Streak

Streak is a CRM that lives inside Gmail, turning the inbox into a pipeline management workspace for sales, hiring, support, fundraising, deal flow, and project tracking using pipelines, boxes, stages, and email tracking. The Streak API provides programmatic REST access to the core CRM data models including pipelines, boxes, stages, fields, threads, tasks, and teams. Authentication uses HTTP Basic Auth with the API key as the username.

Streak publishes 7 APIs on the APIs.io network, including Boxes API, Fields API, Newsfeed API, and 4 more. Tagged areas include CRM, Sales, Gmail, Pipeline Management, and Email Tracking.

Streak’s developer surface includes authentication, documentation, pricing, signup flow, support, engineering blog, and 7 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/streak: open an issue to ask a question, or submit a pull request to add artifacts.
