Benefits of Using OData Feeds with CommCare

Setting Up OData Feeds in CommCare

Step 1: Enable OData Feed

  1. Log in to your CommCareHQ account.

  2. Navigate to the project space where you want to enable the OData feed.

  3. Go to Data > Export Data.

  4. Choose the type of data you want to create an OData feed for (e.g., Forms or Cases).

  5. Click on the + Create OData Feed button next to the relevant data export.

Step 2: Configure OData Feed Settings

  1. Specify a name for your OData feed.

  2. Choose the data items you want to include in your feed.

  3. Configure any additional settings, such as filters for the data.

  4. Save your OData feed configuration.

Step 3: Accessing Your OData Feed

  1. After saving, you will be provided with an OData URL. This URL is used to access your OData feed.

  2. Ensure you have the necessary authentication details, as OData feeds require authentication to access.

Repeat Groups

If setting up an OData Feed for a form that contains repeat groups, you will also need to reference the additional feeds created for that repeat group data if it is of interest. Each repeat group will have its own OData URL.

When querying Repeat Group OData URLs, the limit and offset parameters operate at the form level, meaning limit=1 will return all responses within a repeat group for one form.
