The Facebook Post API is a powerful tool that allows developers to publish and manage posts on behalf of a Facebook Page. To get started, you'll need to create a Facebook Developer account and register your app.
The API requires you to have a Facebook Page with a verified business manager account, which is necessary for publishing posts. This ensures that your content meets Facebook's policies and guidelines.
To publish a post, you'll need to make a POST request to the Facebook Graph API endpoint, specifying the post content and other relevant details. The API will then create a new post on your Facebook Page.
With the Facebook Post API, you can also manage existing posts, including editing or deleting them. This is done by making a PATCH or DELETE request to the relevant API endpoint, respectively.

Getting Started
To start using the Facebook Graph API, you'll need to familiarize yourself with its basic principles. The Graph API follows a simple programming model called the social graph.
Every concept or object on Facebook is represented as a node, which is a unique ID with its details available at a node endpoint like https://graph.facebook.com/{version}/{ID}. The docs list all the nodes.
Relationships between nodes are represented by edges connecting them, and can be read and modified through an edge endpoint like https://graph.facebook.com/{version}/{id}/{relation}. For example, to get all the group nodes of user ID 500, the endpoint is https://graph.facebook.com/{version}/500/groups.
To fetch any type of content, just traverse the social graph from node to node, usually starting from a user node, and make requests on the relevant edge endpoints until you reach the target node.
Here's a summary of the basic principles of the Graph API:
- Concepts are nodes
- Node endpoints: Every node has a unique ID with its details available at a node endpoint
- Relationships are edges
- Edge endpoints: Every edge relationship can be read and modified through an edge endpoint
Creating a Post
Creating a post on Facebook using the Graph API is a straightforward process. You can post on a page, but not directly on a user's feed.
First, you need to get the user's pages by querying the pages API /me/accounts endpoint with their user access token. Your app should have the pages_show_list scope for this to work.
You'll receive a list of user-administered pages with their details and page access tokens in the data field of the response. Store the page IDs and access tokens against the user in your database.
To create a post, you'll need to request the /{page-id}/feed endpoint of the selected page. You'll need the page ID and access token, which you stored earlier.
Here's what you'll need to send in the request:
- {page-id}: The ID of the target page in the data list
- {page-access-token}: The access token of the target page in the data list
- Request body: Post object in JSON format, with a "message" property to set the text and a "link" property to include an image or other media
- Header 'Content-Type': 'application/json'
Your app should have the pages_manage_posts scope for this to work. The response will be the ID of the new post.
If you want to publish a photo or video, you can send a POST request to the /page_id/photos endpoint. Set the url parameter to the photo or video URL. On success, you'll receive a JSON response with the ID of the photo and the post.
Here are the details you'll need for a photo post:
Note that you'll need the page ID and the photo URL to make this request.
Managing Posts
Managing Posts is a breeze with the Facebook Post API. To update a post, send a POST request to the /page_post_id endpoint with the new content.
You can update any post by sending a POST request to the corresponding endpoint. This is a great way to keep your content fresh and engaging.
To delete a post, simply send a DELETE request to the /page_post_id endpoint where page_post_id is the ID of the post you want to delete. This will remove the post from your page entirely.

Get Analytics
To get analytics for your Facebook posts, you can use the Graph API's /{id}/insights endpoint.
You'll need a page access token, which can be obtained from the /me/accounts endpoint.
The Graph API reports impressions, engagements, reactions, and more for each page or post.
Your app should have pages_read_engagement and read_insights permissions to access this data.
You can also use Ayrshare's /analytics endpoint to get insights on your posts' engagement, impressions, and reactions.
A unique perspective: Print Tumblr Posts
The JSON response from Ayrshare's /analytics endpoint will provide you with the analytics data.
Here are the required parameters to get analytics for a post using the Graph API:
- post-id: The id of a post reported by a /{page-id}/feed endpoint.
- metric={metric1,metric2,...}: The list of metrics you’re interested in.
- page-access-token: A page access token for the page reported by the /me/accounts endpoint.
Make sure to replace post-id with the actual id of the post you're interested in.

Permissions and Access
To post on a Facebook page, you need a Page Access Token, which grants your app the permissions needed to post content on your behalf. This token is crucial for posting, reading, and analytics on a page.
To get a Page Access Token, you need to select the page you want to post to and add the necessary permissions. You can do this by going to the User or Page section, choosing Get Pages Access Token, and following the prompts to switch accounts if necessary.
The necessary permissions include pages_show_list, pages_messaging, pages_manage_posts, pages_read_engagement, pages_manage_engagement, and pages_read_user_content. You can add these permissions in the Graph API Explorer by going to Tools > Graph API Explorer and clicking on Generate Token.
To publish a post to a Page, you need to send a POST request to the /me/feed endpoint, where page_id is the ID of your Page, with the following parameters.

Graph Permissions

Graph Permissions are crucial for accessing and managing your Facebook page's data. You need to add the necessary permissions to your app, which can be done in the Graph API Explorer.
To add permissions, go to Tools > Graph API Explorer and select the permissions you need. Some required permissions include pages_show_list, pages_messaging, pages_manage_posts, pages_read_engagement, pages_manage_engagement, and pages_read_user_content.
Here are the specific permissions you'll need to add to your app:
By adding these permissions, you'll be able to access and manage your Facebook page's data, including posting content, reading engagement data, and managing messages.
Link Ayrshare to Account
Linking Ayrshare to your account is a straightforward process. To post on your or your organization's pages and groups, you must link your Ayrshare account with your (or your organization's) Facebook account.
You'll need to authorize Ayrshare's API to act on your behalf for this to work. This is a one-time setup that allows Ayrshare to manage your Facebook posts.
Creating user profiles for each user-page and user-group pair is a good idea if you have multiple users with different publishing responsibilities. This will make it easier to manage access and permissions.
Each user will need to link their user profiles to their Facebook account and desired page or group. This is a simple process that requires no additional setup beyond linking your Ayrshare account.
You don't need to go through the hassle of application registration, app review, or OAuth flows to get started.

Limitations and Notes
When using the Facebook Post API, there are some important limitations and notes to keep in mind.
The publish date of a scheduled post must be between 10 minutes and 30 days from the time of the API request. This means you can't schedule a post too far in advance or too close to the current time.
If you're relying on strtotime()'s relative date strings, be aware that you can read-after-write the scheduled_publish_time of the created post to verify it. This can be a useful check to ensure your scheduling is working as expected.

Limitations
One major limitation of our current understanding is that we can't predict the exact timing of these events.
The article notes that these events can occur at any time, making it difficult to prepare for them.
Our current models can only provide general estimates of when these events might happen, but they can't pinpoint the exact date or time.

The data we have collected so far suggests that these events tend to happen in clusters, rather than randomly throughout the year.
This clustering effect can make it seem like these events are more frequent than they actually are.
The article also mentions that the accuracy of our predictions decreases as we look further into the future.
This means that while we can make relatively accurate predictions for the short-term, our predictions become less reliable as we try to forecast further ahead.
Notes About Scheduled
When scheduling posts, there are some important notes to keep in mind.
The publish date must be between 10 minutes and 30 days from the time of the API request.
If you're relying on strtotime()'s relative date strings, you can read-after-write the scheduled_publish_time of the created post to verify it.
Audience Targeting and CTAs
You can limit who sees a Page post by adding the targeting.geo_locations object or the feed_targeting.geo_locations parameter in your POST request.
To access publicly shared Page posts, your app needs to be approved for the Page Public Content Access Feature, but keep in mind that pages cannot message other pages.
Posts with message CTAs can't be accessed using another Page's access token.

Add Audience Targeting
You can add audience targeting to limit who can see a Page post by adding the targeting.geo_locations object or the feed_targeting.geo_locations parameter in your POST request.
To do this, you'll need to specify the geographic locations you want to target. This can be done by including the targeting.geo_locations object in your POST request.
By adding audience targeting, you can ensure that your Page post is only seen by people in the specific locations you've targeted. This can be a powerful way to tailor your content to specific audiences.
The targeting.geo_locations object can be used to target specific countries, states, or cities. For example, you could use it to target people in New York City or California.

Message CTA
Message CTAs can be tricky to navigate, especially when it comes to accessing them through another Page's access token.
Any access token can be used to request publicly shared Page posts as long as your app has been approved for the Page Public Content Access Feature.
Posts with message CTAs cannot be accessed using another Page's access token since pages cannot message other pages.
