!! Offer Ads has been deprecated from the Facebook API, which means you are not anymore able to create these ads in Smartly either.
Offer Ads help to advertise discounts and promotions to consumers. People can claim, save and redeem your offers, and Facebook will remind people with a notification about offers they have saved before the offer expires.
Creating an offer?
You can create a new Offer on the creative tab or you can select an existing Offer for your ads. Offers created in Smartly.io are visible only in Smartly.io and Facebook's Ads Manager. Offers will not become visible to your page when created, however, depending on the publishing selection of the creative, the post might be published.
Creating Offer Ads
Offer Ads can be created by selecting Offer Claims, Conversions, Link Clicks or Store Visits as the campaign objective. On the campaign tab, select also the page that you plan to use in your campaign:
On the creative tab, select the offer you want to use with your creative. Offers created in Smartly.io and in Facebook for the page are visible in this drop-down menu.
The link of the creative needs to be the same as in the offer link and the offer needs to be live until the end of the campaign.
Offer ads promoting a mobile app
You can also use offers to promote your mobile app. For a mobile app ad, you can create an offer that promotes the mobile app. Just use the application store URL in the offer's redeem link.
For the ad, select a mobile app offer from the offer listing
Offers in Dynamic Ads campaigns
It's possible to add an offer to a Dynamic Ads campaign by selecting Promote Offer on the Campaign tab.
Offers are only available for Carousel ads as a separate card alongside the dynamic cards. You can customize how it looks like under Offer Card on the Dynamic Creatives tab.
It's not possible to add offers in existing Dynamic Ads campaigns.
How can I verify how my Offer Ad will look like?
The preview of the creative itself can be seen in Smartly. To see how the creative and the offer will look like, use the Ads Manager preview to see the ad on your Facebook Newsfeed or Mobile Device.
How can I create an offer using Unique Promo codes?
Currently, it is not possible to add unique promoting codes to Offer Ads created in Smartly.io because this functionality is limited by Facebook at the moment. If you are able to create the Offer on Facebook by using Unique Promo codes, then it can be used in Smartly.io as well. For more information, regarding Facebook's format, see Facebook's help on uploading Promo Codes..
