All Facebook ad managers are occasionally teased by the system about obtaining a Post ID to use for leveraging the same ad post across multiple ad sets and campaigns. The benefit of reusing Post IDs for your ads is that you'll be leveraging the social proof that the ad has already racked up. If you just duplicate the original post and run the ad, you are running visually the same ads, but they are two different ads with different IDs in the system.
Post ID's in Facebook Meta Business Suite
First of all, let's take a look at what Facebook's official help advises us:
To find the Page post ID in Ads Manager:
Go to Page posts.
Select Published posts in the menu.
Select the post you'd like to identify.
Post details, including your Page post ID, will appear.
But if we follow this path, we find that there is nothing in Publish Posts after the last interface redesign.
After switching to Meta Business, we will only get to the contributions and the necessary IDs.
So we got to ID in a more complicated way, but the number of steps that need to be taken is too many and all of this takes time.
Post ID's by Facebook Ads Preview
The second way is available directly from the Facebook Ads interface. You choose this method:
A) Select the ad and select Preview.
B) Then select Share Previews and after that, select option Facebook Posts with comments.
C) You will then see a full preview of the ad in a new window. The URL is important and is in the form:
D) We are interested in the part of the URL after /posts/,

E) Copy and paste this part into existing posts under "Enter Post ID".
Facebook Post ID's by Supermetrics
If you follow my blog, you'll know that I'm a long-time user of Supermetrics, a tool that makes reporting and action steps for campaigns easy. Finding Post ID's for Facebook is no exception. This solution is by far the fastest and especially for the larger number of Post ID's needed.
As you can see, even within Supermetrics it is not possible to pull the Post ID for an ad directly through their API.
We have two options, either pull from the Link to Posts segment the last part after the "/" or by splitting the Promoted Post ID.
If you don't know regular expressions, use ChatGPT with the help of this prompt:
I need from these inputs, to create a regular expression that will pull only the values after the last /.
So the result will be, for example, 100728513112311.
The results is:
[^/]+$
This regular expression is then implemented in the REGEXTRACT function, which extracts only the necessary last part of the link.
Next prompt for AI is:
Implement this entry in the REGEXTRACT function in Google Sheets.
The whole formula is now in the form:
=REGEXEXTRACT(F2, "[^/]+$")
F2 is a link to the field in which the link is placed.
If you prefer to use the Split function, then the formula is based on the input value of the C2 array:
=SPLIT(C2, "_")
I prefer to use Link to Post, because I also find the link to the post very useful for my review.
The data from this report is obtained from Supermetrics. However, you can use other tools in the same way if they allow you to connect to the Facebook Ads API.
