Example - An email verification API, TheChecker (opens new window)will be used as an example for how to create and edit a Mini-App.

To create an app, follow steps 1 to 6 in the above screenshot.

On the editing page (left), list a title, description, logo, cover page, YouTube video id and it will appear like this in the mini-app store (right):

On the right side of the editing page:

You can always use sample data at the bottom for guidance. And system fields are what you can use in your JSON code if needed.

Auth

This block is for setting authentications of your App.

Parameters

Name	Data Type	Description

Name	Data Type	Description
type	enum	Supported value: APIKEY
params	array	Values required from users when installing e.g. API key
request	object	Send requests with parameters (e.g. email, api_key) and map the response to params (e.g. token)
connection	object	List of request headers or parameters

Email Verification Example

This is an authentication example with an API key in the query. As follow is how it will look like after users install the App:

The "api key" set by users will then be stored in the variable "token".

Basic Auth Example

TIP - The basic access authentication requires the username and password joined by a single colon to be a credential and the credential encoded by using Base64. Given that the functions are not supported in the JSON code, the system will help you do the encoding. So you just need to put "Basic [[sid]]:[[token]]" as the authorization value.

{
    "type": "APIKEY",
    "params": [
        {
            "name": "sid",
            "title": "Twilio Account SID:"
        }，
        {
            "name": "token",
            "title": "Twilio Auth Token:"
        }
    ],
    "connection": {
        "headers": {
            "Authorization": "Basic [[sid]]:[[token]]"
        }
    }
}

Other Examples

Example 1: APIKEY Auth, headers

{
    "type": "APIKEY",
    "params": [
        {
            "name": "token",
            "title": "Enter your api key:"
        }
    ],
    "connection": {
        "headers": {
            "Authorization": "Bearer [[token]]"
        }
    }
}

The "headers" in the "connection" will be added to each request, so you don't need to repeat it everywhere later.

Example 2: APIKEY Auth, query parameters

{
    "type": "APIKEY",
    "params": [
        {
            "name": "api_key",
            "title": "Enter your api key:"
        }
    ],
    "connection": {
        "qs": {
            "key": "[[api_key]]"
        }
    }
}

Same as above, the query string will be added to each request.

Example 3: APIKEY Auth, JWT token

The email and api_key provided by users will be sent as a request. Then the responses will be mapped to variable token by JSON path $.data.token. After that, it's used as a variable [[token]] in an authorization header. Again, the header will be added to each request later.

Actions

Actions are what functions/features users can do with your App. For example, this "Google Translate" App has 2 actions, "Detect Language" and "Translating text":

In the coding area, you need to set the default information of the action, including name, title, description, forms and requests to make the action work in the flow with configuration.

At the bottom, click "Get product" for a GET request example, and "Update product" for a POST request example. The type of forms and requests are objects, therefore it needs to set several attributes.

Parameters

Name	Data Type	Description

Name	Data Type	Description
name	string	Identify the action, must be unique
title	string	Action title shown when using the app
description	string	Action description shown when using the app
forms	array	List of form objects for action configuration
requests	array	List of request objects to be performed in succession

Form Object

Name	Data Type	Description

Name	Data Type	Description
name	string	Field name, used as an identifier and variable inside request
type	enum	Value type, used for validation, supported values: string, text, number and select
title	string	Field title, displayed in UI
default	string	Default value for this field, If specified, the field becomes optional
source	string	Name of the source in Sources block, only for type=select
placeholder	string	the grey prompt shown in the field
description	string	the prompt appears below the field

Lines in Text Variable

TIP - The difference between string and text form type is that, string will remove the newline in the variable while text will keep it.

Request Object

Name	Data Type	Description

Name	Data Type	Description
url	string	Request URL
method	enum	HTTP request method, supported values: GET, POST, PUT, DELETE, PATCH, HEAD, OPTIONS
headers	array	List of request headers in key value pair, e.g. `{"Content-Type": "application/json"}`
payload	json	Request body
body_format	enum	Request body format, supported values: json, query, form, multipart, raw
mapping	array	Set of fields for request results mapping into custom fields

Mapping Object

Name	Data Type	Description

Name	Data Type	Description
name	string	Field name, used as identifier
type	enum	Field type, supported values: text, number, boolean, date, datetime, array
title	array	Field name, displayed in UI
path	string	String in a JSON path format

Example 2:

Sources

Sources block is used to provide users with a list of options for the form value. Use the name of the source in the form parameter in the Actions block to build the connection.

There are 2 sources formats, static and dynamic. The options from a static source are fixed while a dynamic source brings changing options according to inputs.

Parameters

Name	Data Type	Description

Name	Data Type	Description
name	string	Identify the source
type	enum	Source type, supported values: enum:rpc, enum:static
list	array	List of fixed options shown when using the App. Only for type=enum:static
request	object	Request object when the source is dynamic. Only for type=enum:rpc

Mapping Object in the Request Object

Name	Data Type	Description

Name	Data Type	Description
type	enum	Field type, supported value: select
path	string	String in a JSON path format, for response data array
value	string	String in a JSON path format based on the `path` results. This is the real value returned when a label is selected
label	string	String in a JSON path format based on the `path` results. Displayed in the drop-down list as label

Triggers

By setting triggers, users can use the triggers from the automation section like any other built-in triggers shown in the above screenshot.

Please note that the trigger name has to be:

in lower case
unique in the trigger list
no space, you can separate words by underscores

Context is where you list all the pre-set variables when data coming in.

After setting the trigger, you will need to configure the "API Token Requests" and select the API in "API Scopes", see guidance below.

To call this trigger, see API for mini-app trigger.

Api Scopes

In "Api Scopes", select all the APIs that your mini-app need to access. Check "Api Documentation" via the link on the top.

For example, if your app needs to view users' tag list in their flow, select "View flow tags". Besides, if you need to use triggers in your app, do select the "App Trigger" in the screenshot above.

Api Token Requests

In "Api Token Requests", click the "Requests" sample data at the bottom, and edit the URL address to your endpoint for subscription and unsubscription. Also, have a check at the bottom for available system fields and put what information you need in the payload. For example, do include "app_token" in the payload if you need to access users' flow via API (if you select any API in Api Scopes block).

Save & Test

Finally, click "Save" to finish the creation. Congrats!! You've just made a Mini-App successfully.💯💯

If you are just using the app in your own workspace, then you don't need to publish the app. You can test it and use it in any bot of any channel in your workspace.

To share the app to other workspaces, you will need to publish your app in UChat's mini-app store.
