Marin Software

Marin Software is a performance marketing and digital advertising management platform used by e-commerce brands, agencies, and enterprise marketers to plan, automate, and optimize paid media at scale across paid search, paid social, retail media, and app advertising channels. Its product line includes MarinOne (campaign management and automation), Marin Connect (marketing data collection and unification), Marin Ascend (cross-channel optimization), Marin for Agencies, and managed services. Marin publishes a POST-only REST write API — the Marin API, at https://api.marinsoftware.com/open-api version 0.1 — that pushes campaigns, groups, keywords, ads and strategies into the platform using HTTP Basic auth, documented only in the help center, plus a Marin Social API whose reference link no longer resolves. There is no OpenAPI, no SDK, no changelog and no status page, and the developer documentation portal has been decommissioned. Marin Software has been acquired by Zax Capital, which the company announces on its own homepage.

Marin Software publishes 1 API on the APIs.io network. Tagged areas include Company, MarTech, Advertising, Marketing, and Performance Marketing.

Marin Software’s developer surface includes pricing, engineering blog, signup flow, documentation, API reference, support, authentication, and 16 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

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/marin-software: open an issue to ask a question, or submit a pull request to add artifacts.

  description: A POST-only REST API for programmatically writing data into Marin. Five bulk endpoints — /campaigns, /groups,
    /keywords, /ads and /strategies — accept a JSON body containing a single "data" array of rows whose keys are the same
    column headers used by Marin's bulk-upload spreadsheets. Requests are HTTPS only, authenticated with HTTP Basic using
    a MarinOne username and password issued by a Marin representative, and scoped by four required query-string parameters
    (clientId, customerId, userId, userCustomerId) read out of the MarinOne UI. The API is versioned in the URI path; only
    version 0.1 is published. Marin publishes no OpenAPI, no SDK and no error catalog beyond HTTP 200 and 500.
