[WPGraphQL Headless Webhooks] Beta Release

[josephfusco]

User Story

As a Headless Developer, I want to trigger a build whenever content or configuration changes, so that my static site updates.

As a Headless Developer using WPGraphQL Smart Cache, I want to leverage smart cache for on-demand invalidation.

Acceptance Criteria

• Only administrator user role can access webhook plugin settings (manage_options)
• Post body includes wpgraphql-smart-cache keys
• Post body includes URI for invalidation if keys are not being used
• User can select POST or GET
• User can include custom auth headers
• Support multiple events per webhook entry (possibly solved by smart cache)
• User can "pause" a webhook

Technical Notes

1. When pausing a webhook, consider utilizing WordPress' "trash" post status, and unpausing publishes.

Future Ideas

1. Batch processing webhooks (e.g. multiple authors hitting save within 2 mins)
2. Ability to custom order webhooks to handle platform edge cases
