Unexpected response when using followers_of_users in reach estimate

[Ziganja]

Hello!

So, what I gather going through reach estimate documentation is
that you can send a comma separated string of user ID’s as a targeting for followers_of_users, all good.

But, the problem is even if I use the ID supplied in the example (756201191646691328) I get this response:

.

Is there a bug, or am I doing something wrong?

Thanks!

Thanks for the question, @Ziganja.

The followers_of_users parameter can only include users that the account has access to promote. (I realize this is not currently documented.)

To get a list of the users that the ads account can promote, use the GET accounts/:account_id/promotable_users endpoint.

Here is an example request using followers_of_users parameter in a reach estimate request:
