As we've seen in the articles so far in our , working with APIs you come across a comprehensive terminology that was not invented by Bubble but has been around for years or decades. You can find a list of some these in our .
Bubble also introduces its own terminology to describe different parts of its API. To new users they may seem confusing and sometimes overlapping at first and this article will go in-depth in the different terms we use.
Bubble API
Umbrella term for the Data API and Workflow API
Data API
The part of the Bubble API that deals with direct requests to the database
Workflow API
The part of the Bubble API that deals with requests to trigger API workflows
API Workflow
The workflow itself that you create and manage in the backend editor
Backend workflow
Umbrella term for the different workflows available in the backend editor (API Workflow, Database Trigger, Recurring event and Custom event)
The term Bubble API describes the full suite of API capabilities that Bubble can offer to other applications. In other words, any incoming connection to your application is connecting to the Bubble API.
You can see the Bubble API as an umbrella term for the Data API and Workflow API.
The API Connector, which is used to establish outgoing connections to other applications is as such not a part of the Bubble API. We can illustrate the reason for this with an example moving outside of Bubble:
Let's say you are initiating a connection with a Weather API to get updated weather information. That Weather API service may also use one or more APIs in order to function: for example, it could be using the Google Maps API to convert an address into map coordinates. That information, while it helps them deliver a better service, is completely irrelevant to you. As such, it's not a part of their API – it would not be presented in their API documentation and you would never know that it was involved in responding to your request.
The same is true for Bubble whenever there's an incoming request: whether your app uses the API Connector to connect to other parties in order to complete a request is irrelevant to the third-party making the request. They simply want to connect to the Bubble API to get a response and what goes on behind the scene is hidden from them.
The Data API is the part of the Bubble API that deals with direct access to the database. This allows a third party to send commands directly to your app's database and get a response it can recognize in return.
If you open up for it, this lets an external application:
Search for and read records in your database
Create new records
Make changes to records
Delete records
Of course this all doesn't happen unrestricted: as we'll see in later sections you have full control over what information and commands they have access to.
In Bubble's terminology, a workflow is the combination of an event and a set of actions that should be run as a result of that event. That techie-sounding description is what happens whenever you design something in the workflow editor:
There are several reasons for why direct access to the database makes sense to use in most cases where you are working with data:
The Data API is set up to respond to different queries in a format that other APIs will recognize. It has built-in:
Search for single records and get its data
Search for records by criteria and get their data in a paginated format
Create new Things
Bulk create new Things
Delete Things
Change Things
All of this is possible without spending any time setting up a single workflow.
The Data API gives you granular control over the security of your database:
By requiring you can determine which is making the query, to...
that client to perform certain actions
Find Things
Hide and show specific fields
Create Things
Modify Things
Delete Things
Since this is all controlled in one central place – your app's Privacy Rules – you can apply restrictions to a wide set of clients and circumstances in one central dashboard.
Whenever you want to give a specific app flexible access to your database. Let's go over a few examples to say when the Data API would be the more practical and secure API method:
Case 1: Customer signup to lead
Let's say you have built a CRM for your company in Bubble, but your website is in a different framework such as Wordpress. Each time a potential client signs up using the contact form on your website, you would like to create a lead in your CRM.
Case 2: Project hours info to invoice
This time, let's imagine you have built a project management in Bubble, but the invoices are handled by a separate accounting app. By opening up your database to that accounting app they can get an up-to-date list of work hour logs whenever they need to generate an invoice.
In short, whenever you need to read or update information in the database and all the parameters needed are available when the request is sent, the Data API is usually the better choice.
As we explored in our last definition, the Workflow API allows external applications to trigger an in your app by . A workflow can perform any set of actions that you need to perform.
Let's re-visit our example from earlier:
In contrast to the Data API, the Workflow API can perform all sorts of actions with or without involving the database. Just like with workflows on your pages, you can set up a sequence of steps, each with unique conditions to determine whether to execute or not.
You can see the Workflow API in the same way as a user visiting a page in your app: they can click a button (make a request) that instructs your app to perform one or more actions that are run in sequence.
While workflows can perform database operations, a database operation is not necessarily performed by a workflow. There are many reasons for choosing the Workflow API over the Data API:
API Workflows can run any kind of that Bubble (including plugins) can offer, such as sending emails, resetting passwords, submitting API calls and lots more.
Workflows often consist of more than one action that can be run in sequence, and each step can if needed rely on a previous step. The Data API will simply perform the requested action and respond with a preset response whereas the Workflow API gives full flexibility as to what kind of unlimited number actions you want to take.
A Workflow can also trigger other workflows in your app.
The Data API sends a response back in a format that's recognized by many other systems, but if you need to customize what the response to a call looks like, you can use the Workflow API to set it up.
In short, whenever you need more flexibility in how data is manipulated, or when you need the API call to lead to executing actions that are not related to the database.
Case 1: Follow-up steps
Even when making changes in the database is what you're looking for, the Workflow API can be the right choice. For instance, an app may need to:
Create a new Thing
Count all Things of the same type
Send an email to an address specified in the request with the total count
In this case we are working with the database, but since we also want to perform a few specific actions that rely on the first step it would make sense to set this one up in the Workflow API.
It might look something like this:
Case 2: Using complex conditions
In scenarios where you rely on in order to determine whether an action should be performed the Workflow API also comes in handy. Let's say your app needs to:
Create a new Thing
But only if today is a Friday and a maximum of 3 Things have been created today
A condition like that would involve checking the current day of the week and count the number of Things created today – this complex condition wouldn't be possible to set up in Privacy Rules and would need an API Workflow where you could place the condition in the Only when field.
We could provide a lot of different examples, but the important point is that the Data API is used only to read/manipulate data and send a preformatted response, and the Workflow API is used to trigger a workflow that can be set up to run any actions you want.
While these two terms are indeed closely related, they mean different things.
The Workflow API is the part of the Bubble API that handles workflows.
An API Workflow is the workflow itself that you set up in the backend workflow editor.
As such the Workflow API consists of API Workflows, and API Workflows are part of Bubble's Workflow API.
Bubble's is the section of the Bubble editor where you create and manage backend workflows.
Backend workflows is the umbrella term for any type of workflow you can create in the backend editor.
These are server-side workflows, meaning that they can run on the Bubble server without anyone visiting one of your app's pages. This includes, but is not limited to, API Workflows.
By setting up Wordpress to send an API request to the Bubble Data API, you can create a new lead in the Bubble database using the .
