Frequently asked questions

How do I get the post_id?

Use the Page Posts, Group Posts, or Search Posts endpoints — each post they return includes a post_id field. Both pfbid and numeric post IDs are accepted.

Are replies included?

The endpoint returns top-level comments only. Each comment includes a replies_count showing how many replies it has.

How does pagination work?

Use the pages parameter to fetch multiple pages of results in a single request (1-10). Each page returns up to ~10 comments and is billed separately. Default is 1 page.

What if a post doesn't exist or has no comments?

A nonexistent or unavailable post returns an empty comments array, as does a post with no comments.

How does pricing work?

You only pay for successful requests. The Facebook Post Comments API costs $0.008 per page. There are no monthly fees or commitments. You get 50 free requests per endpoint every month.

Do I need a credit card to start?

No. You can sign up and use the free tier (50 requests/endpoint/month) without adding a payment method. You only need to add a card when you want to exceed the free tier.

Are there rate limits?

Yes, there's a concurrency limit of 3 simultaneous requests per endpoint per user. If you need more, just get in touch.
