feat: Add default result expressions for selected connectors by jan-ladleif · Pull Request #6655 · camunda/connectors

jan-ladleif · 2026-03-12T05:50:57Z

Description

This PR adds default values for resultExpression using the defaultResultExpression annotation for selected connectors. The default values were chosen based on the actual data a user should expect when using them. As discussed in the team (https://github.com/camunda/team-connectors/issues/1183), using FEEL comments some concrete examples were also indicated.

The PR covers the following connectors and adds the following defaults:

`http/polling`

{
  myResponseBody: response.body
  // Use FEEL to extract values, e.g.,:
  // myUserId: response.body.post.userId
}

`http/rest`

{
  myResponseBody: response.body
  // Use FEEL to extract values, e.g.,:
  // myUserId: response.body.post.userId
}

`webhook`

{
  myRequestBody: request.body
  // Use FEEL to extract values, e.g.,:
  // myMessage: request.body.message
}

`slack` (inbound)

{
  myRequestBody: request.body
  // Use FEEL to extract values, e.g.,:
  // myUserId: request.body.event.user
}

`slack` (outbound)

{
  myResponse: response
  // Use FEEL to extract values depending on message
  // type, e.g.,: myMessage: response.message.text
}

Checklist

Backport labels are added if these code changes should be backported. No backport label is added to the latest
release, as this branch will be rebased onto main before the next release. Example backport labels:
- backport stable/8.8: for changes that should be included in the next 8.8.x release.
- or backport release-8.8.7: for changes that should be included in the specific release 8.8.7, and this
  release has already been created. The release branch will be merged back into stable/8.8 later, so the change
  will be included in future 8.8.x releases as well.
Tests/Integration tests for the changes have been added if applicable.

This reverts commit 6805b2e.

Pull request overview

This PR adds default resultExpression values (via defaultResultExpression) to several connectors so users get meaningful output mappings by default in generated element templates.

Changes:

Added defaultResultExpression to Webhook, Slack (inbound/outbound), HTTP REST, and HTTP Polling connectors and bumped template versions.
Updated corresponding element templates (standard + hybrid) to include a default resultExpression value and incremented versions.
Added version-pinned copies of previous element template versions under element-templates/versioned/.

Not sure if the build failures are due to the changes --- would be happy to jump in a call and look through the pipelines if that is something I can fix, but could not find anything concrete by myself.

I re-started the tests, you have to do that sometimes, sadly :( The failures are not related to your PR
