Marin API

name: Marin API
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.
