# Get pipeline
Use the get ingest pipeline API operation to retrieve all the information about the pipeline.
## Retrieving information about all pipelines
The following example request returns information about all ingest pipelines:
```json
GET _ingest/pipeline/
```
{% include copy-curl.html %}
## Retrieving information about a specific pipeline
The following example request returns information about a specific pipeline, which for this example is `my-pipeline`:
```json
GET _ingest/pipeline/my-pipeline
```
{% include copy-curl.html %}
The response contains the pipeline information:
```json
