Trello is a project management tool used to track team projects and ongoing tasks, show who they are assigned to, and get detailed progress towards completion. Trello is easy to integrate with the other software .

Trello authenticates API requests from Hevo to access your account data with HTTP Basic authentication.


Obtaining the API Key and Secret Token

The credentials (API key and secret token) that you generate in Trello do not expire. Therefore, you can use your existing credentials or create new ones to authenticate Hevo on your Trello account.

Note: You must log in as an Admin user to perform these steps.

To obtain the credentials:

  1. Log in to your Trello account.

  2. Visit Developers API Keys to obtain the API Key and Secret Token.

  3. In the page that appears, do the following:

    1. Copy the Personal Key and save it securely like any other password. Use this as the API Key while configuring your Hevo Pipeline.

      Copy API key

    2. Under Personal Key, click Token.


  4. In the Server Token page, scroll down to the bottom, and click Allow.


  5. In the page that appears, copy the token and save it securely like any other password. Use this as the Secret Token while configuring your Hevo Pipeline.


Configuring Trello as a Source

Perform the following steps to configure Trello as the Source in your Pipeline:

  1. Click PIPELINES in the Navigation Bar.

  2. Click + CREATE in the Pipelines List View.

  3. In the Select Source Type page, select Trello.

  4. In the Configure your Trello Source page, specify the following:


    • Pipeline Name: A unique name for the Pipeline, not exceeding 255 characters.

    • API Key: The API key that you obtained above.

    • Secret Token: The secret token that you obtained above.

  5. Click TEST & CONTINUE.

  6. Proceed to configuring the data ingestion and setting up the Destination.

Data Replication

For Teams Created Default Ingestion Frequency Minimum Ingestion Frequency Maximum Ingestion Frequency Custom Frequency Range (in Hrs)
Before Release 2.21 1 Hr 1 Hr 24 Hrs 1-24
After Release 2.21 6 Hrs 30 Mins 24 Hrs 1-24

Note: The custom frequency must be set in hours as an integer value. For example, 1, 2, or 3 but not 1.5 or 1.75.

  • Historical Data: In the first run of the Pipeline, Hevo ingests all the existing data for the selected objects from your Trello account and loads it to the Destination.

  • Incremental Data: Once the historical load is complete, all new and updated records for the Actions and Cards objects are ingested as per the ingestion frequency. The remaining objects are ingested in Full Load mode.

Source Considerations

  • Pagination: An API response for each Trello object fetches one page with up to 1000 records.

  • Rate Limit: Trello imposes a limit of 30 API calls per second for each API key and 10 API calls per second for each server token, except for the Boards object, which has a limit of six API calls per minute. If the limit is exceeded, Hevo defers the ingestion till the limits reset.

Schema and Primary Keys

Hevo uses the following schema to upload the records in the Destination database:

Data Model

The following is the list of tables (objects) that are created at the Destination when you run the Pipeline:

Object Mode Description
Actions Incremental Contains the details of all the actions associated with Trello entities. For example, Trello action addAttachmentToCard means that attachment was added to a card.
Boards Full Contains the details of all the projects, teams, or workflows in an organized order.
Boards allows you to organize your tasks which helps you to collaborate with your colleagues.
Cards Incremental Contains the details of all the tasks and ideas within a board.
Checklists Full Contains the list of all the subtasks within a card.
Labels Full Contains the details of the color tags used to organize cards within your Trello account.
It is used to track which types of activities your team is spending time on.
Lists Full Contains the details of all the cards, to keep track of their progress.
A card is a collection of ideas, things to remember, or different stages of a workflow.
Members Full Contains the details of all the users who are given access to workspaces, projects, and tasks in your Trello account.


  • Hevo does not capture information for records deleted in the Source objects.

  • Hevo does not provide you with the option to select the historical sync duration for loading historical data. All the historical data in your Harvest account is loaded.
