New Webhook Endpoint
Issues a key id and a signing secret for one partner. The secret is shown once on this screen and cannot be retrieved afterwards, so have somewhere to put it before you press create.
Credential
Who this key belongs to. It appears on the health strip and in the delivery log.
Names the source system and prefixes the key id. Leave it as ammp unless a second source is being added.
Comma separated addresses or CIDR ranges, for example 5.6.7.0/24. Optional, and defence in depth only: a source address is not an authentication mechanism, so this narrows who can try, never who is believed.
Requests per minute before we answer 429. Sized to stop a sender stuck in a retry loop, not to throttle normal traffic.
