What’s the cleanest way to trigger an outbound call for an agent through the POST /api/v2/conversations/calls endpoint without hitting auth walls? We’ve got a Rust service sitting in Sao Paulo that listens to WebSocket notification streams. When a specific event hits, the Tokio task spins up and tries to place the call. The token refresh logic works fine. We’ve already validated the bearer token against the auth endpoint. The real issue crops up when the HTTP client fires the POST request.
let payload = serde_json::json!({
"from": { "id": agent_id, "name": "System Bot" },
"to": [{ "phoneNumber": "+5511999999999" }],
"wrapUpCode": "completed"
});
let res = client.post("https://api.mypurecloud.com/api/v2/conversations/calls")
.bearer_token(&token)
.json(&payload)
.send()
.await?;
The server keeps throwing a 400 Bad Request. The response body just says invalid_request. I’ve checked the docs and the to array format looks right. Maybe the from.id needs to be a routing queue instead of a direct user ID? Or is there a specific capability flag missing on the OAuth client? We’re running the default Genesys Cloud OAuth scope set. The WebSocket stream confirms the agent is actually logged in and available. Latency from Brazil to the US east coast endpoints sits around 120ms, so timing isn’t the culprit here.
Tried swapping the JSON structure to match the exact example in the developer portal. Still getting the same 400. The headers include Content-Type: application/json and the authorization scope covers conversation:write. Not sure if the API expects a different payload shape for programmatic call creation versus the standard web client. Any chance the from object requires a routingQueue field instead. Just staring at the 400 response for the third time today.
