What does 'the connector bridges the low-code platform and the ERP' mean?
Connectors are the integration building blocks of low-code platforms. An SAP connector handles SAP authentication, BAPI calls, and response parsing — the maker just sees 'Get Purchase Orders' as an action, not the underlying complexity.
2 / 20
What is a 'premium connector' and what does it require?
Low-code platforms distinguish between standard (included in base license) and premium connectors (requiring additional licensing). This licensing model reflects the commercial agreements between the platform vendor and the connected service provider.
3 / 20
What is a 'custom connector that wraps the REST API'?
Custom connectors bridge the gap between low-code and systems that don't have pre-built connectors. A developer defines the connector (endpoint URLs, authentication, actions, schema) using an OpenAPI spec or the platform's connector wizard, then publishes it for makers to use.
4 / 20
What does 'the connector handles authentication automatically' mean?
Connector authentication is configured once (OAuth connection, API key, service account) and then stored securely by the platform. Flows using the connector automatically use the stored credentials, preventing makers from embedding credentials directly in flows.
5 / 20
What is 'data transformation that maps between schemas' in a low-code integration?
Enterprise systems rarely share the same data formats. A low-code integration between an ERP and CRM requires transforming field names, data types, and structure. Platforms provide expression languages (Power Fx, Jinja) and transformation actions to define these mappings without custom code.

Sarah from the Sales team sent a Slack message to the integration team: 'The new lead data isn't showing up in our CRM after it's synced via the low-code platform. Any ideas?' What's the most likely root cause, given this scenario?
Sarah's message indicates a data synchronization problem. The most probable reason is that the scheduled sync times don't match the CRM's update cycle. A high latency API endpoint or authentication issues are less likely given the specific phrasing of her complaint. Manually triggering a refresh isn't a standard troubleshooting step.

You're reviewing a pull request description for a connector that integrates with a legacy database. The PR includes the following text: 'This connector utilizes a pre-built transformation to map JSON data from the low-code platform into a relational format compatible with the Oracle Database. The transformation handles date formatting and string encoding.' What is the primary benefit of this described approach?
The description highlights 'schema mismatch' as a key benefit. Data transformation is crucial when integrating different data models (JSON vs. relational). While simplification and optimization are potential secondary outcomes of using a pre-built transformation, the core purpose is to manage these differences and ensure correct data interpretation.

During a standup meeting, Mark (the Lead Developer) asks: 'Has anyone investigated the performance of the connector integrating with our new marketing automation platform? We're seeing increased latency during lead capture.' What metric should be prioritized to diagnose this issue *first*?
Latency issues in integrations are often related to data volume. While concurrent requests and server CPU can contribute, the immediate cause is likely due to the size of the JSON payloads being transmitted between systems – large payloads inherently take longer to transfer. Analyzing the webhook response time offers a focused starting point.
9 / 20
You're designing a connector that pulls data from a SaaS application via its REST API. The API requires OAuth 2.0 authentication. What does 'the connector handles authentication automatically' mean in this context?
'Automatic authentication' refers to utilizing OAuth 2.0's token exchange process. This eliminates the need for developers to manage sensitive credentials directly within the connector code – a common source of security vulnerabilities. The low-code platform handles the complex token flow, reducing operational overhead.

David, a junior developer, is struggling to understand a message in a code review comment: 'This transformation needs to handle null values gracefully – ensure it doesn't throw an exception when encountering missing data.' What does this primarily indicate about the connector's design?
'Handling null values gracefully' is critical for robust integration design. Simply ignoring nulls can lead to unexpected results and errors. The correct approach involves substituting default values or implementing specific logic based on the application's needs – preventing exceptions and ensuring data consistency.
