API overview

This reference article covers the API basics including common terminology and an overview of REST API keys, permissions, and how keep them secure.

API definitions

The following lists an overview of terms you may see in the Braze REST API documentation.

Endpoints

Braze manages a number of different instances for our dashboard and REST endpoints. When your account is provisioned you will log in to one of the following URLs. Use the correct REST endpoint based on which instance you are provisioned to. If you are unsure, open a support ticket or use the following table to match the URL of the dashboard you use to the correct REST Endpoint.

Instance	URL	REST Endpoint	SDK Endpoint
US-01	https://dashboard-01.braze.com	https://rest.iad-01.braze.com	sdk.iad-01.braze.com
US-02	https://dashboard-02.braze.com	https://rest.iad-02.braze.com	sdk.iad-02.braze.com

API limits

For most APIs, Braze has a default rate limit of 250,000 requests per hour. However, certain request types have their own rate limit applied to better handle high volumes of data across our customer base. For details, refer to API rate limits

User IDs

• External user ID: The external_id serves as a unique user identifier for whom you are submitting data. This identifier should be the same as the one you set in the Braze SDK in order to avoid creating multiple profiles for the same user.
• Braze user ID: braze_id serves as a unique user identifier that is set by Braze. This identifier can be used to delete users through the REST API in addition to external_ids.

For more information, refer to the following article based on your platform: iOS, Android, and Web.

REST API key

A REST Application Programming Interface key (REST API key) is a unique code that is passed into an API to authenticate the API call and identify the calling application or user. API access is done using HTTPS web requests to your company’s REST API endpoint. We use REST API keys at Braze in tandem with our App Identifier keys to track, access, send, export, and analyze data to help make sure everything is running smoothly on both your and our end.

Workspaces and API Keys go hand in hand at Braze. Workspaces are designed to house versions of the same application across multiple platforms. Many customers also use workspaces to contain free and premium versions of their applications on the same platform. As you may notice, these workspaces are also making use of the REST API and have their own REST API keys. These keys can be individually scoped to include access to specific endpoints on the API. Each call to the API must include a key with access to the endpoint hit.

We refer to both the REST API key and workspace API key as the api_key. The api_key is included in each request as a request header and acts as an authentication key that allows you to use our REST APIs. These REST APIs are used to track users, send messages, export user data, and more. When you create a new REST API key, you will need to give it access to specific endpoints. By assigning specific permissions to an API key, you can limit exactly which calls an API key can authenticate.

REST API key permissions

API key permissions are permissions you can assign a user or group to limit their access to certain API calls. To view your list of API key permissions, go to Settings > API Keys, and select your API key.

• user data
• email
• messages
• campaigns
• canvas
• segments
• purchases
• events
• news feed
• sessions
• kpis
• templates
• sso
• content blocks
• preference center
• subscription
• sms
• catalogs

Creating REST API keys

To create a new REST API key:

1. Go to Settings > API Keys. This page displays your existing API keys.

2. Click + Create New API Key.
3. Give your new key a name for identification at a glance.
4. Select which permissions you want to be associated with your new key.
5. Specify allowlisted IP addresses and subnets for the new key.

Managing REST API keys

REST API keys cannot be edited after they are created, however, you can view details for or delete existing REST API keys from the API Keys page. The Rest API Keys list shows the following information at a glance for each key:

Field	Description
API Key Name	The name given to the key upon creation.
Identifier	The API key.
Created By	The email address of the user who created the key. This field will show as “N/A” for keys created before June 2023.
Date Created	The date this key was created.
Last Seen	The date this key was last used. This field will show as “N/A” for keys that have never been used.

To view the details for a specific key, select a key from the list. You can then see all the permissions this key has, whitelisted IPs (if any), and if this key is opted into Braze IP whitelisting.

To delete a key, click and selecting the corresponding option.

REST API key security

API keys are used to authenticate an API call. When you create a new REST API key, you need to give it access to specific endpoints. By assigning specific permissions to an API key, you can limit exactly which calls an API key can authenticate.

Given that REST API keys allow access to potentially sensitive REST API endpoints, secure these keys and only share them with trusted partners. They should never be publicly exposed. For example, do not use this key to make AJAX calls from your website or expose it in any other public manner.

A good security practice is to assign a user only as much access as is necessary to complete their job: this principle can also be applied to API keys by assigning permissions to each key. These permissions give you better security and control over the different areas of your account.

If accidental exposure of a key occurs, it can be deleted from the Developer Console. For help with this process, open a support ticket.

API IP allowlisting

For additional security, you can specify a list of IP addresses and subnets which are allowed to make REST API requests for a given REST API key. This is referred to as allowlisting, or whitelisting. To allow specific IP addresses or subnets, add them to the Whitelist IPs section when creating a new REST API key:

If you don’t specify any, requests can be sent from any IP address.

Ruby client library

If you’re implementing Braze using Ruby, you can use our Ruby client library to reduce your data import time. A client library is a collection of code specific to one programming language—in this case, Ruby—that makes it easier to use an API.

The Ruby client library supports the User Endpoints.
