# Developer Extensibility

16 filters and 6 action hooks let you customize every aspect of dispatch, payload, headers, and retry behavior.

The plugin's internal dispatch pipeline is fully extensible via WordPress filters and actions. Customize dispatch conditions, payload shape, request headers, URL rewriting, HTTP timeouts and arguments, retry count and delay, queue batch size, trigger discovery, and webhook data serialization.

## Filters

`fswa_should_dispatch`, `fswa_payload`, `fswa_webhook_payload`, `fswa_webhook_url`, `fswa_headers`, `fswa_http_args`, `fswa_http_timeout`, `fswa_http_connect_timeout`, `fswa_max_attempts`, `fswa_backoff_delay`, `fswa_queue_batch_size`, `fswa_require_https`, `fswa_capture_payload`, `fswa_normalize_object`, `fswa_available_triggers`, `fswa_webhook_data`.

## Actions

`fswa_success`, `fswa_error`, `fswa_skipped`, `fswa_webhook_response`, `fswa_glue_post_dispatch`, `fswa_webhook_saved`.
