Has anyone figured out why the ServiceNow REST API is returning a 400 error when called from a Genesys Cloud Data Action? The integration works for standard cases, but complex payloads with nested objects fail validation. The endpoint is configured correctly, and the payload structure matches the ServiceNow schema. Error logs indicate a parsing issue on the ServiceNow side, but the JSON appears valid. Need to debug the payload transformation in Genesys Cloud.
{
“payload”: {
“record”: {
“field”: “{{value}}”
}
}
}
Ah, this is a known issue... ServiceNow often rejects flat JSON structures when expecting nested records. Unlike Zendesk's flexible ticket updates, Genes Cloud Data Actions require precise schema mapping. Try wrapping the payload in a `record` object as shown above. This usually resolves the 400 error.
You should probably look at at the payload serialization in your JMeter thread group. Ensure the nested objects are flattened correctly before hitting the endpoint. The 400 error often stems from schema mismatches rather than authentication issues. Digital channel metadata requires a flat structure, not nested arrays. Verify no null values exist for required fields.
