How to get feasibility estimates for the target group you would like to launch
Feasibility requests let you simulate a target group launch based on your targeting criteria. This provides insights into your potential audience reach and costs to help you refine your project plan and budget.
Before you can get the feasibility for a target group, you'll need to have:
- Your unique account ID:
{account_id}path parameter - Your API authentication token (JWT):
<YOUR_JWT_TOKEN> - Your business unit ID:
<YOUR_BUSINESS_UNIT_ID>
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.
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:
business_unit_id(string, required): This is your unique business unit identifier.locale(string, required): The target locale (e.g., "eng_us"). See our list of supported locales for all valid codes.collects_pii(boolean, required): You should set this totrueif your survey collects personally identifiable information, andfalseotherwise.incidence_rate(number, required): Your expected survey incidence rate (IR) as a decimal (e.g., 0.5 for 50%).length_of_interview(number, required): Your estimated length of interview (LOI) in minutes (e.g., 20).filling_goal(number, required): Your desired number of completes (e.g., 40).start_date(string, required): The start date and time of fieldwork in RFC3339 UTC format.end_date(string, required): The end date and time of fieldwork in RFC3339 UTC format.price(object, conditionally required): 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, required): The monetary value.currency_code(string, required): 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, required): The monetary value.currency_code(string, required): The ISO 4217 currency code.profiles(array of objects, required): An array of profile objects defining your targeting criteria.object(string, required): The profile object type (e.g., "regular").quotas_enabled(boolean, required): Set totrueif quotas are enabled for this profile, otherwisefalse.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.quota(object, required): The quota settings for this target.quota_percentage(number, required): The percentage of the total filling goal allocated to this target (e.g., 50 for 50%).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, required): Defines allocations for the Open Exchange supply source.private_exchange_allocations(object, optional): Defines allocations for the Open Exchange supply source.
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}/target-groups/calculate-feasibility
Reminder, you will need the following to make the request:
- Your unique account ID:
{account_id}path parameter - Your API authentication token (JWT):
<YOUR_JWT_TOKEN> - Your business unit ID:
<YOUR_BUSINESS_UNIT_ID> - Cint API Version:
2025-05-27

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.

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
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
incidence_rateandlength_of_interview. Very low IRs or very long LOIs can severely impact feasibility. - Make sure your
start_dateandend_datedates define a sufficient fielding window.
- Review your
- Placeholders: Make sure you've replaced all placeholder values (e.g.,
<YOUR_BUSINESS_UNIT_ID>,{account_id}) with your actual data before making the request.
