# Bulk Subscriber Actions

For more information on how to use these endpoints see: [Bulk Create/Update Subscribers](/tutorials/manage-subscribers/bulk-create-update-subscribers.md)

* Bulk Create Subscribers [#post-subscribers-bulk](#post-subscribers-bulk "mention")
* Bulk Update Subscribers [#patch-subscribers-bulk](#patch-subscribers-bulk "mention")

## Bulk Create Subscribers

> \# Record Limit
> \\
>
> \
> This endpoint will accept a maximum of \`1,000\` records in a single request. Records of subscribers should be in an array. The \`createOnly\` field indicates if the action is creating new subscribers only (doesn't accept records of existing subscribers) or the action is creating or updating (accept records of existing subscribers and update info according to the records).
> \
> \
> \
> \# Rate Limiting\
> \
> This endpoint overrides the general rate limit with an account rate limit. Requests are limited by the authenticated account instead of the IP address. This endpoint is limited to \`15\` requests every \`15\` seconds

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://developers.mobile-text-alerts.com/api-reference/subscribers/bulk-subscriber-actions.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
