How to get feasibility estimates for a launched target group
During the fielding of a survey, conditions (like respondent availability or supplier performance) can change. A feasibility request on an already launched or active target group allows you to check current audience availability and estimated costs based on your defined criteria, helping you to refine your project plan and budget in real-time.
This guide applies only to target groups in a non-draft status (e.g., launched, active, paused, completed). If you need to create a target group in draft status, you can refer to our guide on how to create a target group in draft status.
Information is based on the current state of the target group. The request properties are all optional. They serve as a way of performing what-if analysis.
Before you can get the feasibility for an existing target group, you'll need to have:
- Your unique account ID:
{account_id}path parameter - Your project ID:
{project_id}path parameter - Your target group ID:
{target_group_id}path parameter - Your API authentication token (JWT):
<YOUR_JWT_TOKEN>
For a deeper understanding of how our feasibility calculations work, you can refer to our guide on how Cint's feasibility works.
See the feasibility API reference documentation for further references.
Fields passed in the request body override the existing target group settings for the purpose of the feasibility calculation only. The actual target group settings will remain unchanged.
Step 1: Prepare your feasibility request body
First, you'll construct the JSON payload that defines the parameters for your feasibility query. This includes details like your desired locale, expected incidence rate, defined profile, and completes goal, along with pricing information.
For the direct cURL examples, skip to Step 2: Make the feasibility request.
Fields to consider:
locale(string, optional): The target locale (e.g., "eng_us"). See our list of supported locales for all valid codes.collects_pii(boolean, optional): You should set this totrueif your survey collects personally identifiable information, andfalseotherwise.expected_incidence_rate(number, optional): Your expected survey incidence rate (IR) as a decimal (e.g., 0.5 for 50%).expected_length_of_interview_minutes(number, optional): Your estimated length of interview (LOI) in minutes (e.g., 20).completes_goal(number, optional): Your desired number of completes (e.g., 40).fielding_specification(object, optional): This defines the fieldwork start and end dates.start_at(string, optional): The start date and time of fieldwork in RFC3339 UTC format.end_at(string, optional): The end date and time of fieldwork in RFC3339 UTC format.
price(object, conditionally optional): The proposed cost per interview. This is specific to business units associated with the dynamic pricing model. Find out more about feasibility for dynamic pricing here. Parameter is ignored if using rate card pricing model.value(string, optional): The monetary value.currency_code(string, optional): The ISO 4217 currency code (e.g., "USD").
rate_card_price_boost(object, conditionally optional): An optional amount to add to your rate card price. This is specific to business units associated with rate card pricing model. Find out more about feasibility for rate card pricing here*. Parameter is ignored if using dynamic pricing model.value(string, optional): The monetary value.currency_code(string, optional): The ISO 4217 currency code.
profiling(object, optional): This contains an array defining the demographic and behavioral targeting criteria. This matches the profile used when creating a target group. An empty array ([]) means no specific profile targeting beyond the locale. You can refer to the Cint profile question library for valid profile questions and options.profile_adjustment_type(string, optional): The method for adjusting the profile. Valid values arepercentageorcpi_based.profiles(array of objects, optional): An array of profile objects defining your targeting criteria.object(string, required): The profile object type. For regular profiles, useregular.quotas_enabled(boolean, required): Set totrueto enable quotas for this profile.targets(array of objects, required): An array of target objects defining specific targeting conditions and quotas.conditions(array of objects, required): An array of condition objects that specify the targeting criteria.object(string, required): The condition object type. For range conditions, userange.question_id(integer, required): The unique identifier for the profiling question.min(integer, required): The minimum value for the range condition.max(integer, required): The maximum value for the range condition.
quota(object, optional): The quota settings for this target.- For percentage-based quotas:
completes_goal_percentage(integer, required): The percentage of the total completes goal allocated to this target (e.g., 50 for 50%).
- For absolute quotas:
completes_goal(integer, required): The absolute number of completes allocated to this target (e.g., 250).
- For percentage-based quotas:
allocations(object, optional): Allows you to specify allocations for different supplier sources. If omitted, the system will use default allocation settings.open_exchange_allocations(object, optional): Defines allocations for the Open Exchange supply source.min_completes(integer, optional): The minimum number of completes to allocate from Open Exchange.max_completes(integer, optional): The maximum number of completes to allocate from Open Exchange.groups(array of objects, optional): An array of group allocation objects for more granular control.group_id(string, required): The unique identifier for the supply group.min_completes(integer, required): The minimum number of completes to allocate from this group.max_completes(integer, required): The maximum number of completes to allocate from this group.
Step 2: Make the feasibility request
Next, you'll send your prepared request body to the feasibility endpoint.
- API endpoint:
POST https://api.cint.com/v1/demand/accounts/{account_id}/projects/{project_id}/target-groups/{target_group_id}/calculate-feasibility
Reminder, you will need the following to make the request:
- Your unique account ID:
{account_id}path parameter - Your project ID:
{project_id}path parameter - Your target group ID:
{target_group_id}path parameter - Your API authentication token (JWT):
<YOUR_JWT_TOKEN> - Cint API Version:
2025-12-18
Example cURL request
- Rate card pricing
- Dynamic pricing
You want to see the feasibility impact if you were to increase the CPI by $2.00 USD.
Scenario: The target group (target_group_id) has no rate_card_price_boost (rate_card_price_boost = $0.00). This feasibility request will show the impact of adding a $2.00 USD boost to the current CPI.
curl -L 'https://api.cint.com/v1/demand/accounts/{account_id}/projects/{project_id}/target-groups/{target_group_id}/calculate-feasibility' \
-H 'Content-Type: application/json' \
-H 'Accept: application/json' \
-H 'Authorization: Bearer <YOUR_JWT_TOKEN>' \
-H 'Cint-API-Version: 2025-12-18' \
-d '{
"rate_card_price_boost": {
"value": "2.00",
"currency_code": "USD"
}
}'
You want to see the feasibility impact if you were to increase the CPI by $2.00 USD.
Scenario: The target group (target_group_id) has a CPI value of $1.00 (target_group_cpi = $1.00). This feasibility request will show the impact of adding a $2.00 USD boost to the CPI.
curl -L 'https://api.cint.com/v1/demand/accounts/{account_id}/projects/{project_id}/target-groups/{target_group_id}/calculate-feasibility' \
-H 'Content-Type: application/json' \
-H 'Accept: application/json' \
-H 'Authorization: Bearer <YOUR_JWT_TOKEN>' \
-H 'Cint-API-Version: 2025-12-18' \
-d '{
"price": {
"value": "2.00",
"currency_code": "USD"
}
}'
Remember to replace all bracketed placeholders (e.g., <YOUR_JWT_TOKEN>) with your actual values.
Step 3: Interpret the feasibility response
A successful request will return an HTTP 200 OK status code and a JSON object containing the feasibility estimate.
Example successful response
Response values will depend on your target group settings and any overrides you provided in the request body.

Troubleshooting common issues
HTTP 400 Bad Request:- Check that all required fields in the request body are present and correctly formatted (e.g., dates are RFC3339 UTC).
- Make sure your
expected_incidence_rateis between 0.01 and 1.00. - Verify that the
localeis valid and supported.
HTTP 401 Unauthorized: Your JWT token is missing or invalid. You can refer to our authentication guide for more information.HTTP 403 Forbidden: Your JWT token is valid, but it doesn’t have the necessary permissions for this operation.HTTP 404 Not Found: Theaccount_idin the URL path is incorrect or doesn’t exist.- Unrealistic feasibility results (e.g., 0 completes):
- Review your
profilesarray. Are the question IDs and options valid? Are the quotas realistic for the target demographic? - Check your
expected_incidence_rateandexpected_length_of_interview_minutes. Very low IRs or very long LOIs can severely impact feasibility. - Make sure your
start_atandend_atdates define a sufficient fielding window.
- Review your
- Placeholders: Make sure you've replaced all placeholder values (e.g.,
{accountId}) with your actual data before making the request.
