How to integrate FlutterFlow with Backblaze B2?

 

Step-by-Step Guide on How to Integrate FlutterFlow with Backblaze B2

 

Prerequisites

 
  • Make sure you have a FlutterFlow account.
  • Have a Backblaze B2 account with at least one created bucket.
  • Basic understanding of API integration.

Step 1: Set Up Backblaze B2

 
  • Sign in to your Backblaze B2 account.
  • Navigate to the Buckets page.
  • Create a new bucket or choose an existing one.
  • Access the App Keys section.
  • Create a new App Key.
  • Note down the Key ID and Application Key as these will be needed later.

Step 2: Create a FlutterFlow Project

 
  • Sign in to your FlutterFlow account.
  • Create or open a project where you intend to integrate Backblaze B2.

Step 3: Set Up FlutterFlow HTTP Requests

 
  • In FlutterFlow, navigate to the API Calls from the Settings/Integrations menu.
  • Click on Add API Call.

Step 4: Configure Authorization Header

 
  • Name the API Call (e.g., BackblazeAuth).
  • Authorization URL: https://api.backblazeb2.com/b2api/v2/b2_authorize_account.
  • Add Headers:
    • Header Name: Authorization
    • Value: Basic {Base64 encoded Key ID:Application Key}
    • Encode your Key ID and Application Key in the format KeyID:ApplicationKey using Base64 encoding.
    • Example in Python: 
      import base64
key_id = "your_key\_id"
application_key = "your_application\_key"
credentials = f"{key_id}:{application_key}"
encoded\_credentials = base64.b64encode(credentials.encode()).decode()
print(encoded\_credentials)

Step 5: Parse Authorization Response

 
  • Add an Output Parameter to store the response:
    • Parameter Name: apiUrl
    • Type: String
    • Response Path: apiUrl
  • Another Output Parameter:
    • Parameter Name: authorizationToken
    • Type: String
    • Response Path: authorizationToken

Step 6: Configure Further API Calls

 
  • Once authorized, you will need to interact with other B2 API endpoints.
  • For example, to upload a file:
  • Go back to your API Calls settings.
  • Add API Call and name it (e.g., UploadFile).
  • Endpoint URL: Concatenation of apiUrl value from previous response and b2_get_upload\_url.
  • Make sure to replace apiUrl properly.

Step 7: Add Upload File Endpoint Details

 
  • Add Headers:
    • Authorization: Value should dynamically use authorizationToken from the first call.
    • Example: Bearer {authorizationToken}
  • Request Method: POST
  • Request Body:
    • Field Name: file
    • Type: File
    • JSON Path: Leave empty

Step 8: Implement API Calls in Your FlutterFlow App

 
  • Use the API Call widget or action to trigger these calls in your FlutterFlow app.
  • Make sure to handle:
    • Initial Authorization
    • Subsequent Data Fetching & Uploading

Step 9: Handle Responses

 
  • Based on the response from Backblaze B2, update your UI or handle errors appropriately.
  • Use FlutterFlow's inherent capabilities to parse the API responses and display/upload accordingly.

Step 10: Test Your Integration

 
  • Debug and test each step thoroughly to ensure that the integration correctly handles:
    • Authorization
    • File Uploads
    • Error Handling

Conclusion

 

By following these detailed steps, you can successfully integrate FlutterFlow with Backblaze B2. This setup not only allows uploading of files to your Backblaze B2 bucket but also ensures secure handling of authorization tokens. Make sure you rigorously test your integration to cover all potential edge cases.
