A custom attribute is a field that changes from one credential to the next, such as a grade, a score or a completion date. Each one gets a merge tag, for example [custom_grade]. Go to Settings → Attributes.
The Attributes page with four attributes and their merge tags
Only administrators can manage attributes. Custom attributes depend on your plan.

​
How it works

  1. Create an attribute. It gets a merge tag made from its name, like [custom_grade].
  2. Give each credential a value. Fill it in as a column of your spreadsheet, or in the form, when you issue credentials. You can also change it when you edit a credential.
  3. Use it in designs and emails. Put the merge tag in a design or an email template. It is replaced with each credential’s value.

With the API, send attribute values in custom_attributes, with the merge tag name as the key, for example "custom_grade": "A".
