Facebook marketing api audience limit

Question

When using marketing api

About this part...

You can add an unlimited number of records to an audience , but only a maximum of 10000 at a time . It may take up to 1 hour before Facebook adds users to an audience, and up to 24 hours for deleting users from an audience.

Is there limit adding user to audience per hour to 10000?

or

when calling

$emails = array(
'test1@example.com',
'test2@example.com',
'test3@example.com',
);
$audience>addUsers($emails,CustomAudienceTypes::EMAIL);

there is limit of 10000 data in $emails each call?

I can't seem find clear explanation, and already post it through facebook marketing developer community group, but still no answer.

My current understanding there is limit of 10000 data in $emails each call. Not sure though.

Answer 1

You are correct that it is for each call. I have uploaded around 75,000 before and had to use multiple calls.
