Understanding API Connector Authentication

When setting up an API connector, which authentication method requires you to provide a token that is sent with each request to verify your identity?

A Basic Authentication using username and password

B API Key Authentication using a token in the header

C OAuth 2.0 Authorization Code flow

D No authentication required

💡 Hint

Think about a method where a secret token is included in every request header.

API Key Authentication involves sending a token with each request, usually in the header, to identify and authorize the client.

Setting the API Endpoint URL

You want to connect to a weather service API to get current weather data. Which part of the API connector setup is crucial to specify the exact data you want?

A The API endpoint URL including the path and query parameters

B The API provider's company name

C The API documentation link

D The API response format (JSON or XML)

💡 Hint

Consider where you tell the connector what specific data to fetch.

The API endpoint URL defines the exact resource and parameters to request from the API server.

Troubleshooting API Connector Errors

You set up an API connector but receive a 401 Unauthorized error when testing. Which is the most likely cause?

A The API endpoint URL is misspelled

B The response format is set to XML instead of JSON

C The API server is down

D Incorrect or missing authentication credentials

💡 Hint

401 errors usually relate to permission or identity issues.

A 401 Unauthorized error means the server did not accept the credentials provided, often due to wrong or missing authentication details.

Choosing Between GET and POST Methods

When configuring an API connector, which HTTP method should you use if you want to send data to the server to create a new record?

A POST, because it sends data to the server to create or update resources

B GET, because it retrieves data without changing the server

C DELETE, because it removes data from the server

D PUT, because it only retrieves data

💡 Hint

Think about which method sends data to the server to add something new.

POST requests are used to send data to the server to create or update resources, unlike GET which only retrieves data.

Handling API Rate Limits in Connector Setup

Your API connector setup must handle a limit of 100 requests per minute. Which approach best prevents exceeding this limit?

A Send all requests as fast as possible and retry failed ones later

B Ignore the limit because the API will queue requests automatically

C Add a delay between requests to keep the request rate under the limit

D Use multiple API keys to bypass the limit

💡 Hint

Consider how to control the speed of your requests to avoid errors.

Adding a delay between requests ensures you do not exceed the allowed number of requests per minute, preventing errors or bans.
