App Manifest

The manifest.json file contains information such as the platform version used by a product, locations on the product UI where an app can be rendered (for front-end apps), dependent packages used by the app, SMI functions that can be invoked from an app’s front-end component, events and the corresponding callbacks (for serverless apps), and the Node.js and FDK versions used to build, test, validate, and pack the app. For apps built using FDK version 9.0.0 or later, if the app is expected to make third-party HTTP calls, manifest.json lists the configured request templates that the app invokes to construct and send secure HTTP requests to the third-party domains. For apps built using an FDK version prior to 9.0.0 (platform version 2.2), manifest.json whitelists all the third-party domains with which the app can interact. This section details the various attributes of the manifest.json file.

Attributes

Attribute Name Date Type Description
platform-version string Specifics the platform version used to build the app, auto-generated when the app files are created. The version information is used to ensure backward compatibility when a new platform version is released.
product
Mandatory		 object Associates a Freshworks product with the information that is necessary to render the app on the specified product.
(Child attribute: freshworks_crm)
freshworks_crm
Mandatory		 object Specifies information that is necessary to render the app on the Freshsales Suite UI.
(Child attribute: location or events (for severless apps))
location
Mandatory		 object Specifies the locations on the product(s) UI, where the app is to be rendered.
For more information, see Placeholders
Attributes: url, icon
url
Mandatory		 string Specifies the relative path from the app project directory to the HTML file based on which the app is rendered. The contents of the HTML file are used to render the app in an IFrame at the specified location.
Default value: template.html (file in the app directory)
icon
Mandatory		 string Specifies the relative path from the app project directory to an image file (in SVG format). The image is used as the app’s icon when the app is rendered on the UI. Ensure that the resolution of the image is 64 x 64 pixels.
Default value: icon.svg (file in the app directory)
requests
Valid only for apps built with platform version 2.3 		object Specifies the configured request templates that the app code uses, for a product, in the following format. Copied Copy

…
},
  "<requestTemplateName1>": {}
    …
}

Notes:
  • <requestTemplateName> must be the same as that configured in config/requests.json.
  • Possible values of <option-name> are maxAttempts, retryDelay, and isOAuth. If an option is specified in both manifest.json and config/requests.json, the option value specified in manifest.json takes precedence.
events

    }
  }

    }
  }
EXPAND ↓ Child attribute:
timeout (integer): Time in seconds beyond which the app execution times out, if the SMI function does not return a valid response to the front-end component. You can specify an appropriate timeout value based on the SMI function.
Valid values : 5, 10, 15, and 20
For more information, see Server Method Invocation.
engines object Specifies the Node.js version and FDK version that are used to build the app. FDK auto-populates this value.
Creating an app: If you use FDK 7.0.0 or later versions to create an app, the engines attribute is available by default as part of the manifest.json file.
Migrating an app: If you have an existing app that is built using FDK 6.x.x or an earlier version, ensure to,
  1. Install the latest FDK version.
  2. Run fdk validate to migrate the app to the latest FDK version. As part of this process, the FDK updates the engines attribute.
  3. Retest the app.
Child attributes:
node (string): Specifies the Node.js version on which the app is built (in case of new apps) or successfully validated (in case of apps built using FDK 6.x.x or earlier versions and migrated to the latest FDK).
fdk (string): Specifies the FDK version that is used to build, test, validate, and pack the app.
whitelisted-domains
Mandatory

Valid only for apps built with platform version 2.2		 array of string Contains the third-party domains to be whitelisted for making secure HTTP calls using the Request method.
Notes:
  • If the requisite domains are not whitelisted, the fdk run command displays an error message This domain has not been whitelisted.
  • To use iparams to construct the whitelisted-domains values, use the following format:
    1
    		"whitelisted-domains": ["<%= iparam.url %>"]
  • Ensure that the whitelisted-domains array values:
    • For apps that access a Freshsales Suite account URL, through the request method, ensure to whitelist https://<sub-domain>.myfreshworks.com and https://<sub-domain>.freshworks.com.
    • Do not contain an IP address or multiple subdomains.
    • Do not contain the path to the resource.
    • Use HTTPS, if iparams are not used to construct the whitelisted-domains values.
    • Are not URLs to a localhost.
