Overview

You may use the Threads API to enable people to create and publish content on a person’s behalf on Threads, and to display those posts within your app solely to the person who created it.

Rate Limiting

Calls to the Threads API are counted against the calling app's call count. An app's call count is unique for each app and app user pair and is the number of calls the app has made in a rolling 24-hour window. It is calculated as follows:

Calls within 24 hours = 4800 * Number of Impressions

The Number of Impressions is the number of times any content from the app user's Threads account has entered a person's screen within the last 24 hours. Rate limiting may also be subject to total CPU time per day:

720000 * number_of_impressions for total_cputime
2880000 * Number of Impressions for total_time

Note: The minimum value for impressions is 10 (so if the impressions is less than 10 we default to 10).

Posts

Threads profiles are limited to 250 API-published posts within a 24-hour moving period. Carousels count as a single post. This limit is enforced on the POST /{threads-user-id}/threads_publish endpoint when attempting to publish a media container. We recommend that your app also enforces the publishing rate limit, especially if your app allows app users to schedule posts to be published in the future.

To check a profile's current Threads API rate limit usage, query the GET /{threads-user-id}/threads_publishing_limit endpoint .

Note:This endpoint requires the threads_basic and threads_content_publish permissions.

Fields

Name	Description
`quota_usage`	Threads publishing count over the last 24 hours.
`config`	Threads publishing rate limit config object, which contains the `quota_total` and `quota_duration` fields.

Example Request

curl -s -X GET \
  "https:graph.threads.net/v1.0/<THREADS_USER_ID>/threads_publishing_limit?fields=quota_usage,config&access_token=<ACCESS_TOKEN>"

Example Response

{
  "data": [
    {
      "quota_usage": 4,
      "config": {
        "quota_total": 250,

      }
    }
  ]
}

Replies

Threads profiles are limited to 1,000 replies within a 24-hour moving period.

To check a profile's current Threads replies rate limit usage, query the GET /{threads-user-id}/threads_publishing_limit endpoint . See the Reply Management documentation for more information.

Note:This endpoint requires the threads_basic , threads_content_publish , and threads_manage_replies permissions.

Fields

Name	Description
`reply_quota_usage`	Threads reply publishing count over the last 24 hours.
`reply_config`	Threads reply publishing rate limit config object, which contains the `quota_total` and `quota_duration` fields.

Example Request

  "https://graph.threads.net/v1.0/<THREADS_USER_ID>/threads_publishing_limit?fields=reply_quota_usage,reply_config&access_token=<ACCESS_TOKEN>"

Example Response

{
  "data": [
    {
      "reply_quota_usage": 1,
      "reply_config": {
        "quota_total": 1000,
        "quota_duration": 86400
