## How To Create Value With Trello Data

Teams connect Trello to their data warehouse to build dashboards and generate value for their business. Let’s dig into the capabilities Trello exposes via their API, outline insights you can build with the data, and summarize the most common analytics environments teams are using to process their Trello data.

### Extract: What Data Can You Extract From The Trello API?

Trello is a productivity tool used for managing workflows, projects and tasks.

To help clients power downstream analytics, Trello offers an application programming interface (API) for clients to extract data on business entities. Here are a few example entities you can extract from the API.

- Organizations
- Boards
- Actions
- Cards
- Checklists
- Labels
- Lists
- Members
- Etc.

You can visit [the Trello API documentation](https://developer.atlassian.com/cloud/trello/rest/) to explore the entire catalog of available API resources and the complete schema definition for each. As an example, here are some of the details for the boards endpoint in the Trello API documentation.

As you think about the data you will need for analytics, don’t forget that Portable offers no-code integrations to other similar applications like [Asana](https://portable.io/connectors/asana), [Jira](https://portable.io/connectors/jira), and [ClickUp](https://portable.io/connectors/clickup) that can be useful for comparison purposes.

Regardless of the SaaS solution you use, it’s important to find a productivity tool with robust data available for analytics.

### Load: Which Destinations Are Best For A Trello ETL Pipeline?

To turn raw data from Trello into dashboards, most companies centralize information into a data warehouse or data lake. For Portable clients, the most common ETL pipelines are:

1. [Trello to Snowflake Integration](https://portable.io/connectors/trello/snowflake)
2. [Trello to Google BigQuery Integration](https://portable.io/connectors/trello/bigquery)
3. [Trello to Amazon Redshift Integration](https://portable.io/connectors/trello/redshift)
4. [Trello to PostgreSQL Integration](https://portable.io/connectors/trello/postgresql)

![Common Data Warehouses](https://drive.google.com/uc?id=1dwU6fS5EI2GNuhrY_W6rgEv7ME2UMvLF)

Once you have a destination to load the data, it’s common to combine Trello data with information from other enterprise applications like Jira, Mailchimp, HubSpot, Zendesk, and LinkedIn.
 
From there, you can build cross-functional dashboards in a visualization tool like Power BI, Tableau, Looker, or Retool.

### Develop: Which Dashboards Should You Build With Trello Data?

Now that you have identified the data you want to extract, the next step is to plan out the dashboards you can build with the data.
 
As a process, you want to consume raw data, overlay SQL logic, and build a dashboard to either 1) increase revenue or 2) decrease costs.
 
Here are three project analytics dashboards you should consider as a starting point.

1. **Open Tasks (By Assignee)** - If your team is analyzing tasks, it's easy to build a quick summary of open tasks for each assignee to help to keep everyone in the loop.
2. **Overdue Tasks (By Project)** - Every once in a while, tasks are delayed. Setting up alerts or notifications when tasks are overdue within a project can help your team stay on track.
3. **Average Time To Complete Tasks (By Month Created)** - For operational teams and support teams, the completion time for tasks can be a great metric to help streamline processes. By showing trend data of the average time to complete tasks, you can better understand how your operational initiatives are working and consistently strive to support clients in real time.

Beyond the dashboards above, replicating Trello data into your cloud data warehouse can unlock a wide array of opportunities to power analytics, automate workflows, and develop products. The use cases are endless.

Now that we have a clear sense of the insights we can create, let’s compare the process of developing a custom Trello integration with the benefits of using a no-code ETL solution like Portable.

## Method 1: Building A Custom Trello ETL Pipeline

To build your own Trello integration, there are three steps:
 
1) Navigate the Trello API documentation
2) Make your first API request
3) Turn an API request into a complete data pipeline
 
Let’s walk through the process in more detail.

### How To Interpret Trello’s API Documentation

When reading API documentation, there are a handful of key concepts to consider.

#### Authentication

There are many common authentication mechanisms. OAuth 2.0 (Auth Code and Client Credentials), API Keys, JWT Tokens, Personal Access Tokens, Basic Authentication, etc. For Trello, it’s important to identify the authentication mechanism and how best to incorporate the necessary credentials into your API requests.

Trello uses API keys and tokens for authentication. In addition to the authentication parameters, you will need your organization ID from Trello to make API requests. Your organization ID can be found in the URL when you visit Trello.

#### Resources

It’s important to identify the Trello API endpoints you want to use for analytics. Most APIs offer GET, POST, PUT, and DELETE methods; however, for analytics, GET requests are typically the most useful. At times, POST requests can be used to extract data as well.
 
For Trello, the boards endpoint is a great place to get started.

#### Request Parameters

For each API endpoint, you would like to use for analytics, you need to understand the method (GET, POST, PUT, or DELETE) and the URL, but there are other considerations to take into account as well. You should look out for pagination mechanics, query parameters, and parameters that are added to the request path.

Some API endpoints offer pagination. For instance, when listing members of an enterprise, the endpoint uses startIndex and count parameters for pagination.

![Trello Pagination Overview](https://drive.google.com/uc?id=1kuyvbj3LFp7hocG9PbKgFgrgnOXoAwAx)

Some API endpoints require unique identifiers from a previous API response to be included in the URL path.

For instance, to get all members in an enterprise, you need an enterprise ID that is returned from another endpoint.

### How Do You Call The Trello API? (Tutorial)

1. Follow the instructions above to read the Trello API documentation
2. Identify and collect your credentials for authentication
3. Pick the API resource you want to pull data from
4. Configure the necessary parameters, method, and URL to make your first request (Either with curl or Postman)
5. Add your credentials and make your first API call. Here is an example request using curl (without real credentials):

```
curl --request GET \
  --url 'https://api.trello.com/1/organizations/{id}/boards?key=APIKey&token=APIToken' \
  --header 'Accept: application/json'
```

### How Do You Maintain A Custom Trello ETL Pipeline?

Making a call to the Trello API is just the beginning of maintaining a complete custom ETL pipeline. 
 
Here is a getting started guide to building a production-grade pipeline for Trello:

- For each API endpoint, define schemas (which fields exist and the type for each)
- Process the API response and parse the data (typically parsing JSON or XML)
- Handle and replicate nested objects and custom fields
- Identify which fields are primary keys and which keys are required vs. optional
- Version control your changes in a git-based workflow (using GitHub, GitLab, etc.)
- Handle code dependencies in your toolchain and the upgrades that come with each
- Monitor the health of the upstream API, and - when things go wrong - troubleshoot via the status page, reach out to support, and open tickets
- Handle error codes (HTTP error codes like 400s, 500s, etc.)
- Manage and respect rate limits imposed by the server

We won’t go into detail on all of the items above, but rate limits are a great example of the complexity found in a production-grade data pipeline.
 
For rate limits, Trello limits the number of requests that can be made by each API key (300 for every 10 seconds), but also restricts the number of requests that can be made by each token (100 for every 10 seconds).

![Trello Rate Limits](https://drive.google.com/uc?id=1V2okeW-ZwlvjjxxKje2nit8fjwWFN22F)

If you don’t respect rate limits, and if you can’t handle server responses (like 429 errors with a Retry-After header), your pipeline can break, and analytics can become out-of-date.

### What Are The Drawbacks Of Building A Trello ETL Pipeline Yourself?

You can probably tell at this point that there is a lot of work that goes into building and maintaining an ETL pipeline from Trello to your data warehouse.
 
If you want less development work,  faster insights, and no ongoing responsibilities, you should consider a cloud-hosted ETL solution.
