Configuring a bitbucket repository to "activate" pipelines - bitbucket-api

Question

I have multiple repositories in a BitBucket project.
I wish to automatically create a bitbucket repository, and enable pipelines (setting the pipeline configuration should be easy, with pushing a bitbucket-pipelines.yml file).
How can I do it using the REST API?

Answer 1

The other answer's "enable pipelines" request did not work for me.
This is what worked:
curl -X PUT -is -u '<username>:<password>' -H 'Content-Type: application/json' \
https://api.bitbucket.org/2.0/repositories/<username>/<slug>/pipelines_config \
-d '{
"enabled": true
}'

Answer 2

You can create a repository with the BitBucket REST API.
$ curl -X POST -H "Content-Type: application/json" -d '{
"scm": "git",
"project": {
"key": "Foo"
}
}' https://api.bitbucket.org/2.0/repositories/<username>/<repo_slug>
Push your bitbucket-pipelines.yml to your created repo.
curl https://api.bitbucket.org/2.0/repositories/<username>/<slug>/src \
-F /bitbucket-pipelines.yml=#bitbucket-pipelines.yml
Then enable pipeline for your project
curl -X PUT -is -u '<username>:<password>' -H 'Content-Type: application/json' \
https://api.bitbucket.org/2.0/repositories/<username>/<repo_slug> \
-d '{
"enabled": true,
"type": "repository_pipelines_configuration"
}'
Finally, you can trigger a pipeline for the branch like so.
$ curl -X POST -is -u <username>:<password> \
-H 'Content-Type: application/json' \
https://api.bitbucket.org/2.0/repositories/<username>/<slug>/pipelines/ \
-d '
{
"target": {
"ref_type": "branch",
"type": "pipeline_ref_target",
"ref_name": "<branch_name>"
}
}'
