Get Tweet timelines

Frequently Asked Questions

This FAQ addresses questions about the recently announced changes to the /statuses/mentions_timeline and /statuses/user_timeline endpoints.

What API endpoints are impacted by the announcement?

We are announcing that we are limiting access to two of the most commonly used Twitter standard API endpoints – statuses/user_timeline and statuses/mentions_timeline. This change will ensure that we appropriately review how existing apps are using these endpoints, while also making sure that all companies using our APIs to build products for business purposes are doing so fairly and consistently.

What are the new rate limits?

On June 19, 2019, we will begin limiting access to the /statuses/mentions_timeline and /statuses/user_timeline endpoints to 100,000 requests per day as a default. This is a total request limit that applies across both user-auth and app-auth requests. These limits will be on a per-application and per-endpoint basis, meaning that a single developer app can make up to 100,000 calls to each of the two endpoints during any single 24-hour period. The existing default user-auth and app-auth rate limits will not change.

Are we changing the existing user-auth and app-auth rate limits?

No, existing default user-auth and app-auth rate limits are not currently changing. To be clear, as of June 19, rate limits for statuses/mentions_timeline and statuses/user_timeline will be as follows:

  • /statuses/mentions_timeline:
    • 75 requests/15-min window (user-auth)
    • 100,000 requests/24-hour window (application level)
  • /statuses/user_timeline:
    • 900 requests/15-min window (user-auth)
    • 1500 requests/15-min window (app-auth)
    • 100,000 requests/24-hour window (application level)

Why are you making this change?

As noted in the blog post, we’re making these changes so we can appropriately review how developers are using these endpoints, and so that access to our APIs is fair and consistent for developers who have built solutions to serve other businesses. Adjusting these rate limits also contributes to our goal of helping people feel safe and protecting their privacy while maintaining open access to our developer platform.

How do I determine if I am impacted by this change?

We have proactively contacted developers who will be impacted via their registered developer email addresses. If you did not receive an email, you’ll need to check if your Twitter developer app is making more than 100,000 requests to either /statuses/mentions_timeline or /statuses/user_timeline endpoints in a 24-hour period. Please see question 7 (option 2) below for details on what to do if you believe your app will be impacted.

How do I check whether I am hitting the endpoint(s) near the request limit?

We do not have an endpoint that provides this information, so you will have to review your logs to track your usage. If you would like to check your usage from the current rate limit window, you can use the application/rate_limit_status endpoint.

What can I do if I am impacted by this change?

Please review the two options outlined below and proceed with the one that best describes your application:

I. My application serves other businesses:

  1. Please complete the enterprise API application via this form with detailed information about your application that makes use of these endpoints.
  2. A Twitter representative will be in touch to discuss available options for continued access. Part of this process will include a review of your application, your use case, and a consultation of the best API solutions available to serve your needs.

II. My application does not serve other businesses:

  1. Make sure that you are logged into your Twitter Developer account.
  2. Follow this link to the API Policy Support Page, where you might see the option: "I would like to apply for elevated user & mentions timeline limits."
    • Important note: If you do not see this option, please double check the Twitter account you're currently logged in with. If you still do not see this option, your application does not qualify for a review at this time because your usage is well below impacted thresholds. Rest assured, if you start making requests at a volume near the rate limit, the proper form option will become available. Based on this, we request that you don’t post to the forums if you don’t see this option unless you actually hit the rate limit.
  3. Complete the form with as much detail as you can about your current use of one (or both) of the mentions and user timeline endpoints. Our team may need to reach out for further clarification if your submission is incomplete or unclear, which may delay a decision about your application. Please provide as much detail as possible.
  4. We will review your submission and notify you of our decision when our review is complete.

Will developers ever be required to migrate off of the user and mentions timeline endpoints?

We are taking a phased approach at changes to our platform, so that we can collect feedback from developers and minimize impact. We want to make sure we understand how and why developers are using them to help inform any changes we might make in the future.
