GitLab integration in Katalon True Platform API triggering

Last updated: April 2026

This document explains how to integrate GitLab in Katalon True Platform, to trigger API calls.

Scenario

This integration focuses on using the GitLab CI/CD pipeline to make an API call that triggers a pre-scheduled test execution that is defined and managed within Katalon True Platform.

Purpose and strategic value

The primary purpose is to be able to trigger scheduled executions in Katalon True Platform from the GitLab pipeline. This approach allows the GitLab CI process to initiate complex testing workflows that are centrally configured in Katalon True Platform, enabling orchestrated, immediate execution of predefined test runs.

Key takeaways

The key takeaway is the ability to trigger scheduled executions in Katalon True Platform from the GitLab pipeline using a PUT request to the Katalon True Platform API endpoint.

Best practice steps

Obtain scheduler and run configuration IDs

• Schedule the test run in Katalon True Platform (e.g., named GitLab_Pipeline_TestOps).

• Extract the values for schedulerId and scheduleId from the response payload of the scheduled execution.

Configure GitLab CI/CD variables

• Add all necessary API parameters (like KATALON_API_HOST, KATALON_API_TOKEN, KATALON_SCHEDULER_ID, etc.) as masked variables in the GitLab project settings.

Compose the .gitlab-ci.yml file

• Define a stage (e.g., execute_tests) and a corresponding job (e.g., trigger_katalon_execution).

• Use the Katalon Docker image (or another image capable of running curl).

stages:
 - execute_tests
trigger_katalon_execution:
 stage: execute_tests
 image: katalonstudio/katalon:latest
 variables:
   API_ENDPOINT: "https://$KATALON_API_HOST/v2/schedules/test-runs"
   JSON_DATA_BODY: >
     {
     	"startTime":"2025-10-15T06:31:00.581+00:00",
       "schedulerId": $KATALON_SCHEDULER_ID,
       "runConfigurationId": $KATALON_RUN_CONFIG_ID,
       "action": "INSTANCE_RUN"
     }
 script:
   - apt-get update -qq
   - apt-get install -y curl
   - echo "Executing Katalon API call to trigger schedule $KATALON_SCHEDULER_ID"
   - |
     curl -X PUT \
       "$API_ENDPOINT" \
       -H "Authorization: Bearer $KATALON_API_TOKEN" \
       -H "x-organization-id: $KATALON_ORG_ID" \
       -H "x-project-id: $KATALON_PROJECT_ID" \
       -H "Content-Type: application/json" \
       --data-raw "$JSON_DATA_BODY"
 rules:
   - if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH

Define YAML variables and JSON payload

• Set the full API endpoint URL within the YAML, using the host variable: API_ENDPOINT: "https://$KATALON_API_HOST/v2/schedules/test-runs".

• Define the JSON_DATA_BODY using multi-line syntax (>). The payload must include:

  • "startTime" (Note: Even if startTime is set in the future, the API call will trigger the tests immediately).

• "schedulerId": $KATALON_SCHEDULER_ID

• "runConfigurationId": $KATALON_RUN_CONFIG_ID

• "action": "INSTANCE_RUN"

Execute the API call using cUrl

• The script must first ensure curl is installed: apt-get update -qq and apt-get install -y curl.

• Execute the API call using the curl -X PUT command:

  • The command targets the $API_ENDPOINT.

  • It must pass the required authentication and identification headers: Authorization: Bearer $KATALON_API_TOKEN, x-organization-id: $KATALON_ORG_ID, and x-project-id: $KATALON_PROJECT_ID.

  • It must include the JSON payload using --data-raw "$JSON_DATA_BODY".

$KATALON_API_TOKEN

Note: Make sure to check and update the token value to ensure it is valid.

$KATALON_ORG_ID = <<the value of x-organization-id>>

$KATALON_PROJECT_ID = <<the value of x-project-id>>

Verify execution

• After the GitLab job runs successfully (under Build ▶️ Jobs), verify that a new test execution starts immediately in Katalon True Platform under the Executions tab.

Results

Conclusion

Integrating GitLab with Katalon True Platform via the API allows GitLab to serve as a centralized trigger for pre-configured test schedules in Katalon True Platform. This separation of duties ensures that test environment configuration and execution management remain centralized within Katalon True Platform while execution initiation is seamlessly integrated into the automated CI/CD flow. Using the Katalon True Platform API essentially turns the GitLab pipeline into a sophisticated remote control for automated testing.
