Data Action - Invalid Parameter Values (400

NICE CXone API & Integrations
1

The data action is failing with "invalid parameter values" (400) consistently. It’s returning that error during the POST to /api/v2/integrations/actions/{actionId}/execute. The module accepts a map of string-to-string parameters, passes them to the action, yet the API rejects it. Why is it failing parameter validation? It’s likely the action definition itself is the problem - it’s expecting a different structure or encoding.

For what it’s worth, the action is defined as accepting a JSON payload, and the Terraform module is correctly formatting the parameters as a JSON string. The issue isn’t the Terraform serialization. It’s the Data Action itself.

resource "genesys_cloud_data_action_execution" "example" {
 action_id = "a1b2c3d4-e5f6-7890-1234-567890abcdef"
 parameters = jsonencode({
 "param1" = "value1"
 "param2" = "value2"
 })
}

Here’s what’s been tried:

  • Verified the action ID is correct (200).
  • Confirmed the parameter names match the action definition (404).
  • Tested the API directly with Postman - same error (400).
  • Checked the Data Action configuration in Genesys Cloud - no obvious errors.
  • Module version 1.2.3, Terraform Cloud run agent v13.
