This article is part of a significant update to the Bubble manual and your feedback is critical to our efforts to continuously enhance our written documentation. We would greatly appreciate if you could take a moment to let us know your thoughts on the quality of it. Thank you for your support!
The last section covered how APIs, and in particular, work from a technical perspective. Ins this section we'll have a closer look at how APIs work in Bubble.
This is the in-depth manual article series on Bubble’s API. If you want the shorter, technical reference, check out the Bubble API Reference entry:
Reference:
Bubble is designed to make it easy to connect to both other Bubble applications and external APIs in a highly flexible, secure and compatible way. Most of the highly technical stuff like setting up your app to be able to receive incoming API requests happens automatically by the click of a few buttons and offers the same functionality and security as a more resource-demanding traditionally coded application.
Because Bubble adheres to widely used web standards your application can connect to almost any other system.
The Bubble API is used whenever you want to accept incoming API requests.
Incoming requests happen when an external system, such as another application, initiates a connection with your Bubble application. In that case, your app needs to be ready to accept that request and know what to do with it.
Incoming requests to Bubble can do one of two things:
Search for, Read, create, modify or delete data in your database: this is handled by the Data API.
Run a workflow in your app: this is handled by the Workflow API.
We’ll explore how affect both the Data API and API Workflows in each section.
This means that you can set up Privacy Rules that govern the access level of not only all API clients, but individual API clients since each of them can authenticate as an existing User.
Privacy Rules determine what kind of access a user that matches specific criteria has to each data type in your app. You can view any external system (client) that tries to access your app’s API as simply another user: this is true not only in a metaphorical sense but in a real one. Bubble treats it like a user that can be logged in or not, and in certain scenarios you can even save data to it just like any other user profile.
Both the Data API and API Workflows respect your app’s Privacy Rules. This is why setting them up correctly is an essential part of constructing your API.
Whenever you activate the Bubble API, it means that you want external systems to reach your application with different kind of queries. Swagger is essentially a way for your API to automatically describe itself so that other systems can understand how it's structured and what queries are available.
In essence, if your API is a restaurant, then the Swagger file is the menu.
For example, to successfully connect to your app, an external app or its developer may have "questions" like:
How to authenticate with your app
What kind of calls are available?
What kind of parameters are there?
What does the response look like?
The Swagger specification speaks a language that answers questions like this in a way that both humans and computers can understand. Bubble uses the JSON format to generate a Swagger file.
The Swagger file is generated automatically by Bubble and is dynamic in the way that it will update according to your app's settings. The Swagger file is disabled by default when the Bubble API is enabled, but you can choose to enable it under Settings - API.
An URL is automatically generated whenever the file is available:
https://appname.bubbleapps.io/api/1.1/meta/swagger.json
or if you are connected to a domain:
https://yourdomain.com/api/1.1/meta/swagger.json
To answer that question, it's first important to emphasize that hiding information about your apps's API does not mean it's secure: obfuscation is not security. So while the Swagger file will expose your endpoints, a determined hacker would be able to reconstruct them anyway. Security is done using authorization and Privacy Rules, not by trying to hide information about the API.
Yes and no: you can't make direct edits to the file, but the file will instantly reflect any relevant changes that you make to your app's settings and structure. You don't need to keep track of these changes yourself.
Yes, there are separate URLs and files for the two different versions. Remember to point the external application to the correct file. Also, keep in mind that changes you make in your app's development version are not reflected in the live Swagger file until the app is deployed.
The Swagger file is dynamic in the way that it will look different based on how your application is set up. The example below can give you an idea of the basic structure. In this example, both the Data API and the Workflow API are activated:

}Whenever a attempts to connect your app's , you can require them to authenticate themselves. Authentication is the process of identifying who a client is in order to determine what they have access to your your application. This article explains the three different ways a client can authenticate. Article:
Calls that are made to your app as a response to a specific event (such as a successful or failed payment) are often called webhooks. Article section: (with examples)
The Data API can give external applications access to your app's database to read, create, edit and delete records. This article explains how to set up the Data API and how to send requests to your app. Article: Reference:
The Workflow API lets you set up API workflows that can be triggered from outside of your own application without visiting any page. This article explains how to activate the Workflow API, how to create API workflows and finally how to access those workflows from an external system. Article: Reference:
