问题
I am trying to create dynamic Facebook ads using marketing API in the sandbox account. I am following this document. Now I am unable to create adcreatives. I am getting this error "Ads creative post was created by an app that is in development mode. It must be in public to create this ad.".
Here is my code :
try {
$response = $fb->post(
'/act_<SANDBOX_ACCOUNT_ID>/adcreatives',
array (
'name' => 'Sample Creative',
'object_story_spec' => '{ "link_data": { "image_hash": "5d9cdde5f43dffdec3165e06c1bc3f21", "link": "https://scontent.xx.fbcdn.net/v/t45.1600-4/82783061_120330000035086911_1622348699776581632_n.png?_nc_cat=102&_nc_ohc=np_jpbh2yzIAX8TX6Yt&_nc_ht=scontent.xx&oh=d3c2d425ab9d87154aad9f376eabe8fe&oe=5EC6F7EF", "message": "try it out" }, "page_id": "493348931012140"}'
),
'{access-token}'
);
}
