex into your build pipeline. As an example at my place of work we've got it set up so that on master merges when the test are running on CircleCI all source (English) strings are pushed to Transifex.

Once all necessary strings are pushed to Transifex, you place your order.

In addition all of the above Transifex also has "Transifex Live". Which allows you to detect/translate strings live. Though this involves including their Transifex script tag in the head of your page.
