Improvement: Custom age targeting extends to 75
targetMinAge and targetMaxAge on Create Project and Update draft project now accept integers from 18 through 75, for both B2B and B2C projects. Use this to target older participants directly, for example ages 55 to 70, instead of the 55+ age group.targetMaxAge stays an inclusive cutoff. Setting it to 75 excludes participants older than 75. Omit targetMaxAge to include them.Values above 75, or below 18, still return a 400 error.See Age targeting.
