Trigger bitbucket on pull requyest comment

[Kamil Walo]

I am trying to set up automated pipeline triggers in Bitbucket by commenting on a pull request. The goal is to write a specific comment, e.g., "//deploy" on bitbucket comment, and have it trigger a pipeline on bitbucket.

Similar functionality exists in GitHub Actions and Azure DevOps — they support triggering workflows or pipelines via commenting (for example, through webhooks or built-in integrations).

My question is: is there a way to achieve this in Bitbucket? I know that Bitbucket supports webhooks that can be sent when a new comment is created. But how can I leverage this webhook to trigger a pipeline automatically — specifically, how can I configure Bitbucket to send the webhook into itself or otherwise trigger the pipeline based on a comment?

I’ve tried using the API endpoint like this:

https://api.bitbucket.org/2.0/repositories/kamil/test/pipelines/?target=%7B%22target%22%3A%7B%22ref_type%22%3A%22branch%22%2C%22type%22%3A%22pipeline_ref_target%22%2C%22ref_name%22%3A%22main%22%7D%7D

but it doesn’t work

this one does work but I cannot add body to webhook on 

Repository -> repository settings -> Webhooks

curl -X POST  \

  --header 'Authorization: Bearer <token>' \

  --header 'Content-Type: application/json' \

https://api.bitbucket.org/2.0/repositories/kamilwalooo/test/pipelines/\

  -d '

  {

    "target": {

      "ref_type": "branch",

      "type": "pipeline_ref_target",

      "ref_name": "main"

    }

  }'

Any guidance on how to set this up? Thanks!
