We are attempting to standardize the visual appearance of our Web Messaging channels across multiple tenant deployments using the CX as Code Terraform provider. The requirement is to dynamically set the launcher button color and position based on the specific deployment context, rather than hardcoding values in the Genesys Cloud UI.
I am using the genesyscloud_webmessaging_deployment resource. According to the documentation, the custom_css attribute should allow us to override the default styles. I have constructed a CSS block targeting the .launcher-button class to change the background color to our brand hex code and adjusted the bottom property to move the launcher higher up the screen.
The plan applies successfully without errors. However, when I inspect the deployed widget in the browser, the styles do not take effect. The default blue button remains in the bottom-right corner. I have verified the CSS syntax in the Terraform file is valid. I also tried using the custom_js attribute to inject a script that modifies the DOM directly, but that approach resulted in a CSP violation error in the console.
Here is the relevant snippet from our Terraform configuration:
resource "genesyscloud_webmessaging_deployment" "branding_test" {
name = "Branding Test Deployment"
description = "Testing custom CSS injection"
custom_css = <<-EOT
.launcher-button {
background-color: #003366 !important;
bottom: 100px !important;
right: 20px !important;
}
EOT
}
Environment details:
- Terraform Provider: 1.15.2
- Genesys Cloud Region: eu-west-1
- Browser: Chrome 120
- Deployment Status: Active
Has anyone successfully overridden the launcher styles via Terraform? Are there specific class names or selectors that are whitelisted for the custom_css attribute?
I ran into this exact headache last quarter. The genesyscloud_webmessaging_deployment resource is finicky with multiline strings in Terraform. If you paste a standard CSS block, the provider often strips newlines or escapes characters incorrectly, resulting in an empty or malformed CSS field in the Genesys API.
Try wrapping your CSS in a heredoc block (<<-EOF) to preserve formatting, and make sure you’re targeting the correct selector. The launcher button class changes depending on the SDK version, but .launcher-button is the standard hook.
resource "genesyscloud_webmessaging_deployment" "my_deployment" {
name = "Standardized Launcher"
description = "Terraform managed deployment"
# Use heredoc to prevent newline stripping
custom_css = <<-EOF
.launcher-button {
background-color: #FF5733 !important;
border-radius: 50% !important;
}
.launcher-button:hover {
background-color: #C70039 !important;
}
EOF
# Ensure other required fields are present
enabled = true
}
Also, double-check that you aren’t overriding this with inline styles in the SDK configuration object. Inline styles always beat injected CSS, so if your JS config sets launcherColor: '#000000', your Terraform effort will be invisible. You might need to remove that property from the SDK init to let the CSS take over.
Thanks for the tip on the heredoc. That actually fixed the parsing issue on my end. The provider was definitely stripping the newlines and breaking the CSS structure. I switched to <<-EOF and the Terraform plan now shows the full CSS block correctly without any escaping errors. It’s a bit annoying that the provider is so strict about formatting, but it works now.
I did notice one thing though. The selector you mentioned works for the button, but it doesn’t affect the chat window background. I had to add .gcw-widget-container { background-color: #f0f0f0; } to the block to get the full look. Here is the final working config for anyone else hitting this:
resource "genesyscloud_webmessaging_deployment" "main" {
name = "Prod Launcher"
custom_css = <<-EOF
.gcw-launcher-button { background-color: #0056b3; }
.gcw-widget-container { background-color: #f0f0f0; }
EOF
}
Just wanted to share the complete block since the docs are a bit vague on the specific class names needed for the window styling.
