Blueprint Custom Data Connectors YAML Builder Enhancements
We continue to ship new ways to simplify custom data connections creation with the Data Connector Agent and Blueprint. This month we added two great enhancements within the Blueprint YAML Builder:
Two-way synchronization: Edits made directly in the blueprint YAML Builder, instantly reflect in the UI components. This ensures seamless consistency between the visual editor and the YAML editor.
New templates: Added three pre-configured templates to accelerate initial setup and configuration. The templates helps building Blueprint YAML files for connections that require:
OAuth2 with pagination: For APIs with OAuth2 Client Credentials and offset-based pagination.
Cursor pagination: For API using a next_page_token for pagination
External variable loop: For connectors that need to loop through external variables fetched from a source river using {ext.variable_name} syntax.
