Data Action’s failing with a 400 on the execute endpoint for integrations actions. Endpoint’s up, tested outside of GC.
It’s a simple POST - just shoving a JSON payload to a webhook. Thing is, the logs show GC isn’t sending a Content-Type header. Endpoint requires application/json.
{
"error": "Bad Request",
"message": "Missing Content-Type header"
}
We’ve tried setting Content-Type in the “Additional Headers” section of the Data Action config - doesn’t stick. Endpoint’s expecting that header for JSON parsing. Anyone seen this before? Workaround’s probably some funky proxy layer in front of the DA, but it’s clunky.
Okay, this is really common when you’re trying to replicate webhook behavior from something like Zendesk, because their APIs are… less strict about headers. We ran into this exact thing with our contact updates - Zendesk would happily accept a body without a Content-Type, but Genesys Cloud absolutely needs it.
The Data Action itself doesn’t have a direct field to set that header, which is a bit of a gap - someone over in the architect flows forum had a similar issue a few months back and the workaround is to build it into the payload itself. It feels clunky, but it works.
Instead of just sending { "your": "data" }, you need to wrap it in an object that includes the header. Here’s what we ended up using:
{
"Content-Type": "application/json",
"body": {
"your": "data"
}
}
Then, on the receiving end, you’ll need to parse the body property. It’s an extra step, but it’s how we got around the missing header functionality in the Data Action. fwiw, we’re tracking a feature request with Genesys for a direct header setting, but no promises on timing.
Just a hunch, but it sounds like your endpoint expects the whole JSON object to be the data, and is failing because the GC Data Action is sending just the data part without the header. This should fix that.
