Request object

1. A JSON object with the relevant campaign fields.
2. The minimal set of fields are:
   1. country_targeting
   2. platform_targeting
3. For more accurate results, pass additional fields.

🚧

Guidelines

1. Leaving out the minimal fields (above) will generate an unrealistically broad estimate. (However, the system does not validate for their presence.)
2. You can pass all available fields. Fields that do not affect the reach estimate - e.g. postal_code_targeting - will simply be ignored.
3. Note that campaign budget and scheduling do not affect the estimate.

See Rate limits for the request allowance each tier carries.
