Now you have an understanding of how Apps in the Messenger work, you'll need to provide the necessary details in your Messenger Framework page in the Developer Hub to start building your app.
You'll first need to to specify where your app will work in Intercom:
You can select a combination of the three. The selection boxes look like so:
If a particular location is not selected, your app will not appear when you go to add the app in that location.
You'll need to provide the URLs where we'll send the relevant POST requests to. These are as follows:
The URL where we’ll POST all initialize-card requests sent by the framework. More on the initialize flow through this link.
The URL where we'll POST all configure-card requests sent by the framework. If your app doesn't require any information from teammates when it’s being added then please leave this blank. More on the configure flow through this link.
The URL where we'll POST all submit-card requests sent by the framework. More on the submit flow through this link.
The URL where we'll POST all submit_sheet requests sent by the framework. More on the sheets flow through this link.
You can always change the values you enter above at a later date. The input boxes look like so:
This step is only necessary if you plan to publish your app to the Intercom App Store
Apps in the Messenger must implement OAuth when they are to be publicly listed, and have to be installed via the Intercom App Store. To achieve this, you'll first need to set up the standard OAuth authentication flow.
Then, you'll need to provide the following URLs on your App store listing page. Under Installation, select Directly via Intercom app store to bring up the input boxes to insert your URLs:
The URL pointing to your external website/app, kicking off the OAuth 2.0 flow for installing your app via the App Store. More on Setting up OAuth, and what this URL should look like, through this link.
If you supply an uninstall URL we'll send a POST request to this URL when a teammate uninstalls your App via the App Store. You can use this to handle any cleanup or de-authorization you need to.
Once you've gone through the OAuth flow to receive a code from Intercom (which you can swap for an Access Token), you can optionally have the user authenticate with your product. Effectively, this links Intercom and the end users account with your own product.
Order of Authentication
You must have the user authenticate through the Intercom OAuth flow before you prompt them to authenticate with your own app. This is for security measures and to ensure a clean process on your side, whereby you can rest assured that they have approved access to their data and have installed with Intercom successfully.
The final step is to send the user who is installing your app back to the Intercom App Store. You must redirect back to the App Store at the end in order to post back if the flow was successful or not:
If Intercom OAuth and (optionally) OAuth to your product are both successful you should redirect the user to
This URL will bring them back to the App Store and will display a success message.
If either Intercom or your product's OAuth was unsuccessful you should redirect the user to
https://app.intercom.io/appstore/redirect?error_message=<your error message>
You can fill in the error message parameter with any error information you have.
