Research Defender's Predupe

PureSpectrum’s Buy API can accept your system’s “External Project ID”. We are able to use this value when checking Research Defender’s Predupe API, in addition to use cases with reporting.
To use Predupe - please reach out to our team so that we can enable this on an account level.
Make sure that the value in external_project_id corresponds to the value you use in the field sy_nr in the Research Defender API request.
The value for external_project_id can be passed in both the survey creation and the survey update endpoint requests.
