Hello, I’m trying to trigger a parameterized Freestyle project build from slack via a Slash Command. The Slash Command is /paramtest and configured as a POST with the URL: [https://JENKINS\_USER:API\_TOKEN@myjenkinsurl.com/job/ParamTest/buildWithParameters?token=TOKEN\_FROM\_JENKINS\_BUILD\_TRIGGER](https://JENKINS_USER:API_TOKEN@myjenkinsurl.com/job/ParamTest/buildWithParameters?token=TOKEN_FROM_JENKINS_BUILD_TRIGGER) The Freestyle project is set up as a Parameterized build with a string parameter called ActiveProject. In slack I can successfully trigger the build with: /paramtest ActiveProject=test param2\_for\_fun The build runs, but I can’t figure out how to get to the parameters passed in. I found some info on the web that there would be a %text% environment variable with this, or that the ActiveProject variable would be set to what was specified in the URL, but it is always the default. I just can’t figure out how to get access to those parameters, and I can’t find any other info online or in the documentation. Any info is very much appreciated. Thanks! ## Jenkins setup: Jenkins: 2.401.3 OS: Windows 10 - 10.0 Java: 11.0.15 - Microsoft (OpenJDK 64-Bit Server VM) ant:497.v94e7d9fffa\_b\_9 antisamy-markup-formatter:162.v0e6ec0fcfcf6 apache-httpcomponents-client-4-api:4.5.14-150.v7a\_b\_9d17134a\_5 bootstrap5-api:5.3.0-1 bouncycastle-api:2.29 branch-api:2.1122.v09cb\_8ea\_8a\_724 build-timeout:1.31 build-timestamp:1.0.3 build-token-root:151.va\_e52fe3215fc caffeine-api:3.1.6-115.vb\_8b\_b\_328e59d8 checks-api:2.0.0 cloudbees-folder:6.815.v0dd5a\_cb\_40e0e command-launcher:106.vb\_a\_b\_8f751309c commons-lang3-api:3.13.0-62.v7d18e55f51e2 commons-text-api:1.10.0-68.v0d0b\_c439292b\_ credentials:1271.v54b\_1c2c6388a\_ credentials-binding:631.v861c06d062b\_4 dark-theme:336.v02165cd8c2ee data-tables-api:1.13.5-1 display-url-api:2.3.8 dotnet-sdk:1.4.0 durable-task:513.vc48a\_a\_075a\_d93 echarts-api:5.4.0-5 email-ext:2.100 envinject:2.908.v66a\_774b\_31d93 envinject-api:1.199.v3ce31253ed13 external-monitor-job:207.v98a\_a\_37a\_85525 file-operations:131.v32b\_e7824fe95 font-awesome-api:6.4.0-2 git:5.2.0 git-client:4.4.0 git-server:99.va\_0826a\_b\_cdfa\_d github:1.37.2 github-api:1.314-431.v78d72a\_3fe4c3 github-branch-source:1732.v3f1889a\_c475b\_ gradle:2.8.2 instance-identity:173.va\_37c494ec4e5 ionicons-api:56.v1b\_1c8c49374e jackson2-api:2.15.2-350.v0c2f3f8fc595 jakarta-activation-api:2.0.1-3 jakarta-mail-api:2.0.1-3 javax-activation-api:1.2.0-6 javax-mail-api:1.6.2-9 jaxb:2.3.8-1 jdk-tool:73.vddf737284550 jjwt-api:0.11.5-77.v646c772fddb\_0 jnr-posix-api:3.1.17-1 jquery3-api:3.7.0-1 jsch:0.2.8-65.v052c39de79b\_2 junit:1217.v4297208a\_a\_b\_ce ldap:682.v7b\_544c9d1512 lockable-resources:1185.v0c528656ce04 mailer:463.vedf8358e006b\_ mapdb-api:1.0.9-28.vf251ce40855d matrix-auth:3.1.10 matrix-project:802.v8013b\_40c7edc mina-sshd-api-common:2.10.0-69.v28e3e36d18eb\_ mina-sshd-api-core:2.10.0-69.v28e3e36d18eb\_ okhttp-api:4.11.0-157.v6852a\_a\_fa\_ec11 pam-auth:1.10 pipeline-build-step:505.v5f0844d8d126 pipeline-github-lib:42.v0739460cda\_c4 pipeline-graph-analysis:202.va\_d268e64deb\_3 pipeline-groovy-lib:671.v07c339c842e8 pipeline-input-step:477.v339683a\_8d55e pipeline-milestone-step:111.v449306f708b\_7 pipeline-model-api:2.2144.v077a\_d1928a\_40 pipeline-model-definition:2.2144.v077a\_d1928a\_40 pipeline-model-extensions:2.2144.v077a\_d1928a\_40 pipeline-rest-api:2.33 pipeline-stage-step:305.ve96d0205c1c6 pipeline-stage-tags-metadata:2.2144.v077a\_d1928a\_40 pipeline-stage-view:2.33 plain-credentials:143.v1b\_df8b\_d3b\_e48 plugin-util-api:3.3.0 postbuildscript:3.2.0-460.va\_fda\_0fa\_26720 powershell:2.0 preSCMbuildstep:71.v1f2990a\_37e27 publish-over:0.22 publish-over-dropbox:1.3.2 publish-over-ftp:1.17 resource-disposer:0.23 scm-api:676.v886669a\_199a\_a\_ script-security:1264.vecf66020eb\_7d slack:664.vc9a\_90f8b\_c24a\_ snakeyaml-api:1.33-95.va\_b\_a\_e3e47b\_fa\_4 ssh-credentials:308.ve4497b\_ccd8f4 ssh-slaves:2.916.vd17b\_43357ce4 sshd:3.312.v1c601b\_c83b\_0e structs:324.va\_f5d6774f3a\_d subversion:2.17.2 text-file-operations:1.3.2 theme-manager:193.vcef22f6c5f2b\_ thinBackup:1.18 timestamper:1.26 token-macro:359.vb\_cde11682e0c trilead-api:2.84.v72119de229b\_7 unity3d-plugin:1.3 variant:59.vf075fe829ccb workflow-aggregator:596.v8c21c963d92d workflow-api:1251.vd4889a\_b\_0a\_065 workflow-basic-steps:1042.ve7b\_140c4a\_e0c workflow-cps:3731.ve4b\_5b\_857b\_a\_d3 workflow-durable-task-step:1278.v94b\_dc2b\_50c6f workflow-job:1316.vd2290d3341a\_f workflow-multibranch:756.v891d88f2cd46 workflow-scm-step:415.v434365564324 workflow-step-api:639.v6eca\_cd8c04a\_a\_ workflow-support:848.v5a\_383b\_d14921 ws-cleanup:0.45 ---

If no one has thoughts on this direct case, a more general question: I’m wondering how much anyone uses triggering with Slash Commands at all - either for a Freestyle project or Pipeline? Is there perhaps an alternative to triggering parameterized builds from Slack? I thought this would be a common use case, but perhaps not? Thanks!
