How to register an app

When you decide to build an app for Hygraph, you must register it on the platform. Apps declare basic information like Name, Description, Avatar URL, API ID and Setup URL. API IDs are unique across all applications. Setup URLs indicate Hygraph where to fetch the content that will display to users that go through your app's setup flow.

To register your application, you first need to navigate to User settings > Your apps, then click on the + Add new app button. This will lead you to the App registration form.

Your apps

The registration form is divided into four tabs:

• General
• Permissions
• Elements
• Sharing

You will be able to save your app by clicking on the Register app button, as long as the required fields have been completed.

#General

App registration - General

• Name: Mandatory field. This is the name of your app.
• Description: Optional field. Here you can provide a description for what your app does.
• Avatar URL: Mandatory field. The avatar URL is the logo that will display next to your app's name, so you'll complete this field with a URL that indicates where your logo is hosted.
• API ID: Mandatory field. This is where you write your API ID. The form will let you know if the name is taken. This field only allows alphanumeric characters, underscores and hyphens, and you must start with a lowercase letter. Please note that this field becomes read-only once the app is created.
• Setup URL: Mandatory field. The setup URL is the form that displays when you install an app for the first time in Hygraph. The form will require some information from the user depending on the characteristics of the app.

Once you've completed all mandatory information, you can move onto the next tab.

#Permissions

This section shows the access details of your app.

App registration - Permissions

• API Permissions: Use these dropdown menus to select permissions for Content API, Schema, and Webhooks.

  • Content API: Grants the app permissions regarding the content. For example, a localization app would need read permissions to access the content to be submitted, then also write permissions to allow the content to be translated.
  • Schema: Grants the app permissions regarding the schema of your project. For example, an app that sets up models in your schema which will be ready to be used after the app installation, would need read / write permissions here.
  • Webhooks: Grants the app permissions regarding your project's webhooks. For example, a newsletter app which sets up a webhook during installation that can later be triggered upon certain action, would require read / write permissions here.
  Setting up your app permissions incorrectly might cause the app not to work when installed.

  API Permissions are only editable when first creating the app. Once the app has been saved for the first time, they can't be changed.

• Client ID: Unique identifier of your app that is used for authentication and authorization. Your Client ID will only display after the app has been saved for the first time.

• Client Secret: Used with the Client ID to resolve and grant access to your app. Your Client Secret will only display after the app has been saved for the first time.

The Client ID and Client secret are the credentials that allow apps to perform actions on behalf of the user.

#Elements

App registration - Elements

• Elements: The Elements section will require different data depending on the element type you select. To start adding elements, click on + Add element:

  • Name: This is where you write the name of your element.

  • API ID: This is where you write your element's API ID.

  • Type: when you create an app, you can have field elements, sidebar elements, or pages.

    • field: Field elements are custom fields that you can add to a model's fields schema.
    • formSidebar: Sidebar elements are custom widgets that you can add to a model's sidebar schema.
    • page: Page adds a section for the app under App views in the Content editor.

  • Features: This dropdown only displays when field is selected as type, and allows you to select features for said field. One or more features can be selected using the dropdown:

    • FieldRenderer: If the feature contains this, it can be rendered for fields.
    • ListRenderer: If the feature contains this, it can be rendered for LIST fields. Click here to learn more about how it works.
    • TableRenderer: If the feature contains this, it can be rendered for Table Cell. Click here to learn more about how it works.

  • Field type: This dropdown only displays when field is selected as type . It allows you to select how the data will be stored, by selecting one of the standard field types from the dropdown menu.

  • URL: Indicates where this element is located in the project, its dedicated URL.

  • Description: It's the description that will appear under your field name in the Add Field / Sidebar Widgets section of the Schema.

  • Config: When you create elements you can have custom settings. This field is completed using a JSON object, which is used to declare extra fields the user wants to render in the field or sidebar form.

App registration - Sharing

After creating an app and saving it for the first time, this section will show the App Sharing read-only field, which contains the URL that you can copy to then share your app.

#Installation

After you've successfully created an app, you will need to install it in order to be able to use it. This guide contains step-by-step information on how to do this.
