Create Supabase Sync

Create a Supabase Storage Sync for a collection and start the initial backfill. Returns the sync; indexing runs asynchronously.

post/v2/collections/{collection_name}/sync/supabase

Path parameters

collection_namestring required

Destination collection.

Headers

authorizationstring nullable

Bearer {api_key}. Your Captain API key.

Request body

bucketstring required

Supabase Storage bucket to keep in sync with the collection.

prefixstring

Key prefix to scope the sync. Empty syncs the whole bucket.

endpoint_urlstring required

Supabase S3 endpoint, e.g. https://PROJECT_REF.storage.supabase.co/storage/v1/s3

regionstring

Region for the S3 protocol.

access_key_idstring required

Supabase S3 access key ID.

secret_access_keystring required

Supabase S3 secret access key. Stored securely, never returned.

processing_type'advanced' | 'basic' required

Parsing tier.

include_patternsstring[]

Glob patterns; only matching keys are synced.

exclude_patternsstring[]

Glob patterns; matching keys are excluded.

deletion_policy'mirror' | 'archive' | 'ignore'

How to propagate objects removed from the source: mirror removes them from the collection so they no longer appear in search; archive keeps the document's content but marks it archived, excluded from search by default and surfaced with include_archived: true; ignore leaves the indexed copy in place.

custom_metadataobject

Static metadata applied to every synced document.

sync_interval_minutesinteger nullable

Scheduled reconcile cadence (minimum 5; null = manual).
