Path Parameters

collectionId · string · required

This is the identifier for the collection related to the request. Every project has default collections: default-solana and default-polygon.

The create-collection API will result in collections with UUID formatted collectionId. Example: 9c82ef99-617f-497d-9abb-fd355291681b

The create-collection-idempotent API allows you to specify an arbitrary identifier during the initial request. Example: your-custom-identifier
