Question 1

What is an API endpoint?

Answer 1

The URL where you send API requests. It’s specific to the AWS service and Region. Format: servicename.region.amazonaws.com (Example: connect.us-east-1.amazonaws.com)

Question 2

What is AWS Signature Version 4 (SigV4)?

Answer 2

The authentication method required for Amazon Connect APIs. It uses IAM credentials to cryptographically sign API requests to prove identity.

Question 3

What are the 4 required parameters for Amazon Connect API authentication?

Answer 3

Access Key ID | Secret Access Key | AWS Region (e.g. us-east-1) | Service Name (e.g. connect or profile)

Question 4

What is an Access Key ID?

Answer 4

Part 1 of IAM user credentials. Format: AKIAIOSFODNN7EXAMPLE. Used with secret access key to authenticate API requests.

Question 5

What is a Secret Access Key?

Answer 5

Part 2 of IAM user credentials. Format: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY. Must be kept secure and used with access key ID.

Question 6

What is a Session Token in API authentication?

Answer 6

Temporary credential used when assuming an IAM role. Provides same permissions as long-term credentials but expires after a set time.

Question 7

What is a Postman Collection?

Answer 7

A container that organizes related API requests and shares configuration (like authentication) across all requests within it.

Question 8

What are the 3 components of an Amazon Connect API URI?

Answer 8

Resource type (/users /queues /contacts) | Instance ID | Resource ID (for specific resource operations)

Question 9

What does the PUT HTTP method do?

Answer 9

Creates a new resource OR updates an existing resource. Always requires a request body with complete resource data.

Question 10

What does the DELETE HTTP method do?

Answer 10

Removes/deletes a resource. Only requires the URI - no request body needed.

Question 11

What does the GET HTTP method do?

Answer 11

Retrieves information about a resource. Returns data about the specified resource without modifying it.

Question 12

What does the POST HTTP method do?

Answer 12

Creates a new resource or submits data for processing. Requires a request body with the data being sent.

Question 13

What does a 200 HTTP status code mean?

Answer 13

Success - the request was completed successfully. Resource was created | updated | retrieved | or deleted as requested.

Question 14

What is a Request Body (or Request Model)?

Answer 14

JSON data sent with PUT or POST requests that contains the information needed to create or update a resource.

Question 15

What is a Response Body (or Response Model)?

Answer 15

JSON data returned by the API after processing a request. Contains result data like created resource IDs or error messages.

Question 16

What is the AWS SDK?

Answer 16

Software Development Kit - libraries (boto3 for Python | aws-sdk for Node.js) that simplify making authenticated API calls to AWS services.

Question 17

Step 1: Setting up Postman - What do you create first?

Answer 17

Create a new Collection to organize your Amazon Connect API requests.

Question 18

Step 2: Setting up Postman - Where do you configure authentication?

Answer 18

Configure authentication at the Collection level so all requests in that collection inherit the auth settings.

Question 19

Step 3: Setting up Postman - What auth type do you select?

Answer 19

Select AWS Signature as the authorization type for Amazon Connect APIs.

Question 20

Step 4: Setting up Postman - What 4 values do you enter for auth?

Answer 20

Access Key ID | Secret Access Key | AWS Region | Service Name (connect)

Question 21

Step 5: Setting up Postman - How do you build the request URL?

Answer 21

Combine endpoint (connect.region.amazonaws.com) + path (/users/instance-id or /queues/instance-id/queue-id)

Question 22

Step 6: Setting up Postman - What do you select for the HTTP method?

Answer 22

Choose the method based on operation: GET (retrieve) | PUT (create/update) | POST (create/submit) | DELETE (remove)

Question 23

Step 7: Setting up Postman - When do you need a request body?

Answer 23

PUT and POST methods require a request body. GET and DELETE do not.

Question 24

Step 8: Setting up Postman - What do you check after sending a request?

Answer 24

Check the status code (200 = success) and examine the response body for returned data or error messages.

Question 25

What are the 3 testing scenarios you should verify in Postman?

Answer 25

Successful creation (PUT with body expect 200) | Successful retrieval (GET expect 200 + data) | Successful deletion (DELETE expect 200)

Question 26

After Postman testing succeeds what is the automation approach?

Answer 26

Write Lambda function code using AWS SDK (boto3/aws-sdk) that makes the same API calls Postman successfully made.

Question 27

How does Lambda authenticate to Amazon Connect APIs?

Answer 27

Lambda uses IAM role permissions. If the Lambda execution role has Connect permissions then boto3/aws-sdk handles authentication automatically.

Question 28

What is the Lambda automation flow for API integration?

Answer 28

Lambda triggered by event | Lambda receives input data | Lambda uses SDK to call Connect API | API processes and responds | Lambda returns result

Question 29

Why test in Postman before writing Lambda code?

Answer 29

Validates endpoint URLs are correct | authentication works | request body format is proper | expected responses are understood. Reduces debugging in code.

Question 30

What IAM permissions does the API user need?

Answer 30

The IAM user (for Postman) or IAM role (for Lambda) must have permissions for the specific Amazon Connect operations being performed (e.g. CreateUser DeleteUser).
