AddedConfigurable duration for respondent activity exclusions

27 April 2026

The respondent activity exclusions duration is now configurable. You can specify how far back exclusion checks should look using a new duration field in ISO-8601 period format (date-based only, e.g. P30D, P2W, P3M, P1Y). Allowed values are between 1 and 396 days. If no duration is provided, the window defaults to P90D (90 days), preserving the previous behavior.

AddedRespondent activity exclusions

20 April 2026

You can now exclude respondents from entering a target group based on their participation history in other projects or target groups. Exclusions are evaluated dynamically at the moment a respondent attempts to enter a survey, enabling real-time overlap prevention for concurrent live studies.

Key capabilities:

  • Unified API workflow: Pass an array of project and target group IDs in a single request to define multi-layered exclusions.
  • Real-time enforcement: Exclusion checks happen at the point of entry, keeping your sample accurate for live studies.
  • Automated 90-day window: Respondents with a Completed or In-client status in any excluded project or target group are automatically excluded for 90 days. Duration is not currently configurable.

New endpoints:

Updated endpoints:

Our configurable exclusions period will be out soon, which will allow you to make edits to the respondent activity exclusions duration period.

AddedPrivate exchange CPI added to target-group-updated webhook

27 January 2026

Version: Added to releases from 2025-05-27 onwards.

BreakingNew Cint Exchange Demand API version 2025-12-18

18 December 2025

We're committed to continually enhancing the Cint Exchange Demand API to help you get to insights faster and more efficiently. Based on your feedback, the 2025-12-18 API version introduces improvements across design, structure, and performance.

Please use version 2025-12-18 to access the improvements outlined below.

New integration policy

The release of the Cint Exchange Demand API version 2025-12-18 introduces a new forward-only integration policy.

What is a forward-only integration

Once the 2025-12-18 version is used for a resource such as profiling, older API versions for the same resource will not be supported.

Why we are introducing this change

The new API version introduces advanced data structures, such as open-ended grouping, that are not compatible with legacy API versions. Updating a resource that has been created or modified using the newer version via older endpoints may lead to data inconsistencies, corruption, or integration errors. This policy helps preserve data integrity, ensures access to the full capabilities of the latest API version, and delivers a consistent, interchangeable experience.

What this means for you

If you begin using the Cint Exchange Demand API version 2025-12-18 for a specific resource, for example profiling, all subsequent create, write, or update operations for that resource must use the 2025-12-18 version of the API.

This approach ensures stability, data consistency, and long-term compatibility as the platform evolves.

How can you start integration?

Please contact your Cint integration consultant to learn more about our latest API version and how to enable access on your account.

Key changes

Profiling
New profiling features
  • Group open-ended questions. This allows multiple free-text questions to be bundled under a single group instead of completely separate items. Example: product feedback grouping two questions such as "what did you like most about the product?" and "what did you like least about the product?"
  • Apply a profile template to target group endpoints.
  • Apply a profile template combined with your own profiling setup.
  • Give quotas their own name using the name field to improve tracking.
Updated profiling features
  • Interlocked profiles are no longer a standalone object and are now part of the profiling object known as "blended profiles".
  • The target object is now the central piece that links questions, conditions, and quotas. Existing use of profiles will need to be refactored to accommodate the change.
  • Property fields have been renamed to improve clarity:
    • filling_goal → completes_goal
    • quota_percentage → completes_goal_percentage
    • quota_nominal → completes_goal
    • index → condition
    • indexes → conditions
    • ungrouped → target
    • grouped → target
    • interlocked_profiles → now specified by the ENUM value blended within profiles: []
  • Endpoints have been renamed:
    • /apply-profiles → /manage-profiles
    • /create_interlocked_profile → /create-blended-profile
    • /generate-interlocked-profile → /generate-blended-profile
    • /panel-distribution → /supplier-quota-distribution
Removed profiling endpoints

The endpoints below have been removed to accommodate the declarative profiles endpoint for launched target groups:

  • PUT https://api.cint.com/v1/demand/accounts/{account_id}/projects/{project_id}/target-groups/{target_group_id}/profiles/disable-quotas
  • GET https://api.cint.com/v1/demand/accounts/{account_id}/projects/{project_id}/target-groups/{target_group_id}/profiles
  • POST https://api.cint.com/v1/demand/accounts/{account_id}/projects/{project_id}/target-groups/{target_group_id}/profiles/:profile_id/convert-to-regular-profile
  • POST https://api.cint.com/v1/demand/accounts/{account_id}/projects/{project_id}/target-groups/{target_group_id}/profiles/:profile_id/group-quotas
Example: New profile markup
"profiles": [
  {
    "object": "regular",
    "id": "01JY5Q1GY7JWX1JHQH8D1W2N9Z",
    "name": "birth gender",
    "description": "¿Es usted…?",
    "description_translated": "What is your gender?",
    "quotas_enabled": true,
    "targets": [
      {
        "id": "01JY5V5NDSVHG8S3FX63Y73K3F",
        "text": "Hombre",
        "text_translated": "Male",
        "conditions": [
          {
            "object": "selection",
            "question_id": 43,
            "option": "1"
          }
        ],
        "quota": {
          "name": "SF-BirthGender-Quota-1",
          "completes_goal_percentage": 49.21,
          "completes_goal": 492,
          "completes": 0,
          "prescreens": 0
        }
      }
    ]
  }
]
Feasibility

Updated the feasibility endpoint to simplify calls by removing the requirement for project_id:

  • Removed: POST https://api.cint.com/v1/demand/accounts/{account_id}/projects/{project_id}/target-groups/calculate-feasibility
  • New endpoint: POST https://api.cint.com/v1/demand/accounts/{account_id}/target-groups/calculate-feasibility

The supplier_ids: [] within the allocations: {} object now matches its usage across other endpoints.

General improvements

Updated error messages clarify what went wrong to increase clarity.

Additional changes

  • human_readable_id now follows snake_case standard. Affected endpoint: GET https://api.cint.com/v1/demand/accounts/{account_id}/projects/{project_id}
  • Target group performance endpoint currency format updated to match all other endpoints: "completes_cost": {"value": "2.7352", "currency_code": "USD", "currency_scale": null}
  • client_cpi renamed to client_cost_per_interview_note to clarify it refers to a note, not the actual CPI.
  • pricing_model and type enum value ratecard changed to rate_card (snake_case). Affected endpoints:
    • https://api.cint.com/v1/demand/accounts/{account_id}/projects/{project_id}/target-groups/{target_group_id}
    • https://api.cint.com/v1/demand/accounts/{account_id}/projects/{project_id}/target-groups/{target_group_id}/overview
    • https://api.cint.com/v1/demand/accounts/{account_id}/business-units/{business_unit_id}/generate-price-prediction
