Zoho Campaigns

Zoho Campaigns is Zoho Corporation's email marketing platform, and it exposes two distinct public API surfaces. The Zoho Campaigns API v1.1 is an RPC-over-HTTP interface for campaigns, mailing lists, contacts, segments, custom fields, merge tags, coupons, topics and automation workflows, authenticated with OAuth 2.0 against Zoho Accounts and returning JSON or XML selected with a resfmt query parameter. The Zoho Campaigns Email API v2 is a separate resource-oriented JSON REST API for transactional and bulk sending — transmissions, stored templates, recipient lists, suppression lists, sending and tracking domains, users, licensing, delivery reports and event webhooks — authenticated with an API key. Zoho publishes no OpenAPI for either surface; the machine-readable contract it does publish is a first-party Postman collection for the Email API.

Zoho Campaigns publishes 1 API on the APIs.io network: Email API. Tagged areas include Email Marketing, Campaigns, Mailing Lists, Subscribers, and Email Templates.

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

Zoho Campaigns’ developer surface includes documentation, API reference, quickstart, support, engineering blog, pricing, signup flow, and 33 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Telecommunications regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/zoho-campaigns: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you?
