APIСправочникWebhook events
message.updated
A message changed in a way you can see: its delivery status (delivered, read, failed and
its error_code), its text, or it was deleted.
Header Parameters
X-Lalexi-Event*string
The event name, the same as event in the body.
X-Lalexi-Delivery*string
The delivery's id, the same as id in the body. It stays the same across retries — deduplicate on it.
Format
uuidX-Lalexi-Timestamp*string
When this attempt was signed, in Unix seconds. Part of the signed string.
X-Lalexi-Signature*string
sha256= followed by the hex HMAC-SHA256 of {X-Lalexi-Timestamp}.{raw body}, keyed with
the endpoint's whole secret (whsec_…). Compute it over the raw bytes you received — not over
re-serialised JSON — and compare in constant time.
