Newscred

Newscred is the content marketing platform company that began as a licensed-content syndication API and grew into an enterprise Content Marketing Platform (CMP), Marketing Resource Management and Digital Asset Management suite. The company rebranded to Welcome in 2020 after Industry Dive acquired its content-services business, and Optimizely acquired Welcome in December 2021, where the product now ships as Optimizely Content Marketing Platform. The API lineage is continuous and the vendor documents it: the Open API base URL moved from https://api.newscred.com/v3 to https://api.welcomesoftware.com/v3 (28 March 2021) to https://api.cmp.optimizely.com/v3, and CMP still requires customers to allowlist *.newscred.com. The public contract is a 170-operation OAuth 2.0 REST API published by the newscred GitHub organization, covering library and digital asset management, tasks and workflows, campaigns, publishing, structured content, work requests, templates, teams and settings, plus a webhook event surface.

Newscred publishes 19 APIs on the APIs.io network, including Assets API, Brand Compliance API, Campaigns API, and 16 more. Tagged areas include Company, Content Marketing, Content Management, Digital Asset Management, and Marketing.

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

Newscred’s developer surface includes documentation, API reference, getting-started guide, authentication, support, engineering blog, pricing, and 30 more developer resources.

  description: 'Facilitates the integration of external systems with Optimizely CMP through the following use cases:

    1. **External Work Management** – Use the endpoints to link Optimizely CMP with an external system (such as Jira or Aha).
    The external system can send status updates back to Optimizely CMP so that the Optimizely CMP user receives in-app updates
    for the status of the ''ticket'' in the external system.

    2. **External Document Approval** – (a.k.a. Marketing Legal Review) Use the endpoints to link Optimizely CMP with an external
    system (such as Veeva PromoMats) to review, annotate, update, and approve marketing assets through the external system.
    The approval status can be sent back to Optimizely CMP so that the Optimizely CMP user receives in-app updates for the
    final approval status of the documents from the external system.

    For information on these use cases, contact Optimizely CMP Support.'
