FlutterFlow and GoToWebinar integration: Step-by-Step Guide 2024

   

• FlutterFlow Account: Make sure you have a FlutterFlow account.
• GoToWebinar Account: Ensure you have an active GoToWebinar subscription.
• API Access: You’ll need to generate API keys for GoToWebinar.
• Basic Programming Knowledge: Familiarity with FlutterFlow and how APIs work will be helpful.

   

• Navigate to GoTo Developer Center: Go to the GoTo Developer Center.
• Create an App:
• Click on "My Apps" and then "Create a New App".
• Fill in the required information, such as the application name, description, etc.
• Choose the appropriate permissions. For basic webinar functionalities, you might need "User", "Webinar", and "WebinarsView".
• After creating the app, you'll receive a Client ID and Client Secret.

   

• Authorization URL: Construct the authorization URL to obtain an authorization code.

https://api.getgo.com/oauth/v2/authorize?client_id=YOUR_CLIENT_ID&response_type=code&redirect_uri=YOUR_REDIRECT\_URI

• Obtain Authorization Code: When a user accesses this URL, they'll be prompted to log in to GoToWebinar and authorize your application. Upon success, they'll be redirected to the specified redirect\_uri with an authorization code appended.
• Exchange Code for Access Token:
• Use the authorization code to request an access token.
• Make a POST request to:

https://api.getgo.com/oauth/v2/token

• Include these parameters in the body:

      

         
grant_type: authorization_code
         
code: the authorization code received
         
redirect\_uri: your redirect URI
         
client\_id: your client ID
         
client\_secret: your client secret
      

• The response will include an access\_token which is used to make API calls.

   

• Set Up API Endpoint:
• In FlutterFlow, navigate to the "Backend" section.
• Click on "API Calls" and then "Add API".
• Configure the API with required details:

      

         
Name: e.g., GoToWebinar Registration
         
Endpoint URL: The specific GoToWebinar endpoint URL (e.g., `https://api.getgo.com/G2W/rest/v2/organizers/{organizerKey}/webinars/{webinarKey}/registrants`)
      

• Headers:
• Authorization: Bearer YOUR_ACCESS_TOKEN
• HTTP Method: POST
• Body: (JSON format depending on the API, e.g., for registration)

 
         {
            "firstName": "John",
            "lastName": "Doe",
            "email": "[email protected]"
         }

   

• Design Registration Form:
• Use widgets like `TextFormField` for user inputs (First Name, Last Name, Email, etc.)
• Utilize a `Button` widget to trigger the API call when the user submits the registration form.

   

• Add API Request to Button:
• Select the button and navigate to "Actions".
• Add a new action, choose "API Call", and select the previously set GoToWebinar API.
• Map the user input fields to the API request body.
• Handle API Response:
• Customize UI flow based on success or failure responses.
• Show a success message or handle errors accordingly.

   

• Run the App: Deploy and run the FlutterFlow app on a simulator or physical device.
• Test the Workflow: Ensure the registration process is functioning by testing with valid input data.
• Debug: If errors occur, utilize FlutterFlow’s debugging tools and review GoToWebinar API documentation for troubleshooting.

   

• Deploy the App: Once fully tested, deploy your FlutterFlow app.
• Monitor API Usage: Regularly check GoToWebinar API usage and error logs for any issues.
• Update API Tokens: Access tokens may expire; ensure you have a mechanism to refresh tokens.
