How do I trigger a bitbucket pipeline using API request?

Ishan Roy I'm New Here Aug 19, 2021

I am trying to trigger a bitbucket pipeline using the api endpoint, but I am getting the following response: 
"error": {
"message": "Bad request",
"detail": "bitbucket-pipelines.yml not found.",
"data": {
"key": "result-service.pipeline.yml-not-found",
"arguments": {}

This is the request that I am using. I have verified and this branch has the pipeline and I am able to trigger it manually from pipelines section of the repo.

curl -X POST -is -u username:password \
-H 'Content-Type: application/json' \{workspace}/{repo_slug}/pipelines/ \
-d '
"target": {
"ref_type": "branch",
"type": "pipeline_ref_target",
"ref_name": "branchname"
"variables": [
"key": "key1",
"value": "value1"
"key": "key2",
"value": "value2"

Hi @Ishan Roy and welcome to the community.

The data you need to send with the request depends on the type of the pipeline you want to trigger.

The documentation below has some examples:

Is the pipeline you want to trigger defined as follows


in the bitbucket-pipelines.yml file of this branch? Or is it perhaps a custom pipeline? In case it's a custom pipeline, you'll need to include some additional fields in the request (you can check the examples in the doc).

We'd need to know in which section of your bitbucket-pipelines.yml file this pipeline is defined in order to figure out how it should get triggered.

Kind regards,

Hi @Theodora Boudale, It was a custom pipeline and I was able to trigger the same after adding the selector in the request body. Thanks for the support. 

"target": {
"ref_type": "branch",
"type": "pipeline_ref_target",
"ref_name": "master",
"selector": {
"type": "custom",
"pattern": "Name"

Thanks and Regards,
