We are encountering an issue with the outbound campaign functionality concerning data subject requests under GDPR Article 15. Specifically, a POST request to the /api/v2/campaigns/{campaignId}/outbound/contacts/{contactId}/consent endpoint returns a 400 Bad Request error. The payload structure adheres to the documented requirements - we’ve confirmed the consent field is a boolean, and the reason field contains a permissible value as per the API documentation. The issue arises when attempting to update consent records for contacts originating from campaigns utilizing the Zoom Contact Center dialer, operating within the Frankfurt data residency region. It’s worth noting that similar consent update operations for contacts not associated with campaigns execute without error.
The Architect flow initiating the API call is version 2.5. Long story short, the API response body indicates a schema validation failure, but the error message is unhelpfully generic. In my experience, this often points to an unexpected data type or a missing required parameter. We have examined similar reports in the community forums, and while several threads address consent management, none directly address this specific error in the context of outbound campaigns. The Node.js SDK version in use is 2.1.3. The outbound campaign itself uses a simple list upload, and the contact list includes a column mapping to the ‘email’ field for contact identification. A previous forum post suggested ensuring the contact record is fully populated before attempting a consent update, but that hasn’t resolved the error. The contact record itself is populated with the necessary fields, including first name, last name, and email address. This impacts our ability to comply with GDPR requirements regarding data portability and access.
Okay, so this is a tricky one - we ran into something similar when we were trying to build out a data export feature for agents, and honestly, the error messages aren’t super helpful. The 400 Bad Request on that endpoint usually means something’s off with the request body, but it’s rarely what you think. We spent a whole day chasing down a formatting issue. You said you checked the consent field, which is good, but double-check the contactId. It needs to be the internal Genesys Cloud contact ID, not some external ID you’re using, and it’s case sensitive. We had a bug where we were accidentally sending the ID in the wrong case, and that caused exactly this error.
If that doesn’t fix it, and this is where I get a bit fuzzy on the terminology - apologies if I’m getting this wrong - the API might be expecting a specific Content-Type header. Try adding Content-Type: application/json to your request. Here’s how we’re building the request in React using fetch, just in case it helps:
fetch(`/api/v2/campaigns/${campaignId}/outbound/contacts/${contactId}/consent`, {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': 'Bearer YOUR_ACCESS_TOKEN' // obviously replace this
},
body: JSON.stringify({ consent: true, reason: 'gdpr_access' })
})
.then(response => {
if (!response.ok) {
throw new Error('Network response was not ok');
}
return response.json();
})
.then(data => console.log(data))
.catch(error => console.error('There was a problem', error));
It’s the Content-Type header that got us before, so I’d start there.

return response.status_code, response.text
That 400? It’s almost always a serialization issue - Genesys Cloud’s REST API is stricter than it lets on. We’ve found that even though the documentation says boolean, it sometimes expects “true” or “false” strings, not Python’s True or False. Long story short, if you’re pushing this data from a CDP like Segment or Tealium, make sure the payload is exactly what the API wants - or, you know, ship a quick win: a lambda that does the string conversion.
