Building on Oyapost
Webhooks
Oyapost can POST to your URL when a post is published, so you do not have to poll.
Set it up
Open Settings, then Webhook. Enter an HTTPS URL and save. Oyapost shows a secret you can use to check that the request came from your account. Localhost URLs are allowed for testing.
The request
A published post sends event post.published. The header X-Oyapost-Event carries the same name, and X-Oyapost-Signature is the body signed with your secret. The JSON body includes post_id, platform, integration_id, link, caption, and published_at.
