Hiver

Hiver (Hiver Inc., originally GrexIt) builds an AI-powered customer service platform for teams that run support out of shared email addresses. It ships in two forms: Hiver in Gmail, a Chrome-extension helpdesk that turns shared inboxes like support@ and billing@ into assignable, SLA-tracked queues without leaving Gmail; and Hiver Omni, a standalone omnichannel platform covering email, live chat, Slack, voice, WhatsApp, a help center and a customer portal. Hiver publishes a public REST API for Shared Inboxes, conversations, users, tags and internal notes, documented on a Theneo developer portal with a downloadable OpenAPI 3.0.2 contract, and gates API access to its Pro plan and above.

Hiver publishes 2 APIs on the APIs.io network: Conversations API and Inbox API. Tagged areas include Company, Customer Service, Help Desk, Shared Inbox, and Email.

The Hiver catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Hiver’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, changelog, pricing, and 24 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/hiver: open an issue to ask a question, or submit a pull request to add artifacts.
