Marin API is published by [Marin Software](https://apis.io/providers/marin-software/) on the [APIs.io](https://apis.io/) network.

The published artifact set on APIs.io includes API documentation, an API reference, authentication docs, and rate-limit docs.

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.
