Try this query from our postman collectionfetchIssuesbyPipeline. This query will allow you to retrieve the issues from a single given pipeline, we currently don’t support retrieving issues from multiple pipelines within a single request due to the potential size of the query. Here is the code for the query:
query ($pipelineId: ID!, $filters: IssueSearchFiltersInput!) {
searchIssuesByPipeline(pipelineId: $pipelineId, filters: $filters) {
nodes {
id
title
}
}
}
