Operational alerts people can act on
Every alert carries useful context and a safe link into the right Postly screen. Email approval requests also include short-lived, single-use Approve and Reject links, plus the normal Review in Postly option.
Discord
Rich embeds that keep communities and operating teams informed without exposing sensitive payload data.
Signed HTTPS
HMAC-signed JSON for automation platforms and custom services, with rotation, tests, retries, and delivery history.
Event coverage
From scheduled post to final outcome
Choose only the events each destination needs. Postly preserves operational context while keeping secrets, content, and API keys out of delivery history.
post.publishedCelebrate or continue a workflow after every destination publishes.
post.partially_publishedRoute a mixed result to the right operator before a campaign stalls.
post.failedEscalate failed posts immediately with a direct path back to Postly.
post.approval_requestedBring reviewers into the approval flow without relying on inbox refreshes.
post.approved / post.rejectedKeep campaign systems and collaborators aligned with each decision.
connection.expiring / connection.expiredReconnect social accounts before scheduled publishing is interrupted.
