File storage systems like Google Drive or MS Sharepoint are one of the most commonly integrated products into SaaS apps. The category is generally dominated by Google and Microsoft, with some specific apps designed for this purpose like Dropbox or [Box.com](http://Box.com).

During our research with dozens of engineers in top SaaS companies, we’ve found that many struggle integrating with them due to the complexity of their APIs. In this article, we’ll explore more about issues with each of them and how to navigate the integrations in a much more efficient way using Integration.app.

## Common Issues on File Storage Integrations

- **App Verification Delays:** The app verification process, especially for Google Drive, is time-intensive and can cause significant delays in deployment.
- **Account Type Differences:** Managing differences between business and personal accounts, particularly for Microsoft 365 or OneDrive, adds complexity.
- **Handling Large Files:** Implementing support for large file sizes, such as multi-page PDFs, audio, and video files, requires long development cycles.
- **Real-Time Updates:** Managing real-time updates versus periodic syncing, particularly for Google Drive and Dropbox, and implementing webhooks or polling, is challenging across all providers.
- **Recursive Structures:** Handling nested file and folder structures and providing an intuitive file picker UI is complex.
- **Efficient File Change Detection:** Detecting file changes efficiently is difficult due to API limitations, especially with Dropbox.
- **Unstructured Data Retrieval:** Retrieving unstructured data from file storage systems like SharePoint and Google Drive requires careful handling.
- **Complete File Listing:** Getting a complete list of all files and folders, as some APIs only return top-level items, is a common issue.
- **Token Rotation:** Handling token rotation during file download adds an extra layer of complexity.

[Integration.app](http://Integration.app) handles the whole integration building experience from managing OAuth, defining common data structures for files, pre-built scenarios and pre-built UI to implement nested file pickers that let you integrate with all top 5 file storage apps in 30 mins or less.

### How Does It Work?

#### Integration Engine

Integration Engine is an API-first and fully customizable service that runs integrations between your app and external apps. It provides abstractions (such as auth, data flows, field mappings), runtime, and state storage for all the integration-related things. This is generally how [Integration.app](http://Integration.app) will help you structure your integration infrastructure in a much simpler way, so you can build File Storage integrations or any category of integrations, much quicker.

You can read more here: [Integration Engine Features](https://integration.app/features/integration-engine).

### List of Scenarios You Can Plug-In to Your Workspace Straight Away


#### 1. Two-way Real-Time Sync of Files

This scenario lets your application sync files from your app to any external application and vice versa. It will do initial import/export of files from your app. Then it will send events when a new file is created/updated or deleted as close to real-time as possible. File fields will be mapped from the schema supported by your application to the application-specific schema.

[Two-way Sync Scenario](https://integration.app/scenarios/6655e496c69030dead8a509d)

#### 2. Create File in Any External Application

This scenario lets your application create a file in any external application. File fields will be mapped from the schema supported by your application to the application-specific schema.

[Create File Scenario](https://integration.app/scenarios/6655e495f36498035913b637)

#### 3. Continuously Import Files to My App

Facing issues with updating your integrations whenever a file changes in your customers’ Dropbox or G Drive? We handle that for you. This scenario lets your application continuously sync files from external applications to your app API. It will handle the initial import of files as well as keep them in sync after a file is created/updated or deleted in the external application. When receiving file data from an external application it will be transformed into the format supported by your app API, allowing your customers to customize that data mapping based on their specific external application setup.

File Storage Integrations: Common Challenges and Solutions with Integration.app


In this guide we will show you how easily you can send Activities from your app to any CRM using [Integration.app](http://Integration.app) while keeping native and white-label experience for your customer.

## Use Case

Your are building Meeting assistant like [Glyphic](https://integration.app/articles/case-studies/glyphic), and your customers want to send meeting summary from your app to their CRM directly from your app. 

So there is two user scenarios present in this use case:

1. Customer see list of available integrations and able to connect any of them
![Frame 1 (2).png](https://integration-app-assets.s3.eu-central-1.amazonaws.com/Frame_1_2_a8967723ca.png)

2. On the Meeting summary page. Once, Integration is connected - export it to CRM as Note and attach it to meeting attendee contact (first one, for simplicity)
![Export Meeting Summary Mockup](https://integration-app-assets.s3.eu-central-1.amazonaws.com/Frame_1_1_bc917b8e87.png)

Let’s implement them! 🙂

## Implementation

First, you need to create an account on [Integration.app](http://integration.app/). This will make you able to access the platform and use Integration.app APIs.

Go to [Apps](https://console.integration.app/w/0/integrations/apps) and enable all applications you wish to Integrate with.

![Frame 629298.png](https://integration-app-assets.s3.eu-central-1.amazonaws.com/Frame_629298_bdf227122b.png)

### Authorizing your customers

Next, follow the [Getting Started Guide](https://console.integration.app/w/0/docs/getting-started/create-connection) to enable your customers to connect their CRM accounts.

To integrate the code, you have two options. You can either download the sample code from the guide in your preferred tech stack, or follow the instructions in the guide to implement it from scratch.

![image 3.png](https://integration-app-assets.s3.eu-central-1.amazonaws.com/image_3_b3ffcdf2f6.png)

### Create Universal Flow

Go to the Flows and create a new Universal Flow. 

Universal Flows let you create multi-step integration logic and works with multiple external applications at once. Our AI-powered engine will automatically generate flow for every application you choose.

![Frame 629301.png](https://integration-app-assets.s3.eu-central-1.amazonaws.com/Frame_629301_17f711fe34.png)

Next on the flow page Click “Manage Integrations” and then “Add Apps” to select the applications you want this flow to work with.

![Frame 629302.png](https://integration-app-assets.s3.eu-central-1.amazonaws.com/Frame_629302_f4a78a456f.png)

### Configure the Trigger

1. Go to the Nodes tab of the Flow
2. Click add Trigger and select “API Trigger” on the right

![Frame 629303 (1).png](https://integration-app-assets.s3.eu-central-1.amazonaws.com/Frame_629303_1_abbaad1c5e.png)

On the right, you will see that the trigger configuration side panel is open. Go to the Input tab and set the input schema, which we will use later to configure the creation of an activity.

Feel free to use the schema you have in your App while setting the Input Schema. We will make it consist of 3 fields: `title`, `body`, and `attendeeEmail`.

![InputSchema.png](https://integration-app-assets.s3.eu-central-1.amazonaws.com/Input_Schema_2c88f9f551.png)

### Find Contact in the CRM

Now we need to find Contact in CRM by email, so we can use it's ID later to relate Activity to it. 
Click on "Add Node" and then select "Lookup Data Record" from the nodes list.  

![Frame 629306.png](https://integration-app-assets.s3.eu-central-1.amazonaws.com/Frame_629306_28ea49214b.png)

With Data Operations Nodes  you no longer need to worry about the specifics of each app's API. Just set Data Model to Contacts in the Node sidebar, that's how Integration.app will know what object type you want to work with and will automatically map it for every application.

![Frame 629307.png](https://integration-app-assets.s3.eu-central-1.amazonaws.com/Frame_629307_387b1759fe.png)

Next, setup Lookup Query to search contact by primary email using Attendee Email that we added to API Trigger schema:

![image 21.png](https://integration-app-assets.s3.eu-central-1.amazonaws.com/image_21_c5de08e868.png)

With such configuration Integration.app will automatically generate the proper query for every App and return [Data Record](https://console.integration.app/w/0/docs/concepts/connectors/data/data-records) containing contact data. 

### Create Activity in the CRM

Click on `plus` button bellow `Lookup Data Record` node and then select `Create Data Record` from the nodes list. 
In the node configuration sidebar set the Data Model to "Notes" (choose "Activities", "Tasks", or "Meeting" if you have a different need) similar to what we did in the previous step.

Next, we will fill the data we want to create activity with. But since, we don't know exact CRM fields at this moment (because there is no customer CRM connection yet) - you will see unified fields from Integration.app Data Model available below. You can setup them using output of API Trigger and Lookup Contact node, Integration.app will take care of mapping this fields to exact fields for every CRM if they exist there.

The fields you see - is the most common fields across apps we support for the selected Data Model. When customer connects an CRM we trasform this mapping to the exact CRM fields.

Done! You can test the Integration using the Test tab and add it to your application UI. 

## Add to your App

Now you can add code to your App to run the Flow we’ve just build. Below you can see a sample snippet that may be used to run it. Just fill the input with your data and set `flowKey` and `integrationKey` to once that are needed.

```jsx
await integrationApp
  .flowInstance({
    flowKey: 'create-activities', // Flow key you've set, while creating Universal Flow
    integrationKey: 'hubspot', // Integration you wish to run an integration
    autoCreate: true,
  })
  .run({
    input: {
			title: "My Meeting title",
			body: "Meeting summary",
			crmContactId: 104
		}
  })
```

You can read more about Customer Flow Instances and how to run them [here](https://console.integration.app/w/0/docs/concepts/flows/api#running-flows) 

Congrats! You’ve implemented sending of Activities from your app to multiple of CRM!

You can continue improving this integration by:

1. Making customers able to customize the Field Mapping
2. Making customers able to select type of Activity to Create
3. Implementing backwards sync of Activities

In this guide we will show you how easily you can send Activities from your app to any CRM using Integration.app while keeping native and white-label experience for your customer.
