Mustache Variables

Mustache Variables

Integrations Hub for Jira allows custom variables that can be used when generating an integration request. Under the hood, we're using JSONPath and Mustache to extract and substitute variables for integration request.

It's currently possible to substitute the following:

  • Request URL

  • Request headers

  • Request body

  • Request Authorization

General usage

Variables are accessed by using the curly braces notation of Mustache. 

{{variable_name}} or for an object, the dot notated getter name without the "get".

Example: {{my_object.name}} . For the value of the getName() of the my_object variable

Value variables (Primitives/Strings ie.)

{{variable}} - Substitutes the variable value

Objects

{{object_name.user.name}} - Substitutes the object_name getUser().getName() value

Collections

Iterate through lists using the following Mustache pattern:

{{#title}}{{.}}{{/title}}

See Manage Arrays for further info

Formatting dates

Date objects can be formatted by using the following syntax. {{#date}}{{#format}}java_date_format_pattern{{/format}}{{/date}}

Example:

{{#issue.updated}} {{#format}} yyyy-MM-dd {{/format}} {{/issue.updated}} - Will format issue updated date. (since v.3.8.0)

Quick Formats (since v 4.4.0)

{{now.yearMonthDay}} = YYYY-MM-DD

{{now.monthDayYear}} = MM/DD/YYYY

{{now.monthDayYear2}} = MM/DD/YY

{{now.dayMonthYear}} = DD-MM-YYYY



Default variables

See the Java impl of the Comment interface here https://docs.atlassian.com/software/jira/docs/api/7.1.5/com/atlassian/jira/issue/comments/Comment.html each method is accessible using dot notation without the get. example getId() is accessible using {{comments.latest.id}}

Get the latest or first use:

  • {{attachments.first}}

  • {{attachments.last}} same as latest

  • {{attachments.latest}}

  • content type String base64encoded, ex {{attachments.last.content}}

.asJson

You can use the .asJson method on any variable to retrieve the complete JSON object that the variable represents.

For example, if you have a data object like this: { "key": "hej", "more": {"extra": "abc","ex":"efg"}}, then using {{more.asJson}} with mustache notation will result in a JSON format containing {"extra": "abc","ex":"efg"}}.

This feature is useful when you need to extract subsets or entire chains of JSON responses.

This can be extra useful when filter incoming responses. Incoming Webhooks
