I have opened the Push Notification and the Broadcast Capability at developer Capabilities, but when I call the api https://api-manage-broadcast.sandbox.push.apple.com:2195/1/apps/already change to my Identifiers/channels, I always got the "TopicMismatch".
Did I set something wrong somewhere?
Is "already" your Bundle ID?
Can you share the complete HTTP/2 request (headers and payload) and the full response from APNs please.
If that is not appropriate, then we need at least: apns-request-id, apns-channel-id, and the exact time (with Time Zone) you sent the request that failed.
apns-request-id: 6330D701-4C13-A262-00E6-9D9F2CF0E0E5
exact time: 2024-11-26 18:27:04 GMT+8,
the timestamp -> 1732616824
I'm not sure if this already counts as successfully binding the bundle ID for broadcast push notifications. For my JWT Bearer, I used the PRIVATE KEY from the .p8 certificate.
We finally found that creating a new identifier and a new p8 file can call this API normally. If the broadcast function is directly enabled in the old project, the request API form channel management cannot be performed.
